For 1990-2009 cars only

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.

Penetrating oil has not been found to be effective in removing tight wheels. However, if you use penetrating oil, apply the oil sparingly to the wheel center hole area only.

Sometimes wheels may be difficult to remove due to foreign material or a tight fit between the wheel center hole and the rotor. Excessive force such as hammering the wheel or the tire may cause damage and is not recommended. Slight tapping on the tire sidewall using a large rubber mallet is acceptable.

The wheel may be removed without damage using the following procedure:

  1. Tighten all wheel nuts on the affected wheel. Then loosen each nut two turns. Rock the vehicle from side to side. If this is not effective, proceed to step 2.
  2. Rock the vehicle 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. If the wheel still does not free up, then rock the vehicle again from side to side as hard as possible using one or more persons' body weight. If the wheel is still tight, repeat the procedure.
  3. Raise the vehicle. Support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  4. Remove the wheel cover, if equipped.
  5. Remove the wheel nuts. Mark the location of the tire and wheel assembly to hub assembly.
  6. Caution: Before installing a wheel, remove any buildup of corrosion on the wheel mounting surface and brake drum or rotor by scraping and wire brushing. Installing wheels without good metal-to-metal contact at the mounting surfaces can cause wheel nuts to loosen, which may later allow the wheel to come off while the vehicle is in motion.

  7. Clean the wheel nuts, studs and the wheel and brake drum or rotor mounting surfaces.

Installation Procedure

  1. Install the hub cap on the aluminum wheel, if removed.
  2. Install the tire and wheel assembly. Align the locating mark of the tire and wheel to the hub assembly.

  3. Object Number: 70082  Size: SH

    Caution: Never use oil or grease on studs or nuts. Tighten the wheel nuts with your fingers until they are snug. Then, tighten the nuts (in the sequence shown) to the fastener tightening specification shown in Specifications in this Section. Improperly tightened wheel nuts could eventually allow the wheel to come off while the vehicle is moving, possibly causing loss of control, personal injury, and property damage.

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  4. Install the wheel nuts.
  5. Tighten
    Tighten the wheel nuts in sequence to 140 N·m (100 lb ft).

  6. Install the wheel cover, if equipped.
  7. Lower the vehicle.
