ABSTRACT:
An axle assembly that includes a differential case which is rotatable about an axis, a pair of side gears that are disposed within the differential case, a spacer ring and a cross pin. The spacer ring is disposed between the side gears. The cross pin is fixed to one of the differential case and the spacer ring and extends through the spacer ring. The aperture in the spacer that receives the cross pin may be larger than the cross pin so that the spacer ring can control end play of the side gears independently of the cross pin.
