Just from that explanation and no vid it sounds like your gear mesh is off. Did you check the pinion gear and are the diffs filled with oil?

Like Smili says. First slide out and remove motor module. Check pinion to spur mesh. If all fine, roll tires. With the drive shaft out, there should be no resistance and diffs should turn freely. Has to be one or another. Check Bearings on spur and ensure slipper is functioning and adjusted properly while you have it apart.Easy to pin down problem.
