A wheel hub assembly that has a hub retained within a rotatable inner race of a bearing. The bearing is non-rotatably mounted by a portion of it's outer race within the bore of a bearing housing. This bearing housing has threaded holes on a diameter within its' face to accept bolts by attachment to an axle housing end support. Non-rotatably mounted within the bearing housing is a lip seal to prevent contaminants from entering the bearing. On the face of the hub is a groove on a diameter for accepting an o-ring sealing member to furnish a barrier between the face of the hub and the drive axle preventing loss of differential lubrication. Bolts are threaded through the hub on a diameter within its face for securing a wheel and engaging a drive axle, whereby the support of the wheel is not dependent upon the drive axle.
