An improved vehicle wheel hub mounting system includes a wheel hub, an axle spindle, a bearing assembly, and a threaded fastener. The wheel hub defines an axis and including a generally axially extending body having bore formed therethrough. The bore of the wheel hub includes an internal splined portion and an inner annular wheel hub surface spaced apart from the internal splined portion. The inner annular wheel hub surface defines a predetermined wheel hub inner diameter. The axle spindle is connected to the wheel hub for rotation therewith and includes a generally axially extending body having an external splined portion and an outer annular axle spindle surface spaced apart from the external splined portion. The external splined portion of the axle spindle matingly receives the internal splined portion of the wheel hub to connect the axle spindle to the wheel hub for rotation therewith. The outer annular axle spindle surface of the axle spindle defines a predetermined axle spindle outer diameter which receives the inner annular wheel hub surface of the wheel hub so as to support the wheel hub thereon. The bearing assembly is pressed onto at least a portion of one of the wheel hub and the axle spindle and is adapted to be secured to a non-rotatable component of the vehicle so as to rotatably support the wheel hub and the axle spindle relative thereto. The threaded fastener nut is secured to the axle spindle for preloading the bearing assembly and securing the wheel hub and the axle spindle together for rotation with one another. |
