Abstract
A method for controlling an axle shaft endplay in a vehicle is disclosed. The desired axle shaft endplay is determined by a manufacturer based on the specific operating conditions of a differential assembly. In accordance with the endplay controlling method of the present invention, first the differential is partially assembled by mounting side gears and a set of differential pinion mate gears in a differential case. Then, the manufacturer determines a thickness of a shim ring disposed between an axle shaft retainer ring and the differential side gear, which would provide the desired endplay. The appropriate shim ring is selected from an endplay controlling kit comprising a plurality of the shim rings of assorted thickness. Next, axle shafts are inserted into the differential case through the side gears, and the selected shim ring is mounted to the axle shaft. Finally, the retainer ring is secured to the axle shaft.
