Firebird V8-5.7L VIN G (2001)
Wheels: Testing and Inspection
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
-
Damage to the vehicle caused by the modified ground clearance
-
Speedometer and odometer inaccuracy
