They didn't do anything, ever thats why the pinion bearing smoked and ate the carrier. Super common, especially with crush collar diffs.
Hey gnob, would mind expanding on your comment a little bit? In all my years of wheeling (20+) the number of differential failures I've witnessed, or was a topic of discussion with my wheeling buddies that I was privy to, I can count on 1 hand - AND as I remember the crush collar had zero to do with the failure... probably just my lack of experience?
Is a Toy diff a "crush collar diff"? If if is, is it "Super common" for Toyota diffs to fail?
Just curious.
Gnarls.
