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.


Caution: 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.


Notice: 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



Important:
* 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.
