Ford Mustang (1999-2004) Service Manual: Component Tests

Ball Joint Inspection

1. Raise and support the vehicle.

2. Prior to performing any inspection of the ball joints, inspect the wheel bearings.

3. Position a safety stand beneath the front suspension lower arm (3079) to be tested.

4. While an assistant pulls and pushes the bottom of the tire, observe the relative movement between the lower spindle arm and the front suspension lower arm ball joint. Any movement at or exceeding the specification indicates a worn or damaged lower ball joint. Install a new front suspension lower arm.

Wheel Bearing Inspection

1. Raise the vehicle until the tire is off the floor.

2. NOTE: Make sure the wheel rotates freely and the brake pads are retracted sufficiently to allow movement of the tire and wheel assembly.

Grasp each tire at the top and bottom and move the wheel inward and outward while lifting the weight of the tire off the wheel bearing.

3. If the tire and wheel (hub) is loose on the wheel spindle or does not rotate freely, install a new front wheel hub (1104) as necessary.
