GM Service Manual Online
For 1990-2009 cars only

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.
