Abstract
A differential includes a differential case; a side gear; a pinion configured for meshing engagement with the side gear; and a pinion housing configured to support the 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. 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. In embodiments, the pinion housing includes one or more transfer formations configured to transfer torque from the differential case, and the pinion housing is configured to permit movement in an axial direction between a pair of side gears.
