Wheels: Testing and Inspection
Wheel Mounting Surface Check
Replace any wheels that are bent or dented, or have excessive lateral or radial runout. Wheels with runout greater than specified may cause objectionable
vibrations.
1. Use a straightedge 203 - 229 mm (8 - 9 inch) long. Place the straight edge on the wheel inboard mounting surface. Try to rock the straightedge up
and down within the mounting surface.
2. Repeat this procedure on at least 3-4 different positions on the inboard mounting surface.
^
The outer ring of the mounting surface normally is raised above everything inside the mounting surface.
^
The mounting surface will be raised above the outer ring if the wheel mounting surface has been bent on a tire changer.
^
If you can rock the straight edge, the mounting surface is bent and you must replace the wheel.
3. Inspect the mounting wheel/nut holes for damage caused from over-torquing the wheel/nuts. Inspect for collapsed wheel/nut bosses. Inspect for
cracked wheel bosses.
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
