OK here goes i got my truck up and going but now i have a diff problem. it worked for about ten mins and then i puched it and well engine rev'd up and no movement so i tookt he diff out and held both sides and tried to roll the diff gear on my leg and it just slid down my leg gears looked good. but didnt take all the grease out to check the other diff cup gear. will tomorrow. but if that is good what could it be?? any suggestions will be helpful.

thanks

TJ
