ABSTRACT:
One embodiment of the present invention is a differential assembly which includes a two part pinion pin that allows the pinion pin to be removed for parts service and/or replacement without removing the differential case and ring gear from the differential housing. In differentials in which the ring gear interferes with the removal of the pinion pin, the two part pinion pin allows removal of the pinion pin in two pieces, each being rotated about its axis for insertion or removal to provide the best position for clearance with the ring gear. The two part pinion pin may be advantageously used with differentials of various kinds.
