Abstract
A differential includes a differential case; a side gear comprising a helical face gear; a helical pinion configured for meshing engagement with the side gear; and a pinion housing configured to support the helical pinion. The pinion housing includes a first face; a second face opposing the first face; a first projection located on the first face; and a second projection located on the second face. In some embodiments, the differential further comprises an actuator configured for engagement with the pinion housing and a plurality of friction plates disposed between the actuator and the differential case. The pinion housing also includes an aperture or hole extending radially inwardly from an outer radial surface of the generally annular ring; and a channel extending from the first face to the second face, wherein the channel is substantially radially aligned with the aperture or hole.
