Patent abstract

An axle assembly that includes a differential casing, which is rotatable about an axis, a pair of side gears that are disposed within the differential casing, a spacer and a cross pin. The spacer is disposed between the side gears. The cross pin is fixed to the differential casing and extends through the spacer. The cross pin is employed to limit end play of the axle shafts in a direction toward one another. The aperture in the spacer that receives the cross pin is relatively larger than the cross pin so that the spacer can control end play of the side gears independently of the cross pin.
