Installation Procedure
2008 Chevrolet Chevy Express G2500, Van Cargo, 6.6 6SECTION Installation Procedure
- Use the J 42450-A to clean all rust and contaminants from the mating surface of the hub flange. See Special Tools .
- Use the J 41013 to clean all rust and contaminants from the inside diameter of the hat section of the brake rotor to prevent any foreign material from getting between the brake rotor and the hub flange. See Special Tools .
- Inspect the mating surfaces of the hub/axle flange and the rotor to ensure that there are no foreign particles or debris remaining.
IMPORTANT:
Whenever the brake rotor has been separated from the hub/axle flange, any rust or contaminants should be cleaned from the hub/axle flange and the brake rotor mating surfaces. Failure to do this may result in excessive assembled lateral runout (LRO) of the brake rotor, which could lead to brake pulsation.
IMPORTANT:
If the rotor was removed using the jack screw method you must ensure that the hub flange is free of nicks or marks caused by this procedure. Remove all raised nicks or marks before installing the rotor.
