Changed my differential gear oil today, 11k miles, rear was jet black but front wasn’t bad at all, no metal on the drain plug magnets but a tiny bit of of grey sludge was there. Overall very easy to do, used Royal Purple 75w-140 in the rear and then finished the bottle in the front before topping off with 75w-90. After adding the friction modifier in the rear I used less than 3 1qt bottles total.
