rear wheel hub

[Tony Hoffman]

The design of the bearing is such that hp, suspension, etc do not have a
significant impact (no pun intended). BTW, the first A4 out here in the
states was teh 172hp 12V V6. HOwever, there were A4's with as little as
115hp overseas.

However, if you pull the seals, you will see the reason I put additional
grease in.

On a side note, I did both rears for a friends B5S4 stage3+, four years ago
and about 60k miles now. He had been doing them at 30k like clockwork until
then. No issues since, and plenty of track driving/potholes.

We (long time Audi guys) have seen this for years, including the early
4000/5000's. Same issue, same solution IMO. Though, they don't fail as
early, generally lasting 80k+.
