Dodge Journey: Hub and bearing

DESCRIPTION

Front Suspension
Fig. 31: Front Hub And Bearing Mounting

The front wheel bearing and wheel hub of this vehicle are a one piece sealed unit or hub and bearing unit type assembly.

The hub and bearing (1) is mounted to the knuckle using four mounting bolts (2) and to the axle half shaft using a retaining nut. The center of the hub and bearing is splined to match the outer joint of the axle half shaft.

Each front hub and bearing has five wheel mounting studs on the hub flange for mounting the wheel to the vehicle. The wheel mounting studs are the only replaceable components of the hub and bearing. Otherwise, the hub and bearing is serviced as a complete assembly.

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.

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.

REMOVAL

NOTE: Before proceeding, review all Warnings and Cautions.

1. Raise and support the vehicle.
