Wheels: Description and Operation

Replacement Wheels Description

Replace the wheel if any of the following conditions exist:

* The wheel exhibits excessive runout.
* The wheel is bent.
* The wheel mounting surface is bent.
* The wheel is cracked.

Replace the wheel, the wheel hub studs and the wheel nuts, if any of the following conditions exist:

* The wheel has elongated wheel stud holes.
* The wheel nuts loosen repeatedly.

Warning

If you are replacing the wheel(s), the wheel stud(s), the wheel nut(s) or the wheel bolt(s), install only new GM original equipment parts. Installation of used parts or non-GM original equipment parts may cause the wheel to loosen, loss of tire air pressure, poor vehicle handling and loss of vehicle control resulting in personal injury.

Caution: The use of non-GM original equipment wheels may cause:

* Damage to the wheel bearing, the wheel fasteners and the wheel
* Tire damage caused by the modified clearance to the adjacent vehicle components
* Adverse vehicle steering stability caused by the modified scrub radius
* Damage to the vehicle caused by the modified ground clearance
* Speedometer and odometer inaccuracy

Note:
* Replacement wheels must be equivalent to the original equipment wheels in the following ways:

- The load capacity.
- The wheel diameter.
- The rim width.
- The wheel offset.
- The mounting configuration.

* A wheel of the incorrect size or type may affect the following conditions:

- Wheel and hub-bearing life.
- Brake cooling.
- Speedometer/odometer calibration.
- Vehicle ground clearance.
- Tire clearance to the body and the chassis.

Aluminium wheel identification is cast into the inboard side of the wheel.
