Abstract
Abstract An automotive differential has a differential case rotatably mounted in a differential carrier by a pair of spaced bearing means which are infinitely adjustable to accurately center the differential case in the differential carrier. Each of the bearing means are adjustable by virtue of a shim having ramps on one face which engage cooperating ramps on the outer race of a tapered roller bearing having a thrust capacity in one direction. Adjustment is effected by relative rotation between the shim and the outer race and is maintained by an arcuate strip deformed into interlocking engagement with serrations on the shim and the bearing outer race.
