Bowing to peer pressure A body style

Last time I was at the track, I got some wheel hop and busted a tooth off my ring gear. Plus, when I took it apart, I found two teeth gone on the spider gears. For starters, check the torque on the pinion nut, but probably the center section needs to come out for diagnosis.

I drove it home like that. It was noisy and vibrated a little bit accelerating, but was really bad when decelerating.
