I did rebuild the diff and it seems to feel good but the real test will be when I actually get it driving.
OK, Check part #3931, motor adjustment clamp. Stormer hobbies, Tower and Amain all have it in stock. Its a common failure, if you look at the exploded view You will see a small spring on one of the mounting bolts. It gets lost and the motor clamp is over tightened and breaks. Easy fix if that is whats broken.
Do you have the composite diffs or steel, Run a few laps to break in the diffs then readjust. GOOD LUCK have fun!!!!!!
