Removal Procedure


    Object Number: 1242010  Size: SH
  1. Loosen the wheel bolts.
  2. Notice: Refer to Vehicle Lifting and Jacking Notice in the Preface section.

  3. Raise and suitably support the vehicle.
  4. Remove the wheel bolts.
  5. Caution: 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 a loss of control and an injury accident. 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 proper torque to avoid bending the wheel or brake rotor or drum.

    Notice: 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.

    Important: Penetrating oil is not effective in removing tight wheels. If it is used, however, apply it sparingly and only to the wheel centerhole area.

    Caution: 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.

  2. Install the wheel nuts and hand tighten the wheel nuts.
  3. Lower the vehicle.
