Abstract: The present invention relates to a unitary hub assembly for use in mounting a driven wheel on a steering knuckle of a vehicle. The unitary hub assembly has a hub adapted to be connected with a drive shaft and the driven wheel. A bearing assembly is connected to the hub to support the hub for rotation relative to the steering knuckle. The hub assembly also has a flange which is connected to the bearing assembly and the steering knuckle. The flange secures the hub assembly to the steering knuckle. When the hub is connected with the driven wheel and the steering knuckle, it supports the wheel for rotation relative to the steering knuckle and transmits drive and steering forces to the wheel.

Abstract: An apparatus is provided to rotatably support a shaft having an annular worn portion and unworn portions disposed adjacent to axially opposite ends of the worn portion. The apparatus includes a plurality of bearing elements. The bearing elements engage the unworn portion of the shaft at a location adjacent to the worn portion of the shaft. A sleeve encloses the bearing elements and the worn portion of the shaft. Opposite ends of the sleeve are closed by seals which engage unworn portions of the shaft.
