GTI Rear Shocks - Part 1
Yes, you read that right. I've stopped moaning about it and sucked it up and got to work. I decided a Friday night after a particularly long work day that left me tired and cranky would be a good time to start a car project. And my wife and kids left for her parents cabin this morning... and I am supposed to join them tomorrow... in my car I am about to take apart.
My only impact is this Menard's Masterforce hex bit driver. It's more for driving decking screws and the like. Not very powerful so I use a breaker bar, and this to zip things out. Would be great to have a real 1/2" cordless impact.
This is actually the first time I've ever had the car on 4x jack stands. Normally for oil changes I back onto ramps, and just put the front on stands. Or just lift one end for wheel swaps, etc. It took a little figuring out but it went well.
Removed the knuckle and strut bolts with a breaker bar and ratchet. The deep socket slipped off at one point and my hand slammed into the floor jack I had below the control arm (not pictured), gave my thumb a nasty bruise. Swear words were flowing.
Typically the sway bar end link bolt would also come off, but since I am keeping the existing lowering springs, I found I was able to finagle the shock out without removing that or disturbing the spring.
To get to the upper mount I had to remove the fender liner, which was held in by about a billion Torx T25 screws. Classic VW move. Just when you think you've got them all, there's one more.
The shock mount bolts were a bit rusty and at an awkward angle, but no real trouble.
Inspecting the OEM shock, it's a bit beat up. Some paint flaking, some rust, the rubber bushes don't look great.
And now for the fun (read:
not fun) part. I came to the realization that I did not have the tools to get the shock top nut off.
Now, I did notice the flat tab and nut on the new ones, but the new ones don't have the mount (gotta reuse that). I watched a lot of YouTube videos to prepare myself, but
most people in the videos are installing coilovers, which don't use the stock mounts, or have a different allen key system. Or they are just installing lowering springs and keeping the stock shocks (which I did originally), and don't show the stock strut disassembly process. So I didn't know the nut was recessed like that. And the one video I did find that showed it (ShopDAP) use air impact, which is probably not "proper".
I'm sure the car guys know what I'm about to say, but for others new to this like myself reading along, the nut spins the whole shock assembly/rod unless you hold that tab from moving. The proper way to do this is with some specialty tools (a passthrough socket, hollow ratchet, special key that holes the tab inside the passthrough socket, and an additional wrench to hold that key. Looks something like this:
Of course I have none of that. And did not know it at the time.
So... went inside to do some research (it's around 9pm now, pouring rain and dark outside). I couldn't find the needed specialty sockets and wrenches in stock anywhere that I could immediately pick them up. Except
this pass-through set at Harbor Freight. It's not quite meant for it, but I saw it mentioned on a VW forum so I'm going to bring the old shock assembly and see if I can test fit it. The tab would need to protrude out the top of the passthrough socket so I can grab it with some vice grips. Another possibility is a metric deep offset wrench set + vice grips. I'd need to buy that, too. Won't be able to get a torque wrench on it, but I don't know how to solve that.
I didn't put the car back together because it got too late. My dad is going to drive me to Harbor Freight first thing in the morning to see if either of those "hack" options will work. If not, I'll have to put it back together with no progress so I can hit the road to Wisconsin.
So... here she sits for tonight. If anyone has any other wise ideas that I could implement by early afternoon tomorrow I'm all ears
I have a feeling that when this is all said and done, including the fronts, I'm going to be wishing I had just paid the shop their exorbitant asking price
To be continued...
