Also ensure the slipper is set correctly and not locked up. Holding both wheels down, you should be able to rotate the spur with a thumb, albeit it will be stiff.
Also check the diff is tight enough by holding one wheel down and the spur gear, then try and rotate the other wheel of the car. You should see the slipper plates spinning. If you don;t and the wheel is spinning then it means your diff is too loose.
Tighten the diff a quarter turn and try again.
