Abstract
An automatic locking differential of the type having C-clip retainers adapted for mounting in peripheral grooves contained in the adjacent ends of the output shafts includes an annular center driver gear, a center cam member arranged concentrically within the center driver gear, and at least one resilient preload member for biasing a pair of side gears into engagement with an internal annular shoulder on the center cam member, thereby to dampen the rotational play between the center cam and the center driver member. A pair of preload resilient members may be provided at the remote ends of the side gears for axially biasing the side gears together toward engagement with the internal diameter on the center cam member.
