Upper Mounting Bolts
I am like Alan, I can't beleive 3 of the 4 upper mounting bolts broke....
I can't beleive you could break 1 of the 4 upper mounting bolts, I don't think were talking about the same think here. I think it was the four bolts , 2 on each side that go into the side of the differential that are normally safety wired. The originals were grade 5 and tapered, the upgrades are grade 8 with a tapered sleeve. And the reason these original bolts broke was because the lower plate that most people have to tie both sides to the differential was not in place.
