So having attempted to change my sons rear discs and pads on his 2004 3.2 A3 quattro, gave up due to the carrier bolts being stupid tight.
The noise from the rear of the car is, a grinding scrape nose, speed related that sometimes disappears. ? I wondered if it was his worn discs however the pads seem fine , I tried rotating the wheels . 1 by 1 to replicate the noise without success. Is it likely to be the diff?, or cv joint. It is not very loud, however seems a bit disconcerting. Any suggestions on where to proceed would be appreciated.
Thanks in advance Alex.
