I have a tc3 car that I race at my local track. I have been experiencing difficultly with the differentials. They either loosen up on me. On the Screw breaks inside the diff. I really would appreciate any advice you can give me.

Thanks Rick

try the onroad forums.. there is a tc3 help thread...

sounds like the small balls and the washers ( ie thrust bearings setup), on the diff screw are not properly installed... check your manual for pics on how to do it..

Thanks. I will check that out.
