Pinpoint Test

  1. CHECK FOR UNEVENLY LOADED VEHICLE
    1. Visually check the vehicle for an uneven loading condition.
    • Is the vehicle unevenly loaded? 
    • Yes:  ADVISE the customer of uneven loading condition.
    • No:  GO to step 2 .
  2. CHECK THE TIRE PRESSURES AND TIRE CONDITIONS
    1. Check the tire pressures. Refer to the VEHICLE CERTIFICATION (VC) LABEL LOCATOR on the driver door jamb. Check the tires for uneven/abnormal wear. REFER to WHEELS & TIRES .
    • Are the tire pressures and tire conditions OK? 
    • Yes:  GO to step 3 .
    • No:  ADJUST the tire pressures to the specified pressure or INSTALL new tires as necessary.
  3. ISOLATE TIRE DRIFT/PULL CONDITION
    NOTE: It is important to determine if tire forces are the cause of a drift/pull condition. Changing the position of the wheel and tire assemblies on the vehicle may correct a drift/pull condition, however the tire drift/pull may return if the wheel and tire assemblies are repositioned during future service. A tire or tires that are causing a drift/pull should not be removed from service unless it has been determined that the tire(s) are worn beyond specification. REFER to Symptom Chart(s) .
    1. Cross the front wheel and tire assemblies from left-to-right. REFER to WHEELS & TIRES .
      • Does the vehicle drift/pull? 
      • Yes:  If the vehicle drifts/pulls in the opposite direction, tire forces are causing the drift/pull. REFER to WHEELS & TIRES to diagnose tire drift pull. If the vehicle drifts/pulls in the same direction, GO to step 4 .
      • No:  Tire forces were causing the drift/pull and the concern has been corrected.
    2. CHECK FOR BRAKE DRAG
      1. Spin all 4 wheel and tire assemblies by hand and check for brake drag.
      • Do the wheels spin freely? 
    3. CHECK THE WHEEL ALIGNMENT
      1. Using alignment equipment and the manufacturer's instructions, check the wheel alignment.
      • Is the wheel alignment out of specification?
