Default Strange 12-bolt help...

I just had gears put in my 12-bolt and after doing the recommended break-in, I took it to the track. The gears went from 3.73 to 4.10 (Richmond). The car developed a clunk when turning off the track and the next run had noticeable vibration. After putting the car up that running it stationary, you could see how bad the wheel wobbled. The was told to check for a bent wheel, and I installed my stock road wheels - wobble remains, so it is definitely in the rear end/axle.

The car doesn't 60-foot steller (1.70) but is shocked with a Mcleod ST clutch, which may or may not have contributed to my issue.

Any ideas before pulling this apart?
