all of the sudden my OT Carbons has a mechanical issue. if i let off the throttle it was stopping instantly even after changing throttle settings. Doing some testing i moved the motor away to rule out the motor so the pinion gear can spin freely. I can spin each individual wheel; even the front and rears. If i put the car down and try to physically roll it is it install locked up. I also notice that the drive shaft cup is touching the motor heat sink. Any idea what the issue is? it’s obviously an issue with the diffs?
