One of our customers had a loud diff in his Q4. I installed a good LSD used unit we had in stock 4k mi. into a 2018 Q4 with over 60k mi. Jet black oil came out, and that was after an oil change around 50K. After swap I dismantled the old diff to inspect the whining/growl it had. R&P had a bad pattern( hard to say if set up was bad or the LSD clutch material contaminating the oil caused it), bearings seemed fine. The clutch pack definitely had wear, I think it was stacked wrong from the get go. One clutch was against the sun gear cup directly. Swapping out third member is not to bad overall.
