Pinpoint Test
- CHECK FOR UNEVENLY LOADED VEHICLE
- 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 2 .
- CHECK THE TIRE PRESSURES AND TIRE CONDITIONS
- Check the tire pressures. Refer to the VEHICLE CERTIFICATION (VC) CODES label located on the driver door jamb. Check the tires for uneven/abnormal wear. REFER to WHEELS AND TIRES Wheels and Tires.
Are the tire pressures and tire conditions OK?
- Yes: GO to 3 .
- No: ADJUST the tire pressures to the specified pressure or INSTALL new tires as necessary.
- ISOLATE TIRE DRIFT/PULL CONDITIONNOTE: 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) .
- Cross the front wheel and tire assemblies from left-to-right. REFER to WHEEL AND TIRE .
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 AND TIRES Wheels and Tires to diagnose tire drift pull. If the vehicle drifts/pulls in the same direction, GO to 4 .
- No: Tire forces were causing the drift/pull and the concern has been corrected.
- CHECK FOR BRAKE DRAG
- Spin all 4 wheel and tire assemblies by hand and check for brake drag.
Do the wheels spin freely?
- Yes: GO to 5 .
- No: REFER to SYMPTOM CHART: BRAKE SYSTEM to diagnose brake drag condition.
- CHECK THE WHEEL ALIGNMENT
- Using alignment equipment and the manufacturer's instructions, check the wheel alignment.
Is the wheel alignment out of specification?
- Yes: ADJUST the alignment as necessary. REFER to Camber Adjustment - Front .
- No: REFER to SYMPTOM CHART: INTERACTIVE DIAGNOSTICS to diagnose steering system drift/pull/wander condition.
