WHEEL BEARING AND HUB
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 wheel bearing and hub.
1. Remove the wheel and tire assembly, disc brake caliper and brake rotor. See: Brakes and Traction Control/Disc Brake System/Brake
Rotor/Disc/Service and Repair/Removal and Replacement/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 bearing replacement. Moderate grease weeping from the bearing is
considered normal and should not require replacement of the wheel bearing.
To diagnose a bent hub, measure hub runout. See: Brakes and Traction Control/Disc Brake System/Brake Rotor/Disc/Testing and Inspection
