GENERAL INFORMATION
Penetrating oil has not been found to be effective in removing tight wheels. However, if it is used, it should be applied sparingly to the hub surface 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. Never use heat to loosen a tight wheel. It can shorten the life of the wheel, studs or hub and bearing. Wheel nuts must be tightened in sequence and to the proper torque to avoid bending the wheel or rotor.

Excessive force such as hammering the wheel or tire can also cause damage. Use a rubber mallet to lightly tap the tire's sidewall.

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 as follows:
1. Tighten all wheel nuts on the affected wheel, then loosen each wheel nut two turns.
2. Lower vehicle onto floor.
3. Rock the vehicle from side to side as hard as possible using one or more person's body weight to loosen the wheel, and/or rock the vehicle from "Drive" to "Reverse" allowing it to move several feet in each direction. Apply quick, hard jabs on the brake pedal to loosen the wheel.

REMOVE OR DISCONNECT
1. Raise vehicle and suitably support.
2. Hub cap.
3. Wheel nuts.
4. Mark location of tire and wheel to hub.
5. Tire and wheel.

CAUTION: Before installing a wheel, remove any build-up of corrosion on the wheel mounting surface or rotor, by scraping and wire brushing. Installing wheels without good metal-to-metal contact at mounting surfaces can cause wheel nuts to loosens which may later allow the wheel to come off while the vehicle is in motion.

^ Clean wheel nuts, studs and the wheel and rotor mounting surfaces.

INSTALL OR CONNECT

NOTICE: Always use the correct fastener in the proper location. When you replace a fastener, use ONLY the exact part number for that application. The manufacturer will call out those fasteners that require a replacement after removal. The manufacturer will also call out the fasteners that require thread lockers or thread sealant. UNLESS OTHERWISE SPECIFIED, do not use supplemental coatings (paints, greases, or other corrosion inhibitors) on threaded fasteners or fastener joint interfaces. Generally, such coatings adversely affect the fastener torque and the joint clamping force, and may damage the fastener. When you install fasteners, use the correct tightening sequence and specifications. Following these instructions can help you avoid damage to parts and systems.

1. Tire and wheel.
2. Align locating mark of tire and wheel to hub.

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 torque shown in "Specifications". 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.

3. Wheel nuts.
^ Tighten wheel nuts in sequence to 140 Nm (l00 ft. lbs.).
4. Hub cap.
5. Lower vehicle.
