Rich,

See the write-up under <urs4.com > transmission section about a 
replacement bearing.  Since Audi does not provide any repair parts for 
the driveline, they have to be sourced elsewhere.  Darin has the 
bearing at parts direct on <s-cars.org >.
It is not a straight R&R job-requires a little fabrication-but not too 
difficult.
