Wheel Hub: Description and Operation

DESCRIPTION





The front wheel bearing and wheel hub of this vehicle are a one piece sealed unit or hub and bearing unit type assembly.

The hub and bearing (1) is mounted to the knuckle using four mounting bolts (2) and to the axle half shaft using a retaining nut. The center of the hub and bearing is splined to match the outer joint of the axle half shaft.

Each front hub and bearing has five wheel mounting studs on the hub flange for mounting the wheel to the vehicle. The wheel mounting studs are the only replaceable components of the hub and bearing. Otherwise, the hub and bearing is serviced as a complete assembly.
