Abstract
A differential axle assembly includes an axle housing having a pair of opposed openings. A differential gear set includes a pair of side gears. Each of the side gears are supported within one of the opposed openings. A plurality of pinion gears engage the side gears. A hypoid ring gear is rotatably supported within the axle housing and a pinion shaft is supported by the hypoid ring gear. The pinion shaft supports the pinion gears in engagement with the side gears. The hypoid ring gear includes a cylindrical inner diameter having a pair of axially spaced inwardly facing annular surfaces and the axle housing includes a pair of axially spaced outwardly facing annular surfaces. The hypoid ring gear is rotatably supported within the axle housing by a pair of roller bearings positioned between the annular surfaces.
