OK, just started working on my Challenger for the long weekend.
I started by inspecting the rear wheels because I thought that the rear oil seals had gone bad. I had gear oil coming out the brakes at the car's first autocross.
Rear end is an 8.75 with 741 with 3.23 SG. I changed out the 741 with 3.23 open.
My method was pulling the axles, R&R'ing the pumpkin, and reinstalling the axles. I had no problems until I brought the car out to the AutoX.
So today, I looked at everything and the axles wiggle 1/4" in and out of the housing. I took out the passenger side axle to inspect it, and nothing looks out of place, but obviously, something has moved. The adjuster cannot take out the slack.
Right now I'm postulating that the press fit on the bearings and backup collar wasn't enough for the autox and they've slid down. I could press them down again (I have the press and could do that) but I don't know how far, etc... Also, this problem may (will, probably) return, so it'd be nice to kick it in the butt now.
So the question is, what now do I do? Bring the axles to a shop? Bring the whole car? I'm in a quandry, and I'm pretty lost.
