    6. WARNING:

    If penetrating oil gets on the vertical surfaces between the wheel and the rotor or drum it could cause the wheel to work loose as the vehicle is driven, resulting in loss of control and an injury accident.

    CAUTION:

    Never use heat to loosen a tight wheel. It can shorten the life of the wheel, studs, or hub and bearing assemblies. Wheel nuts must be tightened in sequence and to the specified torque to avoid bending the wheel or rotor.

    CAUTION:

    Improperly tightened wheel bolts or nuts can lead to brake pulsation and rotor damage. In order to avoid expensive brake repairs, evenly tighten the wheel bolts or nuts to the proper torque specification.

    1. Loosen each nut 2 complete turns.

    WARNING:

    Before installing the wheels, remove any buildup of corrosion on the wheel mounting surface and brake drum or disc mounting surface by scraping and wire brushing. Installing wheels with poor metal-to-metal contact at the mounting surfaces can cause wheel nuts to loosen. This can cause a wheel to come off when the vehicle is moving, causing loss of control and possibly personal injury.

    NOTE:
    • Wear approved safety glasses when performing the following service procedures.
    • DO NOT use power grinders to clean any of the brake rotor or brake drum to wheel contact areas.
  9. Using a wire brush or wire wheel, clean the rotor to wheel or brake drum to wheel contact area.
  10. Where possible, use the CH-41013  kit to clean the contact areas of the wheel to brake rotor or brake drum.
  11. Using the CH-42450  kit (1), clean the surface around the wheel studs.
  12. Clean the threads of the wheel studs. If the threads are damaged, replace the wheel stud.
  13. After cleaning all the contact areas, use brake clean or denatured alcohol to remove all the dirt and debris from wheel nuts, brake rotor or drum.
  14. Inspect and clean the contact area of the wheel. Refer to Wheel Mounting Surface Check .
