Sometimes wheels can be difficult to remove from the vehicle due to foreign material or a tight fit between the wheel center hole and the hub or rotor. These wheels can be removed without damage by using the following procedure:
Caution: Do not allow the penetrating oil to get on the vertical surfaces between the wheel and the drum (or rotor) because penetrating oil in this area could cause the wheel to work loose as the vehicle is driven, resulting in loss of control.
Notice: NEVER use heat to loosen a tight wheel. It can shorten the life of the wheel, wheel nuts and wheel bearings. 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 one's hand or a rubber mallet, is normally acceptable.
Important: Penetrating oil has not been found to be effective in removing tight wheels. If penetrating oil is used, apply the oil sparingly to the wheel's center hole area only.
