ABSTRACT:
A differential assembly includes a differential housing defining a chamber and a pair of aligned openings communicating with the chamber. A pair of output shafts extend through the openings in the differential housing and include end segments located within the chamber. A pair of side gears are positioned within the chamber and fixed to the end segments of the output shaft. Paired sets of pinions are rotatably mounted within the differential housing and placed in meshed engagement with each other and with one of the side gears. A retention assembly interconnects the end segments and includes a spacer having a web positioned between and walls partially encompassing the end segments. The retention assembly includes a ring surrounding the spacer to selectively retain and allow removal of clips engaged with the end segments.
