Abstract
A vehicle axle assembly including an axle housing, carrier assembly, and first and second axle shafts. The axle housing is formed from an upper beam and a lower beam that are positioned in a clam-shell arrangement. The carrier assembly includes a carrier housing and a differential that includes a ring gear arranged in meshing engagement with a pinion. The first and second axle shafts extend outwardly from the differential in opposite directions. The pinion is rotatably supported by a self-lubricating cartridge pinion input bearing and the outboard ends of the first and second axle shafts are rotatably supported by self-lubricating and unitized grease wheel end bearings. These bearings do not require lubrication from oil contained inside the axle housing allowing for a reduced oil fill level in the axle housing, creating less viscous losses and better efficiency.
