I'm not sur why your carrier bearing can't be replaced separately. Drive
shafts don't tend to rust-out. I paid $45 for a new bearing for my
Ur-quattro if anything the one for your car would be even cheaper
(although if you are paying for labor the difference is not so great) I
bought my bearing from TIOGA driveshaft exchange in Pa. 1-800-435-3010.
Anyone who has ever bought parts for a Ur-q will tell you how extremely
reasonable $45 is for a part such as the carrier bearing. You get only
the bearing (no rubber mount) and instalation is not easy. Everything
must be marked before it comes apart so that the shaft will still be
ballanced when you put it back on the car.
I did mine with little difficulty, however I have a fully equiped shop
with a lift. I had no ballance problems, but after I bought the bently
manual I noticed that Audi says the job can not be done without some sort
of driveshaft alignment tool. Since I put everything back together
exactly the way it came apart I had no problems (especiatlly critical is
the mounting of the carrier to the body). Quiz your mechanic and see if
he knows anything about the concept of driveshaft alignment. If you have
to pay for the job you might as well get it done properly. So in other
words you may want to pay a few bucks more and go to someone (such as
your dealer) who really knows what they are doing (suposedly).
Rebuilt or new driveshafts are very expensive (imagine what they cost
for a Ur-q) which makes a $45 bearing at least worth a try...
Hope this helps...
