big problem need help!!!

[moot09]

alright ever since i went to the track my cars been acting funny like about to blow up funny. First off i had a small exhaust leak right where my headers started. after the track its worse. could be a gasket? second the right back wheel seems to lock up when i make slow turnarounds. i can hear it almost drag. and after wards it sounds like itl backfire but could it be that my axles going bad?

Sounds to me like you've trashed your rear differential. Jack up your rear end and see how freely your rear wheels will spin in opposite directions at the same time. Get help if you need it. There should be some resistence, but no grinding or popping like you said that you are having. The exhaust leak is probably either a warped flange or a blown out gasket. Put your hand down there when it's idling, you should feel it puff if it's leaking. Try tightening it up, if that doesn't work, get some new gaskets and drop them in.

Trac loc pooped, may have biffed a spider gear too.

ik this sounds like a stupid question but is it expensive to replace or fix?

If it wiped a spider gear, you are looking at about 200-300 in labor, a new Trac Loc unit, and you may as well buy gears and install them if you can, since it's the same amount of labor.
