Front Hub And Bearing

DIAGNOSIS AND TESTING - HUB AND BEARING

NOTE: The wheel bearing is designed to last for the life of the vehicle and requires no type of periodic maintenance.

The following procedure may be used for diagnosing the condition of the hub and bearing.

1. Remove the wheel and tire assembly, disc brake caliper and brake rotor. Brake Rotor - Removal
2. Rotate the wheel hub checking for resistance or roughness.

Any roughness or resistance to rotation may indicate dirt intrusion or a failed hub bearing. If the bearing exhibits any of these conditions, the hub bearing will require replacement. Do not attempt to disassemble the bearing for repair. If the wheel bearing is disassembled for any reason, it must be replaced.

Damaged bearing seals and the resulting excessive grease loss may also require hub and bearing replacement. Moderate grease weeping from the bearing is considered normal and should not require replacement of the hub and bearing.

To diagnose a bent hub, measure hub runout. Testing and Inspection
