Audi does not mean for UrS driveshafts to be serviced, nor repaired. Audi does not provide individual parts of the driveshaft, but rather asks that you replace the whole thing, if anything goes wrong. Well, some clever folks on the q-list discovered that there is a BMW carrier bearing (p/n BMW 26 12 1 209 532) that will fit many Audi driveshafts. Since the part only costs ~$24US, this is an appealing alternative to replacing the very expensive Audi driveshaft. So, does the BMW part work on the S-Cars? Well, maybe. It does look like it will work, but it IS NOT a bolt-up proposition. It looks like a custom bracket will need to be fabricated in order for the carrier bearing (CB) to mount properly.
