HUB & BEARING (REAR)
CAUTION:If a vehicle is equipped with anti-lock brakes, the tone wheel for the rear wheel speed sensor is pressed onto the hub and bearing. Make sure any replacement bearing has the tone wheel on it before installation.
The rear wheel bearing and rear wheel hub of this vehicle are a one-piece sealed unit, or hub and bearing unit type assembly. The hub and bearing is mounted to the center of the rear axle using 4 mounting bolts. It has 5 wheel mounting studs on the hub flange. All wheel drive vehicles have a hub and bearing unit with a splined hole in the center of the hub for rear driveshaft acceptance.
The hub and bearing has internal bearings that allow the hub to rotate with the tire and wheel assembly (and driveshaft on all wheel drive vehicles). The 5 wheel mounting studs mount the tire and wheel assembly, and disc brake rotor to the vehicle. On all wheel drive vehicles, the splined mating of the driveshaft and hub allows the driveshaft to rotate with the hub and wheel. Front wheel drive vehicles equipped with anti-lock brakes have a tone wheel mounted to the rear of the hub and bearing that is used in conjunction with the wheel speed sensor to measure wheel speed.
