Collage of differential parts, including gears, a sensor, and a…

After a few good drives without problems, I swapped the rear diff cover to the later cast Aluminum version Dorman 697-725, which required longer bolts. The oil looked better than any I've seen, with almost nothing on the fill magnet, and nothing at all on the ABS sensor. It takes nearly a gallon of 85W90 gear oil and 8oz (2 bottles) of XL3 friction modifier because it's a limited-slip diff. RightStuff is very good & easy to use, but $$$. UltraBlack is nearly identical, but costs less.
