Abstract: A hydraulic control unit that delivers hydraulic fluid to a limited slip differential includes a hydraulic control unit housing, a vent hole and first and second passageways. The hydraulic control unit housing has an accumulator housing portion that houses a biasing assembly and a piston. The accumulator housing portion forms an accumulator chamber with the piston. The vent hole is defined in the hydraulic control unit housing. The first passageway is defined in the hydraulic control unit housing. The second passageway is defined in the hydraulic control unit housing that intersects the vent hole and is oriented at a different angle than the first passageway. The vent hole is dual purpose permitting hydraulic fluid entry into the accumulator chamber through the second passageway while air is permitted to escape the hydraulic control unit housing through the vent hole.

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.
