Slipping Diff
 

today, after doing alot of doughnuts in my Xmod i put my normal tires back on and tried running the car normal, and after turning way to sharp and flipping the car, i tried to go forward and the car wouldnt, the motor turned and the diff spun, but the axels didnt, and i would hear weird noises comming from the diff, i pushed the wheels in and the diff gripped again. what happened? did i damage the diff, and how can i fix this.

fixed
 

i gutted the white diff and put a metal and 3 paper washers from a computer motherboard. tightened it down and now it works great.

Id made a Posi-track rear axle.. kept having problems and had a spare so took teh ****ty one apart, took out bearings and super glued it all together.. its nice i guess
