ABSTRACT:
A differential assembly includes a differential housing including a substantially spherically shaped chamber. A pair of spherically shaped side gears are rotatably positioned in the chamber in driving communication with a pair of spherically shaped pinion gears. A pair of springs are positioned in engagement with the end faces of the side gears to minimize gear lash between the side gears and the pinion gears.
