I don't want to take over this thread from 66... but
Just wondering about care and feeding of these rear ends. Haven't had my truck very long. I just changed the Diff oil yesterday, using Valvoline 80/90.
Is it enough to just change the oil every 10,000mi like the book says? Any advice on getting the most miles out of one of these rear ends?
Also: Do the labels "Positraction", "Limited Slip", and "Locking" mean the same thing?
