Abstract: A plastic gear is rotatably supported on at least one plastic fixed support stud, which is preferably formed of plastic and molded on a metal support plate. The fixed support stud has three equiangularly spaced lobes extending from its outer surface without any nominal clearance with an inner surface of a hub of a plastic gear defining a bore in the gear hub to receive the fixed support stud.

Abstract: An adjustment collar for a positioning a ring gear to a differential case. The ring gear is splined to the differential case so as to allow axial displacement. The adjustment collar is threaded onto the differential case adjacent to the ring gear. The adjustment collar is rotated to axially position the adjustment collar, and consequently the ring gear relative to the differential case and axle assembly. The adjustment collar and ring gear are bolted to one another to prevent relative rotation there between. Because the ring gear is splined to the differential case, relative rotation between the ring gear and differential case, and consequently the adjustment collar and the differential case, is prevented. Because the ring gear and adjustment collar are locked to one another, the two components are thus prevented from both axial and rotational movement.
