Rear

HUB / BEARING DESCRIPTION
The rear wheel bearing and wheel mounting hub used on this vehicle are a one-piece sealed unit or hub and bearing assembly. It is permanently lubricated when assembled and is sealed for life. There is no periodic lubrication or maintenance recommended for these units.







The hub and bearing is mounted on the spindle which is bolted to the axle. The hub and bearing is secured to the spindle using a special nut.

Vehicles equipped with antilock brakes have rear hub and bearings with the tone wheel for the rear wheel speed sensors pressed onto the hub.

The only serviceable components of the hub and bearing are the wheel mounting studs pressed into the hub.

OPERATION
The hub and bearing adapts the tire and wheel assembly to the axle mounted spindle. It's bearing allows the tire and wheel assembly to rotate freely on the vehicle. The brake drum or brake rotor mounts to the hub's wheel mounting studs aiding in stopping the vehicle when required.

On vehicles equipped with antilock brakes, the tone wheel pressed onto the hub allows the brake system to sense wheel motion.
