The input shaft bearing feels very good and the diff is in great shape, with no leaks. I have cleaned this unit to look as it does in the photos. The rear cover was removed to inspect the ring and pinion gear and inner workings for abnormal wear so you will need to seal it when you install your cover. The ring gear and spool are quite clean. The case has minimal rust, common to CA cars.This is the real deal - no gunk or residues, suggesting this is a well cared for diff, with the oil changed according to BMW recommendations. Be assured, this diff is in great shape and will not whine! It takes experience to evaluate these units, so you can trust my description. The unit weighs approximately 90 lbs when boxed up.
Thanks for checking this out, and good luck. Powered by SixBit's eCommerce Solution.
