[urq] Early urq control arm bushings - 811 407 181 vs 811 407 181A vs 8a0 407 181

[Martin Pajak]

Louis-Alain,

I think you are making a bit of a mistake.
You are comparing apples to oranges.

Your's and Eric's car have different control arms, hence the different
part numbers.  These bushings are not interchangable.

The early control arm bushings do not use steel shell and look like
dumbells (both sides have higher sections).
Installation procedure is here:

The later style stamped/spot welded control arms use bushings with steel
case and only one side with raised section.
Installation procedure is here:

Hope this helps.

> So, use the 857, you just have to know that they don't last as long as the
