[s-cars] Wheel Bearing tool?

Thanks for all the hints, Kurt.  We thank Dave for confusing things
some for asking  the C4 guys about his B5.  The URS4/6 doesn't
use any clips to hold the wheel bearing in place and perhaps
because of that I find the bearings take a lot of force to press in  

The audiworld tech articles all have the guy taking the hub to a shop
to press out something.  I just don't like the idea of spending a couple
of hours on a job after buying a special tool set, and then finding it
doesn't work and I have to pull the strut anyway and use a press.
Mind you, I don't like to pull the strut tower on the C4 since that
introduces it's own set of problems for re-assembly of the control
arm and sway bar, but I am totally against hammering on the
bearing housing or hub in any manner.  I particularly like the part
where the "bearing came apart, but I just stuck it back together".

I have seen the original bearings last for 200K so maybe my need
for the tool is past.  One will have to howl loudly to get my attention

Baum tools has their own version now with a lot more pieces than
the generic Harbor Freight  version so the use is becoming more
mainstream.  If it will cleanly do the job it is certainly worth it to a
shop but they need a rental program for me.
