I did those orange plastic bearings 3 yers ago, when I had to replace the torn rubber strut boots.
At that time I had the struts out of the car.
BTW, although the bearings are cheap ($12 ea), that was done in vain. They never go bad.
I had done it on my 2 Audis, and in both cases the old ones were perfect.
I would never do them again - it's unnecessary.
On a VW it's the whole other story. My wife's Fox consumes them routinely.
On a VW the bearings are combined with upper strut mounts.

No, see above.

Yep, thats the way to do it. I made my own, similar to the VAG tool.
1. Do_NOT_jack the car up!
2. Mark the position of the camber plates with a scribe BEFORE you undo those 2 locking nuts.

I don't rent or sell the special tools, that I ocassionaly fabricate. But you are welcome to
borrow anything, under the condition that I get it back as soon as you are done with it.
You are ways up north from me. If you ever come down to Philly, just drop by and get the tool.

Yep. Just have them shave 0.5mm (0.020") off each of 6 sides.

> What nuts are they?

They are made out of a pretty hard steel. The top portion of the tread is jammed into ellips.
The first one walked on me when I tried to take all 0.5mm in a single cut (you know, it's a nut,
does not have to be pretty.)
Don't do it on a nylon insert lock nut, you'll cut the casing open and the insert will fall out.

> What did you use to make the actual sleeves?

Regular steel. I used the first round stock, that I stumbled upon on the racks in the machine shop,
that had the closest O.D. and I.D. to what I was looking for (I think it was 5/8" O.D. by 1/2" I.D.).

Correct.

Gary, you forgot :
5) enlarge the top metal washer (under the top mount) mounting hole by 2mm to fit the new stems.

None. I am too lazy to use my full blown AutoCAD-12, when I can get away with  using the
Top Mechanical Layer in Tango with almost the same results (for my perposes anyway).

I'll fax it to you Monday AM.

See the fax.

Yes, but they were the wrong ones, + you need to have 4 spacers, 2 per side.
You'll see it in the drawing. Just fabricate the sleeves per my word, you'll see what I meant
when you have the old and new shocks layng side by side on the bench.

It's a 3/8" drive deep 18mm socket.
It's O.D. is 24.44 mm. The remaining wall (after the window had been ground in) is 10.85mm.
If you stand the socket with the square hole up, the window starts 18.33mm from the bottom and is 32.34mm 
long.
the total length of the socket is 64.55mm.

You don't have to be this_accurate, I am just reading my $200 digital Mitutoyo caliper.
I ground the socket by eyeballing it (1 kilometer as we used to say in the Old Country).:-)

Yep. You're absolutely right here.
Just don't remove the shock_AND_the lower control arm simultaneously. The whole assy will fall out on you.

Sure. You pay the shipping both ways.

HTH.
