Service Notes

^ Wheels must be replaced when they are bent, dented, have air leaks that cannot be repaired, elongated bolt holes, or have excessive lateral or radial runout. Wheels with lateral or radial runout greater than the recommended specification may cause a high-speed vehicle vibration.
^ Replacement wheels must be equal to the original equipment wheels in load capacity, diameter, width, offset and mounting configuration. An improper wheel may affect wheel, tire and wheel bearing life, ground and tire clearance, or speedometer calibrations.
^ Corrosion buildup can result in the wheels sticking to the front disc brake rotor or the brake drum (rear disc brake rotor, if equipped) after extensive service. To prevent this from recurring once the wheels are removed, use the following procedure:
1. Clean the contact area of the front disc brake rotor or the brake drum (rear disc brake rotor, if equipped) and wheel with a wire brush, steel wool, or suitable material.
2. Coat the contact area of the wheel with Silicone Dielectric Compound D7AZ-19331-A or equivalent meeting Ford specification ESE-M1C171-A. Do not apply grease to the lug nut seats or the lug bolts.
3. Install the wheel on the vehicle.
