Grand AM L4-144 2.4L DOHC VIN T SFI (1997)
Wheels: Testing and Inspection
GENERAL PROCEDURE
Wheel runout should be measured with an accurate dial indicator. Measurements may be taken with the wheel installed on the vehicle, or off the
vehicle using an accurate mounting surface such as on a wheel balancer. Measurements may also be taken with or without the tire mounted on the
wheel.
Radial runout and lateral runout should be measured on both the inboard and outboard rim flanges. With the dial indicator firmly in position, slowly
rotate the wheel one revolution and record the total indicator reading. If any measurement exceeds specifications, and there is a vibration that wheel
balancing will not correct, the wheel should be replaced. Disregard any indicator readings due to welds, paint runs, scratches, etc.
