Greetings- Well, better late than not at all! I finally obtained the necessary parts to convert my 2002 Audi S6 rear brakes/rotors, etc. to the RS6 version. I examined the two "knuckles" and one of them sounds a tiny bit loud when spun by hand , so I thought it wise to replace the bearings before doing the swap. Can someone point me to a source (other than Audi) that I could get a pair of RS6 rear knuckle splined bearings for a reasonable price ? I assume that the replacement bearing comes with the flange? Thank you, Paul, Providence, RI
