Removal Procedure


    Object Number: 1255657  Size: SH
  1. Remove the wheel cover.
  2. Loosen the wheel nuts.
  3. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  4. Remove the wheel nuts.
  5. 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.

  6. Remove the wheel and tire assembly.
  7.    Important: Difficulty in removing the wheels from the vehicle can be due to foreign material or to a tight fit between the wheel centerhole and the hub or the rotor. These wheels can be removed by:

    • Retightening the wheel nuts on the affected wheel and then loosening the wheel nuts by 2 turns.
    • Lowering the vehicle and rocking it from side to side as hard as possible, using 1 or more person's body weight to loosen the wheel.
    • Raising the vehicle and removing the wheel.

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.

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

Installation Procedure


    Object Number: 1255657  Size: SH

    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.

  1. Mount the wheel and tire assembly.
  2. Install the wheel nuts in the sequence shown. Do not tighten the wheel nuts.
  3. Notice: Refer to Fastener Notice in the Preface section.

  4. Lower the vehicle.
  5. Tighten
    Tighten the wheel nuts to 110 N·m (81 lb ft).

  6. Install the wheel cover.
