Wheels can sometimes be difficult to remove due to corrosion or a tight fit between the wheel center pilot hole and the hub or rotor.

Wheels can be removed without damage as follows:

  1. Tighten all wheel nuts on the wheel and then loosen each nut only two turns.
  2. Lower the vehicle onto the floor.
  3. Rock the vehicle from side-to-side as hard as possible to loosen the wheel, or rock it from drive to reverse allowing the vehicle to move several feet in each direction. Apply quick, hard jabs on the brake pedal to loosen the wheel.
  4. Stop the engine and raise the vehicle.
  5. Remove the wheel nuts and wheel. Do not let aluminum wheels stand vertical at any time. Lay the black unfinished surface of the wheel on a soft clean surface. Penetrating oil is not effective in removing tight wheels.
  6. 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 loss of control and an injury accident.

  7. Excessive force such as hammering the wheel or tire can also cause damage and is not recommended. Slight tapping of the tire side wall, such as with your hand or rubber mallet, is normally acceptable.
