Hub / Bearing

OPERATION

The hub and bearing has internal bearings that allow the hub to rotate with the tire and wheel assembly. The five wheel mounting studs mount the tire and wheel assembly, and disc brake rotor or brake drum to the vehicle.


Vehicles equipped with antilock brakes have a wheel speed sensor and tone wheel mounted to the rear of the hub and bearing. The tone wheel rotates with the hub which is sensed by the wheel speed sensor.
