Wheels: Service and Repair

CAUTION: Models equipped with chrome plated wheels are not supplied with chrome plated lug nuts. Under no circumstances are chrome plated lug nuts to be used, use only the factory specified lug nuts.

WHEEL INSTALLATION





The wheel studs and nuts are designed for specific applications. Do not use replacement parts of lesser quality or a substitute design. The lug nuts used are a two piece flat face nut.

All aluminum and some steel wheels have wheel stud nuts which feature an enlarged nose. This enlarged nose is necessary to ensure proper retention of the aluminum wheels.

Before installing the wheel, be sure to remove any build up of corrosion on the wheel mounting surfaces. Ensure wheels are installed with good metal-to-metal contact. Improper installation could cause loosening of wheel nuts. This could affect the safety and handling of your vehicle.





To install the wheel, first position it properly on the mounting surface. All wheel nuts should then be tightened just snug. Gradually tighten them in sequence to specified torque. Never use oil or grease on studs.

DUAL REAR WHEEL INSTALLATION
Dual rear wheels use a special heavy duty lug nut wrench. It is recommended to remove and install dual rear wheels only when the proper wrench is available. The wrench is also use to remove wheel center caps for more information refer to Owner's Manual.

The tires on both wheels must be completely raised off the ground when tightening the lug nuts. This will ensure correct wheel centering and maximum wheel clamping.

A two piece flat face lug nut with right-hand threads is used for retaining the wheels on the hubs.

The dual rear wheel lug nuts should be tightened according to the following procedure:
- Place two drops of oil to the interface of the nut/washer before installing on the wheel stud.





NOTE: Do not use more then two drops of oil on the nut/washer, since the center caps attach in this area.

- Tighten the wheel lug nuts in the numbered sequential pattern until they are snug tight. Then tighten lug nut to specified torque following same number sequence.
- Tighten lug nuts in same numbered sequence a second time to the specified torque. This will ensure that the wheels are thoroughly mated.
- Check lug nut specified torque after 100 miles (160 kilometers). Also after 500 miles (800 kilometers) of vehicle operation.

NOTE: Wheel lug nuts should be tightened to specified torque at every maintenance interval thereafter.
