Abstract
A differential (10) having differential gears (56,58) connecting a pair of axles (44,46) includes a pair of opposed cam rings (66,68) mounted for rotation with one of the axles. One cam ring (66) is adapted to lock the axles (44,46) relative to the differential housing (12) when no differential rotation exists between the axles (44,46) and is movable when differential rotation does exist by the interaction between the cam rings (66,68) to an inoperative position to unlock the axles from the housing. A lockout ring (70) maintains the cam rings (66,68) in disengaged relation during differential rotation.
