I've since disassembled the center and rear diff and found the gears to be in good shape. Am I missing something here?

Rear diff gets a good majority of the force under accerleation..

CHeck your teeth on the rear diff ring gear

they are probably rounded slightly causing the gears to skip under load.


ANother possibility is that one of the magnets inside your motor is debonded and is grinding on the inner windings of the motor- had that happen this past weekend
