1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
2. Mark the relationship of the wheel to the hub.

4. Install and fully seat the wheel nuts in order to securely retain the rotor to the hub and bearing.
5. Secure the J 8001 to the knuckle. Ensure that the J 8001 button contacts the rotor surface about 13 mm (0.500 in) from the outer edge of the brake rotor.
6. Set the J 8001 to zero.
7. Use your hands in order to push and pull the rotor edge near the J 8001 . Observe the dial on the J 8001 .

1. Mark the relationship of the rotor to the hub.

Notice: Whenever the brake rotor has been separated from the wheel bearing flange, clean any rust or foreign material from the mating surface of the rotor and flange with the J 42450 hub cleaning kit. Failure to do this may result in increased lateral runout of the rotor and brake pulsation.

2. Remove the brake rotor. Refer to Brake Rotor Replacement in Disc Brakes.
3. Clean any rust or foreign material from the mating surface of the rotor and the hub.
4. Ensure that the J 8001 button contacts the vertical surface of the hub as close as possible to the outer edge.
5. Set the J 8001 to zero.
6. Rotate the hub one complete revolution. Inspect the runout indicated on the dial.

Does the runout indicated on the dial exceed the value shown?

0.05 mm (0.002 in)
