Abstract
A limited slip differential assembly comprising a differential case and two side gears rotatably supported within the differential case. Each of the side gears provided with a pre-loaded clutch pack mounted on a hub portion of the side gear. In one embodiment, a lock ring is permanently pressed on the hub portion of the side gear adjacent a collar and the clutch pack for retaining the clutch pack in a predetermined pre-loaded condition. In a second embodiment, an adjustment collar is threaded onto the side gear and a thrust washer having a selected thickness maintains the pre-load condition. In both embodiment, a side gear/clutch pack assembly may be pre-assembled as a pre-loaded self-contained module before the various components of the differential assembly are assembled in the differential case.
