Car Ports and Car Noises

What a difference a week makes. In my last post, I mentioned that I had helped T moved some stuff out of the one garage bay. Since then, K got the rest of his stuff, so Oliver is back in the garage. Also, the 2 carports from Harbor Freight arrived. So, I quickly moved from all cars out in the open and no sheltered space to work to 3 cars under some kind of roof, creating all kinds of work space. So, today's brief post if about getting the car ports up, and some diagnosis into the noises coming from Nemo.

Car Port Assembly x2

400 sqft of not raining

I have a small 2-car garage. I underscore small because Oliver (1978 MGB) barely fits between the garage door and the walkway along the opposite wall. Considering the MGB is one of the shortest cars out there, I couldn't imagine parking a Caddy or one of those big pickup trucks. Simply put, it wouldn't fit. So, when I think about how I'm going to complete Zed (1979 280XZ) this winter, I shudder. It's way too small to shoot paint, and with the gas furnace in there, I couldn't paint while heating the house, so the plan unravels fairly quickly. So, I got a couple of those 10' x 20' car ports that Harbor Freight sells (~$120US each). My driveway has a slight tilt towards the garage, but it's otherwise fairly flat.

V between

While I would have preferred a purchase ship-to-store option, the harbor freight website doesn't offer that. Instead, they offer $7US to ship it by FedEx Ground. That sounds like a cost-loss on their part, especially for a pair of these car ports, but they arrived before the primer from Eastwood (which still hasn't arrived). The assembly is actually very easy. The instructions have only a handful of steps and the exploded drawing is not as bizarre as IKEA furniture. I used a rubber mallet to get the pipes to fit together quickly. I was able to get each one assembled in about 2 hours, measured from when I walked out my garage door with a full box to walking back in after set-up and recycling/throwing away the packaging.

I set one over the top of Zed, and the other right next to it. I would rather not have a 20' dripped seam between them, and pushed the posts right next to one another. I took the 8-inch-or-so hangdown from one, and flipped it up over the top of the neighboring car port. The other hangdown, I pulled across and clipped to the tie-down seam, which runs along the inside, above the bottom rail. Then, I forced the pipes together and cable-tied them. This created a small V shape of car port tarp between the rails, running all the way front-to-back. My plan is that this will direct the water down to the lower end of the carport. I think this will work except for those super-heavy rain events we get sometimes. We'll see.

A4 Front Clunk

top of front strut, example

Now for some car content. After getting all the little things fixed on Nemo, I took him for a short test drive to see how he felt. He felt pretty good. Lots of boost, and plenty of power, but he made lots of noise. I could hear a clunk pretty much on every little bump. I figured it was the sway-bar bushings and replaced them: 13mm bolts hold the clamps on, and the bushing has a slit in it so you just need to remove the clamps, pull off the old bushing, slap on the new one and put the clamp back on. Times 2. The noise got a little better, but after pushing the fenders up and down, I believe the problem is in the strut-mount. From what I've read, after market struts that lower the front end (like Nemo has) put more pressure on the strut-mounts than the stock ones do, transferring some of the burden from the springs to the mounts to hold the front end up. This causes them to wear prematurely. So, I will be looking to replace those. Since I have a very healthy fear of strut springs, I will probably remove the struts and have new mounts installed by one of the shops around here. Better to pay with some hard earned cash than with some body damage.

A4 Rear Hum

Also on that test drive, I noticed that the rear end would make a humming noise once I got above about 30mph. I figured it was the wheel bearings, so I put the back end up on jackstands to confirm. The wheels had no play in them. None. Curious, I pulled it out of gear and spun the wheels, listening for noises (that would translate into a hum at speed). I heard clicking coming from the inner CV joints. So, that means at least removing one or both rear axles. Fun. Of course, with the AWD, I can't be 100% sure the bearings aren't bad. I may not have gotten the wheels spinning fast enough to make noise.

the diff oil fill, example

I intended to drain and fill the rear diff while the rear end was up in the air, but the fill plug is stripped. While I was under there, I got to see just how much caked on grease could remain attached to the outside of a differential without falling off. The answer: a LOT. I am really concerned about the health of this diff, and the whole rear-end, for that matter. Before I go any further with it, I will collect a second opinion. After that, I think it will have it's ass-end in the air for a while as I replace CV joints, and/or wheel bearings and fight off the fill plug so I can refresh the fluid. I'm not sure a 20+ year old 230k+ mile A4 is worth terribly much, but this is how we learn, and this could be a useful daily-driver for someone, maybe, eventually.

Well, that's it for today. I have not gotten back into the Zed paintwork since I put up the car ports. I really wanted to get Nemo road-able first. With the car ports up, I have more paint prep to do, and I need to figure out some sides for the car port space so I can heat and paint. Thanks, as always for following along-

Daily Driving

At some point after my trip to Boston, the clunking noise coming from the front end of my 2001 TDI Jetta (Flash) started to really get to me. I don't know if it was the weather changing or the car's growing desire to turn right, but I knew something was going sideways. Today's post covers that saga.

Rebuild Parts

from MetalMan Parts

I trolled around the internet and found some good pub on this rebuilding kit from MetalMan Parts. So, I hit the site, and made some decisions. First, I got the fuller kit with the TT rear bushings. While that cost a little more, I figured this was a replacement I probably wouldn't be doing again. I also got new front struts (COFAP for comfort, recognizing the TT rear bushings will stiffen the ride) and new strut mounts. I had read good things about a 1" lift kit from Evolution Import, and I got that too. A few days later both shipments had arrived.
Upon inspection, the MetalMan kit was pretty fantastic. Every fastener that needed to be removed had a replacement. They sent both sway-bar bushing sizes and replacement clamps. It looked great.
The Evolution Import kit wasn't as impressive, but it looked like what I expected from the instructions online. It was shiny and relatively simple. I ended up not putting the rear lift in, and the Jetta sits flat with out it.

Destroyed My Arms on My Arms
I set aside the weekend to install everything, with the recognition that I would need to take the strut assemblies somewhere to get the springs moved from the old set to the new set. I'd also need to get the alignment done somewhere. Otherwise, I felt I could do everything else. 9:AM Saturday morning, I pulled Hapy out of the garage bay where he'd been resting since our active Summer and put Flash in his place. By 11:AM, his was on stands, the Panzer plate was off and I had my plan of attack. I'd start with removing the control arms. Once the old ones were off, I could easily get at the sway bar bushings as well as get the struts out.  The sway bar links came out with little trouble, but the 2 18mm bolts with point towards the rear were a little tight. I had to work them pretty hard, and I found my arms started to get sore. But that was nothing compared to the 2 bolts which fed up from below. I tried PB Blaster. I tried a propane torch. I tried this stuff from Amsoil called "toolbox helper". I went back to the torch. By late-afternoon, it was clear I wasn't going to get either of them off so I soaked them with the Amsoil stuff and let it sit overnight.

Sunday morning, I ate well, enjoyed coffee with Boo and then went back to the bolts. Within 30 minutes, I'd concluded that the soaking hadn't helped and I was stuck. My arms were really aching from the day before, so I started looking for options. Since the front end was in pieces, I couldn't easily take the car to someone to get the bolts off, so I hit craigslist for someone willing and able to do the work in my garage. I found a father-son team, and they were happy for the work.

MobilePDX

now that's a breaker bar

MobilePDX is a father and son team who have worked on cars for years. Courtney is around my age (dirt is older, the internet is not) and has been wrenching on cars since he was a kid. They were organized, clean and left my garage in better shape than they found it. I'd originally intended to have them just get the 2 bolts off and swap the struts, but once they got going, it was just easier / faster to have them finish the job. They were able to get the passenger side bolt off with a breaker bar and youthful strength. The driver-side had to get ground down with an angle grinder. I'm not exactly sure how they got the bolt out after that. They followed my original plan from there, verifying my thinking... which is always nice.

Aw Nuts
After MobilePDX got everything back together, they discovered that the front caliper bolts were not grabbing into the hubs. Upon inspection, the threaded holes weren't threaded anymore. Neat. The proper repair is to over-drill the holes and thread in a helicoil (or something similar). That is what Courtney said and the chat-rooms agree with him. Others have used an oversized bolt that is so widely available both on the internet and the FLAPS (friendly local auto parts store), I'm inclined to think it is becoming a widely endorsed solution as well. While I sort this out, Flash sits on jack-stands and I am driving Hapy every day.

Hapy Hapy Joy Joy
I'm sure if I look back into this blog, I have many references of going back to driving the bus after a period of not driving him and expressing the pure joy of driving the bus. It really is awesome. The smiles, waves and conversations happen as much in the wind and rain as they do in warm summer. That's pretty neat.
I have continued my experimenting with the shift-point, shifting now around 3400RPM. This allows for the engine speed (when dropped into gear) to still have some turbo influence. So, he's got even more zip than the old 1700 had from the bottom to the top.
I just put 10 gallons into the tank, and I got over 28mpg since the last fill. Since there's a lot of city driving in there, I think I could have a viable city/highway mix guess: 27 city / 33 highway. Pretty fantastic. It hasn't been all smooth sailing though.

Fix-It List
On an exceptionally cold morning, I discovered that the dash vents weren't quite aligned properly. When I went to fix it, I accidentally pulled the wiper electricals out of the switch. Turns out, that bundle of wires needs to go through the hitch in the center of the plastic "Y", not around it.
After fixing that in the parking lot at work, the heat is suitable for clearing the windscreen from mist or fog, but it smells like diesel exhaust. I need to locate a source for fresh air before I drive Hapy into real cold weather.
The fuel gauge needs to be replaced. I still don't know the actual capacity of the tank and guessing based on the mileage when I last filled isn't a reliable measure. Cold wet weather isn't the time to guess if you need fuel.
I didn't re-install the door seals after I painted the top 1/3 of the bus. This creates a pretty good breeze when travelling over 35mph. I need to install them. Of course, the old ones were pretty beat up, so I need to order another set.
The bus still has some rattles, and I think one of the door skins is the main culprit for most of it. Also, the other jalousie window is now making the noise the rebuilt one used to make. Perfect. Time to rebuild the other window.
Last, the brake warning light flickers at me. This usually happens when I remove or do something around the battery. Since I had to charge the battery before moving him out of the garage, this was self-inflicted. I think there's a fluid leak near the master cylinder, though, so I may have to do a fuller brake overhaul soon. Either way, I'd like so much for the flicker to go away, or just never happen.

That's it for today. Like usual, if I'm not posting, its because I'm working on one of the cars.... or traveling. Once the front brakes / hubs are solved, Flash will be driving again and I'll start knocking down the list above for Hapy. The good times never end. As always, thanks for following along, and please pray for snow. I'd really like to get some gravity testing in this winter and our farmers need the snow-pack for summer irrigation-
