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 rusted

    • The wheel leaks air

Warning: If you are replacing the wheel(s), the wheel stud(s), the wheel nut(s) or the wheel bolt(s), install only new Saturn original equipment parts. Installation of used parts or non-Saturn 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

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.

Steel wheel identification is stamped into the wheel near the valve stem.
