I have been trying out that Harbor Freight Front Wheel Bearing tool.  So far
it works for me for front wheel bearings, but the 20 ton press is faster.  I
don't think I have done many rear wheel bearing that require heavy duty
tools...............yet!  ;-)

Front suspensions are interesting on the A4s too!

I have never had that much problem with any bearings I have removed for the
last forty years!

Go Audi..

Strangest looking rear assembly that holds the bearings too.

Looks like it was designed by someone that was fascinated by chicken parts.

It just did not want to leave willingly, it left kicking and screaming huh?
lol

glad you succeeded!

Yes on the Rust Penetrate.
As far as tough to remove, the 12ton press broke trying to remove them.
The 20ton complained, but then the bearing finally gave way.

In a pinch I have used a heat gun to help warm things up a bit.  It has
worked for me a couple of times.
This is when I did not want to use the blue wrench.  I just have to refill
my tanks.  ;-)

Are the rear bearings that hard to do?  I have done a rear wheel bearing in
a 1990 Audi V8 (IIRC) and don't remember it being that bad.

Did you use some Rust Penetrant?

Broke down and bought a 20ton. 12ton broken. 20ton made that bearing squeal,
then bang, and it popped out.
Really didn't want to torch it.

What is the trick to removing the rear wheel bearings? 12ton press does not
begin to press it out.
Was able to press the hub out. Just not the bearing.

Torch to me, is the last resort.
