MGB - Test Start, Test Drive

Today's post covers the initial tests of all the changes that I did this past year on the little MGB. It's been quite a year. In August of 2016, I picked up a little British car to bust my knuckles on over the winter. I needed a break from the bus, and it looked like it was going to be a cosmetic fixer. As you've read along this past year, you learned as I did that there was much more to it than that. The brakes were squishy on the drive home, so I went to redo them only to lose the master cylinder in the process. I went to replace the brake master cylinder and had that scope explode into redoing the clutch master cylinder as well. We found rust-through in the floor under the nasty carpet. We found the front suspension bushings has been replaced with window insulation... or at least it looked like it. The coolant pump was failing. The fuel tank was leaking. So much to do and fix. Before I turned the key, though, I changed the oil and oil filter.

Hydraulics

We replaced both front disks, pads and hoses. In the rear, we replaced all of the brake parts: shoes, hardware, drums, wheel cylinders and the one hose. We replaced the brake master cylinder and polished the vacuum assist. Last, we replaced the fluid from end-to-end (kinda obvious with everything else getting redone). On the clutch, we replaced the master cylinder. Between the two master cylinders, we tore down, cleaned and painted the pedal box and pedals. The pedals got new rubber pads as well. Detailed postings 1, 2 and 3.

Body

We ripped out the passenger and driver floors. The rails were repaired, flattened and ground to bare metal. We measured, drilled and ground-to-metal for plug and seam welding the new floors and then had a party to weld them in. The seams were sealed with black seam-sealer and then we experimented with flex-seal to 100% fill the little gaps. Undercoating was applied. I didn't post on it, but in the rear of the little cabin, a prior owner (PO) had cut a big section out of the wall between the cabin and trunk. I repaired that big hole while leveraging the opening to install 2 6x9" Polk Audio speakers. The trunk lid was removed, cleaned, splits were welded and the underside painted. The trunk floor was cleaned, painted and sound deadener was added. The lid had new hinges installed, and the gap on the driver-side accounted for with washers so the trunk now seals all the way around. Detailed postings 1, 2 and 3.

Fuel

The tank was removed and sent to a radiator shop for cleaning and lining. All new fasteners were used during install, and we replaced the hoses, hose clamps, and float / level-sender. Up front, new hoses were installed and a discovered-to-be-faulty upside-down safety switch was replaced with another filter. I will be restoring a safety switch later. We discovered this system leak during final system testing. Detailed posting here.

Cooling

One of the first things we learned about from British Auto Works was the failing coolant pump. This system was the last to get our attention, though. We pulled the pump and the radiator. The radiator was treated with a vinegar and distilled water solution to de-rust / de-scale as was the heater (though it was done in-place). The coolant overflow bottle was paint-stripped and polished and a new pump installed. All new hoses and mostly-new hose clamps were installed as was the thermostat and thermostat housing. Detailed postings 1 and 2.

Front Beam
Second in scope only to the floor replacement, I spent last winter rebuilding the front suspension and steering. The steering mechanism got a clean-up, new gaiters, oil and new tie-rod ends. The suspension was completely refreshed, including new poly-impregnated rubber bushings all around, lots of paint prep and painting, new lower control arms, new front shocks, new front wheel bearings and upgraded sway-bar bushings. It's practically an entirely new front end. Detailed postings about the steering here and here, the front beam 1, 2, 3 and 4. Let's not forget replacing the engine mounts. That was fun.

Testing

Along the way, everything was tested to some degree. The cooling system doesn't leak at rest. The suspension doesn't make noise no matter who is jumping up and down on the bumpers. We stomped on the floors from above and beneath. The clutch engages when the pedal is depressed... and the engine isn't running. The brakes stop the car from rolling when nudged in the garage. These little tests gave us confidence to keep going, and believe that the system was ready. Eventually, you have to put gas in the tank and turn the key.

The last thing you do before you test is hookup the battery. I verified that the battery still had 12V (I was shocked it didn't need a charge), and then connected the leads. The key had been turned to RUN to unlock the steering, so the fuel pump started up. Fuel fountained under the hood, so we tightened a few things, and ultimately removed a broken flip-over safety switch. Once solved, I hopped into the driver seat, put the car in neutral, pulled the hand brake and turned the key again. Fuel pump started up, so I waited a second. After confirming that the gas-fountain wasn't happening I turned the key to start. The engine fired up almost instantly. I revved the engine a few times, and looked for exhaust color. There really wasn't any exhaust, so early concerns about running rich may not have merit. No black smoke to indicate oil nor sweet white smoke to indicate coolant either.
Test Successful.

A Drive
Running the engine in my garage felt awesome, but to really test many of the systems, we need some straight road, and more gas.. and a seat for a passenger and some seat belts. With the new floor came new embedded nuts for the bolts for the seat. this made the seat install a 10 minute effort even as I helped C on his new ride. Add in the retractable seat belts I bought last fall and I'm ready for a street test. Once the rain stops. Oddly enough, during the overnight after the test start, the battery ran down to nearly 0. I must have left the key in the ACC or RUN position, causing systems to stay active all night. Jeez. Road test has to wait while I charge the battery. While waiting, I noticed the front driver running light wasn't working and fixed it with some DeOxit and some patience. I rooted around and found a couple of bolts which could hold the steering column plastic covers on and put that together. I found myself wiping down seats and fiddling with things waiting for the nice weather to arrive.

Finally, I had an opportunity. We had an unseasonably nice stretch during the week and the weekend following was absolutely stunning: upper 60's and clear skies. So, I moved the herd of cars around the driveway, and pushed the MG out of the garage. With a clear rear-view to match the clear sky, I jumped in, fired it up and backed down the driveway. It's loud, and after a little it's-cold sputtering, it settled down. I was able to move through the gears easily; the clutch responded very well. The brakes still had some spongy in them, but I sped off down the street anyway. I drove maybe a mile around the neighborhood, and then started noticing all of the systems that were not working: everything on the green circuit. I chose not to drive to the gas station and instead drove home.

Upon arrival, I discovered that the thermostat housing was leaking. I torqued it down with a plan to look for a leak there on my next test flight. No gas leaked from any fuel line, the brakes remained consistently spongy so I'll need to do another round of bleeding there. The exhaust is loud everywhere with pop-pop-pop noises on deceleration, telling me there's an exhaust leak. Maybe multiple. Let's not forget the green circuit isn't working. Ultimately, though I declare Test Successful.

It was awesome to get that little car going. The throttle response is great, the steering is tight, the suspension over bumps is mellow. I have a few things still to do before it's really road-ready, but none of it is scary. Except maybe getting a top. That may have to wait until I can pay someone else to do it.

Thanks, as always, for following along.

MGB - Front Suspension Refresh (Part 4)

This post finishes up the front end rebuild I started in Parts 1 (See MGB - Front Suspension Refresh Part 1), 2 (See MGB - Front Suspension Refresh Part 2) and 3 (See MGB - Front Suspension Refresh Part 3). At this point, the front beam is back in the car. The front shocks (and upper control arms) and lower control arms are installed with the spring pans. Today we will get the springs in, the swivels mounted and the front sway bar attached to the lower arms. By the end, the car could go back on the ground. The how-to for the springs I lightly touch on because it is pretty well documented around the internet. Not so much with the sway bar, so that's a little long.

Spring Thing
Back in Part 1, I described the concerns about how the springs were under load when the lower control arm was to be removed and that some level of care was needed to prevent it from launching across the garage. That concern returns as we approach the install. I followed the exact same routine: zip-tie the upper end of the spring to the top of the beam. Getting the zip-ties in the right spot may take a few tries with the jack (during the Jack Be Nimble step), but for now, just get the spring all the way up in the beam pocket and zip tie them so they are mostly in the right spot. Once the springs are suspended from the beam, we move on to the swivels. I did one side at a time, but I don't think there's a compelling reason to other than I confuse easily.

Swivels, bottom mount
The swivels are really nicely balanced lumps of steel, when they are mounted to the suspension. When you are holding them in your hands, or trying to attach them, however, they feel unwieldy. So, to protect yourself from, uh, yourself, put something soft under the end of the beam to catch the swivel when it inevitably topples over. It will topple. Since I had a bunch of things shipped, I took a larger flat box and filled it with the crumpled newspaper and air-filled bags that arrived with the parts. I highly recommend it. The alternative is a damaged swivel. Anyway, take the swivel for the side you're working on (caliper is on the rear), and fit the lower mount into the lower control arm. Thread the bolt from the kit from the front to the rear, minding the order of the washers (nut - washer - rear arm/bushing - swivel - front arm/bushing - washer - bolt head). Once you thread the castle nut on, you may feel driven to crank it on tight. Don't do that yet. Get is on pretty well, though; finger tight.

Jack Be Nimble
With the swivel attached at the bottom, it will want to fall over, especially when you start lifting the lower control arm with your jack. To prevent that, I looped a stretch of bailing wire around the top of the swivel and then around the shock absorber. This loosely held it upright, but didn't restrict movement. Now the fun part begins. Lift the lower control arm under the spring and set the inner edge of the spring inside the spring cup. Now, set your jack as we did in Part 1, on the outer edge of the underside of the spring cup. Slowly start raising the jack. I did it in spurts and then wiggled or rubber-mallet'd the bottom of the spring so it would shift in the spring cup. My thinking was that the cup was rotating 90* so the spring would be under weird tension as is was set into place, putting more pressure on the inner edge than the outer edge of the spring. I don't think it did much other than create more danger of the spring flying out, so consider that optional.

As I got closer to fully-installed, I found that the spring tension was greater than the weight of the car. I mean that the car started lifting off the jackstand before the top of the swivel was within an inch of the holes lining up. If you have a friend, not even a very heavy friend, have him or her sit on the wing over the wheel well. I was flying solo, so I stacked tires on the wing instead. Yes, that actually worked.

Swivels, top mount
As I alluded to in Jack Be Nimble, most of the top mount work is getting the jack positioned right, and raising the swivel while keeping the car solid on the stands. Once the holes in the upper control arm / shock absorber align with the hole in the top of the swivel, it's easy. I found that getting the top of the swivel to sit in the arms wasn't simple though. I needed to loosen the bolts that hold the top arms together a little bit so the swivel top could fit. You may need to do that same, just don't forget to torque them back down when you're firming up all of your fasteners.

Now do that again for the other side. I found that the first one took at least twice as long as the second side. Ironically, I had more spring slippage on the second side, but that didn't slow me down as much of the fear of that happening on the first side slowed me. Interesting.

Anti-Sway Bar
With the rest of the suspension put together, all that's left is the front (anti-) sway bar. In my searches around the internet, all of the articles I found about replacing the sway bar had the classic "install is the reverse". That is not helpful, so I'm documenting what I did that worked. If you're using your original bar, clean it up and paint where it's been chipped when you're doing your other parts. It is so much nicer, and the bushings go on much easier. We start with those bushings. The graphite-poly bushings are a solid trapezoid, so you will need to cut along the seam so it will wrap around the arm. I tried sliding it on from either end, including removing an arm-end, but that doesn't work. You have to cut it parallel to the path the arm would take through it.

Get the bushing onto the bar. This can be hard, but with some window cleaner (or plain water) as a lubricant, and a little force, it pops on. Use the little locks on the bar as a guide for where they should be located (just to the outside of the lock/clamp). Now test fit the bar with the new brackets. For the MG, there are 2 small black pieces of steel that hold an air deflector that need to fit between the bracket and the frame. Just test fit that it will roughly fit and that the bar is pointing the right way (ends pointing rearward).

With the brackets now removed you're ready to start the install for real. Hold the bar in the rough spot where it was during the test fit and wiggle one end of the bar into the lower control arm. Since nothing is preventing complete movement, this should be relatively easy. If the sway bar end is not making it through the hole no matter what you do, you could be experiencing a manufacturing defect in the arm. I had this happen: the rearward hole was too small for the sway rm end to pass through. I had to widen it with a drill.

Once the first one is through both holes so a bunch of threading can be seen/felt on the rear side of the control arm, switch to the other side. You may need to work kind of hard to get the second side in. I did. Lots of pulling and pushing before the bolt passed through both holes. Set the ends all the way in with a couple of whacks with a hammer. Place on the lack-washer and the 3/4" nut, but don't tighten it all the way down. Now shift to the brackets, the metal thing, and the bushings. Thread in the 2 pairs of 1/2" bolts, but again, don't tighten. Now, push/pull on the bar left and right to makes sure it is centered and there isn't any torque holding it out of center. Now, tighten the bolts and nuts down. Again, I recommend new fasteners.

Now, we can lower the car. I set the jack under the rear edge of the front beam, lift the car just enough to get the stands out and set the car down. After so many months of the front being in the air, it really looks kind of weird. Really low. For fun, I jumped up and down on the front bumper. Where there used to be considerable bouncing both on the initial jump, but in aftershocks as well... the MG barely responded to my jump and didn't bounce. It just returned to it's ride height. So tight. Once I get back on the road, it is going to hold the road like a brand new (or better) MGB.

That's it for today. This has been an incredible marathon, but feeling the difference bouncing on the front bumper tells what it will be worth. The front end should be in solid operating shape for another 40 years. Thanks, as always, for following along. I will get the festival review, the bus improvements, another road story, etc. posted as I can get to finishing the stories.

MGB - Front Suspension Refresh (Part 3)

I'm continuing the front end rebuild I started in Parts 1 (See MGB - Front Suspension Refresh Part 1) and 2 (See MGB - Front Suspension Refresh Part 2). At this point, the front beam is stripped and removed from the car. We've evaluated the parts, and made determinations about which to keep and which to replace. Today starts the work of putting it all back together again. WooHoo!

Pivot on the Swivels
There some things really are best left to a shop. I want to do as much as I possibly can myself, but it's not a religion. It's just a strong preference because I want to learn and because I find it fun. I read through the process for removing and replacing the king pins and bushings within the swivels (wheel assemblies). This requires a shop press, which I don't have nor do I have the space for, and a trained eye for determining the viability of the wheel assembly as a whole. So, I contracted the fine folks at British Auto Works to do it. Like so many things, I expanded the job from just swapping the king pins and bushings to also include replacing and grease-packing the wheel bearings. Doing the wheel bearings didn't really increase the cost, and it gave me the peace of mind that the entire front end had been updated. British Auto Works completely strips, and then chem-tanks all of the wheel assembly. after testing and measuring everything, they assemble the wheel and finishes the job with fresh paint. All told, it took them three days, and most of that was because they wanted extra time in the chem-tank. The finished product looks fantastic and delivered that piece-of-mind that they were properly done.

Paint

While the swivels were at British Auto Works, I started working on the beam. For being exposed to the elements, and road debris for almost 40 years, I would have expected more damage or rust. In truth, it was in pretty good shape. So, I cleaned it up, first with a power washer, then by hand with Simple Green. Once cleaned, I could see a few scratches, but it was in really fine shape. I threaded the rusty old bolts which held the front shocks back in. I did that so paint wouldn't gum up the threads. Then I sanded it, wiped it down with mineral spirits and shot it with high-gloss black paint. Since I had the time, I let the paint cure for a week, light sanded it, wiped it down and shot another coat. At this point, I removed the old shock bolts so the paint would cure without them. While I had the materials out, I cleaned up the spring pans and springs, sanded and painted them too. Truth be told, I had lots of other parts around that I intend to re-install, so I cleaned them up, sanded, wiped and shot them too. I'll share some of the tear-down and re-assembly of those things in other posts. Everything got high-gloss black except the springs. Those I shot burnt orange which from afar looks like the vermilion on the body, but its not an exact match. I decided it wasn't a deal-breaker so I also sanded, wiped and shot the underside of the frame where the front beam mounts to it. I figured I wouldn't have that exposed again any time soon so why not?

Beam Me Up

Once the paint has been shot and cured, I was able to start assembling things. First, was the re-install of the bare beam. Since I was working on this by myself, this was a great deal harder than the removal. Why? The beam is held on with 4 bolts. Each bolt has a nut on both ends, and it passes through 2 poly/graphite (or rubber of simply poly) bushings, one on either side of the beam. The drawing on the side, here, with parts labelled 1 through 7 show the front bolt. The rear is similar. Note the orientation of the bolt in the drawing: the lump is on the bottom. This is important since the thinner stretch of the bolt runs up into the frame. If you try to send the lump up, it will not make it through the frame. Yes, I did try it that way. If you're doing this on your own, I fumbled my way into a process that works:

Get the beam onto your jack, and roll it under your front bumper. Looking from above, roughly align the rear of the beam with the rear frame holes, but still a few inches below it.
Pick a side. It doesn't matter which. Take the shorter, rear bolt, and load the bolt, stacking from the bottom: nut, plate, bushing. twist the nut onto the bolt a few turns. Slide the bolt up through the rear hole from the bottom of the beam, placing the top bushing onto the bolt. I found that these bushings sort of held the bolt in place.

With the bolt held in with friction, get more precise with your alignment, but just worry about that one hole and bolt. Raise the jack and re-check. Repeat until you have the bolt and hole lined up. Then, while holding the bolt to the beam, raise the jack, pressing the bolt into the frame. Once the bolt peers through the top of the frame, put the top nut on. Again, thread the nut on just a few turns so the bolt can hold the beam, but there is still a couple of inches between the top of the beam and the bottom of the frame.
The one bolt creates a pivot point so you can align another hole. I did the other rear bolt, following the same routine. With the rear bolts loosely in, the fronts are much easier. Stack the front bolts again from the bottom: nut, plate and bushing. Set the upper bushing, and set the bolt through the frame hole. Thread on the top bolt.
Now you can start tightening the nuts. On all 8 nuts you want some threads to peek out from the nut. If you don't see threads, you may not have enough bite on the nut to withstand the pressures during intense driving. Then, torque to spec (54 to 56 ft/lbs).

Shock Me

Once I had the beam in, I shifted to installing the front shocks. If you remember, the removal was only difficult for the rear bolts because of how close they are to the wheel well. The install is also challenged by this. If you painted your beam, did you paint with the bolts out? I accidentally left one out: the one I took to the hardware store. That bolt hole was a real pain to get a bolt into at this stage. The others just took a little windex on the bolt, and it threaded right in. Once finger tight, it doesn't take much to torque it down... except getting a torque wrench in there is impossible. You'll need to feel it, as you're aiming for 43 to 45 ft/lbs. I actually came back and torqued after I did the lower control arms because the torque settings are so close, I got a good feel for what 45ft/lbs is supposed to feel like.

Lower Control Arm
Now for the fun part. Whether you bought new arms or cleaned up your originals, there are two different arm shapes: one for the rear and one for the front. The "front" has a hole specifically for the sway bar that's reinforced. Pick a side. Grab a spring pan, three sets of spring pan fasteners (1/2" nut-washer-bolt combinations) and your lower control arm bushings. If you got the fender washers like I did, grab them too. You don't need the lower trunnion kit nor the spring yet. On each arm, press in the bushing. If you got the poly bushings, this may require a press. The rubber and poly/graphite fit in without much difficulty.

Slide a fender washer onto each front-back side of the pivot (the thing on the beam that the lower arms attach to). Then fit the rear and front arms on that same side, making sure to have them pointing towards each other and making sure you're using a front and a rear arm in the right spots (rear on rear, front on front). Yeah, that sounds obvious and all, but once you get on the ground all those arms start to look the same. Consider that the flat side on the arm faces the pan (see the picture).

Let the arms hang down and grab the spring pan and one set of fasteners. Holding the pan with the dish facing towards you, lightly thread the bolt through from the outside of the arm through to the pan. Set a washer on the bolt and then finger a nut onto the bolt. Do not tighten yet. Do the other 2 fastener set the same way: 2 on the rear, one on the front. With the spring pan loosely held to the arms, slide the other fender washers on and follow with the castle nuts. Once everything is on, but loose, start tightening things, moving from castle nuts to spring pan fasteners so no bolt gets hung up because it has been left untouched for too long. When everything is snug, torque to spec: 22 ft/lbs for the spring pan fasteners and 45 ft/lbs for the castle nuts.

For the castle nuts, align the castle with the cotter-pin hole and put in the cotter pin (or bailing wire, if you're like me). Better to torque a little too much than not enough, IMHO, but you shouldn't need to go higher than 50 ft/lbs. If you do, re-check your work. Maybe something is hanging up.

That's it for this time. I should be able to finish this up in just one more post. I'll get the swivels and springs on, and then the major efforts are completed. Thanks for following along. This has been an incredibly rewarding effort.

MGB - Front Suspension Refresh (Part 2)

Continuing from my last post, I'm focusing this group of posts on the rebuild of the MGB front end. Today, we get down to the beam, and get it removed from the car. I'll evaluate parts, and talk about replacement bushing options. Part I can be found here.

Shocking
While the beam is in, and you have access to your front shocks is the best time to evaluate them. On the right side, the shock responded relatively well to my efforts to move the arm up and down. It resisted in both directions, but not as much as I would have liked. Still, I probably could have left it alone. The shock on the left (driver) side, however, offered virtually no resistance to my attempts to move it. In fact, I could push it to the top of it's motion and it would slowly drop down. That shock is shot. Suspension shops usually recommend replacing both fronts and/or both rears at the same time. For a front-end like this one, where the shock absorber is also playing the part of the upper control arm, it is all the more important. These are held in place by 4 bolts. The two against the inner wheel well can be difficult to get to, but you can address them with the most basic spanners and ratchet/sockets. Similar to the engine mount replacement (see MGB - engine mounts), a good supply patience is welcomed here.

Set the shocks aside with the lower arms and pans. To protect the threaded holes, finger the old bolts back into the holes. I took one with me to Orchards and found replacement grade 8 stainless steel ones for the reassembly. I strongly recommend replacing fasteners with stainless steel or zinc coated to reduce the rusted-on effect.

Beam Down

image swiped from 'net,
but that's a stock beam

Now, the front beam should only be connected to the car by 4 bolts. Nothing else should be tying them together. No brake lines, steering bits, etc. but it never hurts to stupid-check (so-called for those moments when you don't check, something bad happens and call yourself stupid for not checking).

I used an ATV / transmission jack, but a more standard wheeled floor jack should work; it will just take more patience with balance. The ATV / transmission jack is nice in that it has two long arms to spread the weight, and improve the balance. Still, with the front end way in the air, and the rear on the ground, the bottom of the beam is not parallel to the floor. So, I slid a 2x4 under the front of the beam when the ATV / transmission jack reached the underside of the beam to make uniform contact. Raise the jack until it is holding some weight, but not much. You want the car stable on it's jack stands.

Relieve the torque on the 4 bolts by cracking the 4 bolts on top. you shouldn't need to hold the bottom nuts at all for this. I used the breaker bar with an assortment of extensions. Once cracked, do the same on the bottom nuts, just so they are not rusted in place. Whether you remove the nuts on top or the bottom or a mixture doesn't really matter. In the end, all 4 bolts need to be un-nutted on both ends. You would think that once the nuts have been removed from the bolts, they would just fall out. Fat chance. How about lowering the jack a little bit? Nope. To free the bolts, the top nut needs to be removed. Then, using a socket extension so you can address the bolt, rap the bolt from above with a rubber mallet. When this doesn't work, use a framing hammer, but be very careful with those bolts. They are not normal and if the threads are damaged, you'll need to order new ones.

Once the bolts fall out, either through banging or playing with your jack or maybe you got lucky and they just fell out... you'll see that these bolts are 2 different lengths and that the longer bolts (that fell out of the front) have a lump in the middle like a poorly rolled spliff. I retained all of this hardware, choosing to not try to find replacements, though I thought about it. Simply lower the jack, and the beam will lower with it. Pull out the front under the radiator and bumper.

Parts and More Parts
At this point, I was pretty spent. From the start of the prior posting to the beam on the ground was at least 2 days. Now that I've done it once, though, I could do it again in 1/3 of the time or faster. As I set with a beer, I looked at the pile of parts and the zip-lock baggies of fasteners. The fasteners were all bare steel, and they had plenty of rust on them. I chose to replace all of them except the beam-to-frame nuts and bolts. I added 4 fender washers to fit between the beam and the lower control arms. I felt this would help the bushings last longer. The fasteners probably put me back $50. Then, I turned to the pile of parts:

front shock absorber /
upper control arm

Front Shock Absorbers (2) New, these are crazy expensive. Moss has them for over $330 each. Instead, I found World Wide Auto Parts in Madison, WI who rebuilds originals. After some research I bought a pair from them at $99 each plus core which was returned when I sent my old ones back to them. They really look great, and if they work as well as they look, I just may go back for replacements of the rears instead of doing the swap-out for non-MGB rear shocks that so many folks do. The paint chips off without much effort, so if you're going for a show-car experience, I'd recommend repainting them.

Lower Control Arms (4) These looked okay, but without tight tolerance measuring tools, I couldn't tell if any of the important holes on the ends were out of round. Replacements for all 4 was $70 with OEM British steel, and the originals could have been worn from the bad seals, so I coughed up the $70.

lower control arms

Spring Pans (2) Like the arms, I couldn't tell for sure if the mounting holes were out of round, but on very close examination none of the holes looked oval. Since no pivoting happens with these pan holes, even a little out of round probably wouldn't matter so I chose to keep the spring pans, and just clean them up instead. New-steel replacements are $32 each at Moss, so they're a little steep cost-wise compared to some of the other bits. Still, if the spring pan won't firmly attach to the arms, your suspension won't be safe, so spend the $64. In the end, there was 0 play after everything was put back together, so my assessment was correct.

Front End Rebuild Kit (1) This was the whole point of this work. I found a few different suppliers for this kit, and resolved to buy from British Parts Northwest for $120. While their return policy is crap, their price is $35 less than Moss. These kits include:
- king-pin set and bushings. These run vertically between the arms and through your swivels
- upper control arm nut/bolts. They call them "fulcrum pin and hardware" and they attach the top of the swivel to the control arm / front shock absorber.
- upper control arm bushings (rubber or all-poly). These pair with the upper control arm nut/bolts to complete the set. I ended up swapping out the kit-supplied ones with some Poly/Graphite bushings I got from a new friend, Basil, in California ($6)

- lower control arm to swivel bolt/nut and bushings. They call these "Lower Trunnion Kits".
- lower control arm to beam ("A-Arm") bushings and bolts (rubber or all-poly). Again, I went with Poly/Graphite ($20) from Basil instead of the kit-supplied ones.

To do the front end rebuild, that's really all you need. I decided, though, that as long as its open, replace the beam-to-frame bushings.... and the sway bar bushings. Again, I sourced these from my friend in California. frame bushings ran $23 and the sway bar bushes were $10. When I consider there was no extra labor for the beam bushings, and very little on the sway bars, this was a very low cost to get the front end as rock-solid stable as possible.

Rubber, Poly and Poly/Graphite
Just for an aside, I wanted to touch on the differences between these three types of bushing. As a general rule, it's best that you pick one and stick with it through the front end. Since they behave a little differently from each other, the front end could be less predictable if your lowers and uppers are not the same material and respond to stresses differently.

Rubber - this is what you had originally. When squeezed between two pieces of steel which want to twist, the rubber twists with it. This smooths out the twisting motion, giving an easy, forgiving ride. For a cruiser, this is great material.

Poly - this is the more common "upgraded" bushing. Unlike the rubber, the poly does not twist with the steel; it resists the twisting motion. This resistance reduces the degree of the twist, allowing more of the force through to the ride. This is a much less forgiving ride, but gives you a much stronger "sense of the road". Installing these bushings can be very difficult, requiring water-based lube or other tricks, maybe the use of a shop press. Once installed, most owners report loving them.

Poly/Graphite - this is in-between the Poly and Rubber in terms of road feel and difficulty of install. Basil described this far better than I could, so I will quote: They look like black plastic that has some give to them. You can put one between your thumb and forefinger and feel it give a little. The polyurethane matrix has a slippery substance called "graphite" (a crystalline form of carbon) in the polymer matrix so a slippery bit is always exposed and thus self-lubricating the bushing. No special install efforts needed.

This post got long again, so I'll continue in another post. At this point, we have the front beam completely torn down, our parts are ordered, and fasteners sourced at the local hardware store. We'll start next time with some painting and then assembly. Thanks, as always, for following along...
