- Use a straight edge 203-229 mm
(8-9 in) long. Place the straight edge on the wheel inboard
mounting surface. Try to rock the straight edge up and down within the mounting
surface.
- Repeat this procedure
on at least 3 or 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 is raised above the outer ring if the wheel
mounting surface is bent on a tire changer. |
| • | If the straight edge can be rocked, the mounting surface is bent
and the wheel should be replaced. |
- 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 |
Important:
| • | Replacement wheels must be equivalent to the original equipment
wheels in the following ways: |
| • | A wheel of incorrect size or type may affect the following conditions: |
| - | Wheel and hub-bearing life |
| - | Speedometer/odometer calibration |
| - | Vehicle ground clearance |
| - | Tire clearance to the body and the chassis |
- Replace the wheel if the wheel is bent. Replace the wheel if the wheel/nut
boss area is cracked.
