A wheel end assembly for a vehicle includes an axle tube and a housing
secured to the end of the axle tube. A hub includes a drive flange
located axially outward from the housing and a spindle projecting from
the drive flange into the housing. The hub spindle has a substantially
solid body with drive splines about an external surface of the spindle.
Rolling elements are located between the hub spindle and the housing for
enabling the hub to rotate about an axis. The hub includes an inner race
defining an inner raceway located around and carried by the hub spindle
for engagement with the rolling elements. An axle shaft is positioned
within the axle tube and includes splines that are coupled to the
external drive splines of the hub. The axle shaft includes a
substantially hollow end positioned within the housing having the shaft
splines positioned within an inner surface of the hollow end of the axle
shaft. The hollow end is configured for receiving a portion of the hub
for coupling the shaft splines with the drive splines of the hub for
transferring torque from the axle shaft to the hub.
