we have a 1998 A4 tdi quattro which has developed leaks from both sides at the rear diff where the driveshafts go into the diff.
Has anyone tackled this ? How bad a job is it ? Can the seals be done without stripping down the entire diff?
Would it be easier/cheaper to look for a used diff rather than look at repair? So far as I can tell the rear diff is the same for all A4 quattros.
