Luckily for me, a local Audi shop can do the swap in less than 30 minutes
for $75 including parts. I'm all for DIY work and all but there are some
things I'd rather pay someone else to do and this is pretty high on the
list...have you gotten a quote from a local mechanic?

I have done this by hand (breaker bar w/ 3' torque amplifier)....it sucks
but doable. I don't think there
is an electric or rechargable impact that can handle doing wheel bearings.
If this is your 1st one....bribe someone to AT LEAST watch over you while
doing it, there is lots of
points to get hung up on. Lube the screw shafts for the bearing tool.
Freeze the bearing, and the hub
(as soon as you free it from the old bearing); freezing them makes them just
a little bit smaller and
easier to insert. The inner race for the bearing will more than likely come
out w/ the hub; you a dremel
to cut part way through the race, then use a hammer & chisel to carefully
crack the race for it to slip
off...DO NOT scratch or nick the hub in any way!!!! Doing so will cause
stress risers and result in
premature bearing failure. If all this seems over whelming, save your self
some trouble and show up to a
shop w/ the entire spindle removed from the car and have them press in the
new bearing, prolly only cost
