I've got a Aubrurn diff in a 71 GS455 with an 8.5, and it's doing something funny. The car runs 12.7's with a 1.83 60 foot, and sometimes when the car spins at the line, the diff seems to lock. The run goes fine, but when I take the tight turn off, the car gives a big snap and the rear jumps a little, kind alike a locker.
Has anyone hear ever experienced an auburn rear temporarily locking up? I know it's a little worn, sometimes on the burnout the left wheel gets a little lazy.

Re: 8.5 Auburn Diff
You will need to open her up. It may only be a heat issue and in the turn it grabs from too much heat from the run and brake torque at the starting line or you have spider gear issues. Jim
