An axle system for a vehicle having an input shaft and an input helical gear. Circumferentially extending from at least a portion of an outer surface of an intermediate portion of the input shaft is an increased diameter portion. A bearing journal surface is disposed directly adjacent to a first end portion of the increase diameter portion and a tapered roller bearing journal surface is disposed directly adjacent to a second end portion of the increased diameter portion of the input shaft. Disposed outboard from the bearing journal surface is a bearing and a tapered roller bearing is disposed outboard from the tapered roller bearing journal surface of the input shaft. At least a portion of the tapered roller bearing is disposed with a tapered roller bearing receiving portion circumferentially extending along at least a portion of an inner surface of an input helical side gear.
