ABSTRACT:
A shaft retention and spacer mechanism, referred to as a button lock assembly, is installed between the ends of the axle shafts within the differential housing of a differential assembly. The end of each axle shaft includes a button-like end pad formed by an annular groove that is adapted to receive a C-clip therein for axially locating and restraining a side gear between the differential housing and the axle shaft. The button lock assembly includes a spacer block having a peripheral flange extending outwardly from its opposite lateral face surfaces so as to define a pair of open-ended retention chambers. The spacer block is disposed between the axle shafts such that the button-like end pads are positioned within the retention chambers. The button lock assembly further includes a lock cap that is secured to the spacer block for enclosing the open end of the retention chambers to surround the end pads. Upon installation of the C-clip into the grooves, the end pads are retained in the retention chambers of the spacer block and the C-clips are laterally bounded by the side gear and the button lock assembly.
