Replacement Wheels Description

Replace the wheel if any of the following conditions exist:

^ The wheel exhibits excessive runout.
^ The wheel is bent.
^ The wheel is cracked.
^ The wheel is severely corroded.

Important: Air leaks caused by porosity on aluminum wheels are repairable.

^ The wheel leaks air.

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

Replace the wheel, the wheel studs and the wheel/nuts, or the wheel bolts if applicable, if any of the following conditions exist:

^ The wheel has elongated bolt holes.
^ The wheel/nuts, or bolts if applicable, loosen repeatedly.

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