A wheel end assembly includes an output shaft that is directly mountable
to a wheel adapter to drive a vehicle wheel. A gear assembly is coupled
to the output shaft to transfer driving force from an input to the output
shaft. The gear assembly includes an output gear that is directly coupled
to the output shaft. Thus, the wheel adapter and output gear are both
supported directly on the output shaft. The gear assembly and output
shaft are substantially enclosed within a housing that is mounted to a
non-rotating vehicle component. The output shaft is solely supported by a
pair of bearings for rotation relative to the housing. The bearings are
installed for direct engagement with the output shaft and housing.
