Four Wheel Alignment Check: Procedure
- Make sure the tire pressures are to specification.NOTE: Use the tire sticker values displayed on the door jamb. If unavailable, use these values:
- 18 inch wheels - 42 psi
- 19 inch wheels - 42 psi
- 20 inch wheels - 42 psi
- Make sure that the alignment rack slip/turn plates are locked.
- Disconnect the charging cable from the vehicle.WARNING: Do not attach the charging cable to the charge port while the vehicle is on the rack.
- Drive the vehicle onto the alignment rack, and stop the vehicle approximately 6 inches before the turn plates to allow for rolling compensation.
- Shift into Park.
- Install wheel chocks.
- From outside of the vehicle, fasten the driver and front passenger seat belts, and shift into Neutral.
- Pass a shop towel halfway through the both door strikers, and use a pen to latch the doors.
- Raise the alignment rack to a working height and slightly lower to lock.

- Perform a rolling compensation and manually position the vehicle onto the slip/turn plates.
- Reinstall the wheel chocks.
- Remove the alignment slip/turn plate pins.
- If necessary, calibrate the ride height measurement tool.
- Use a tape measure to measure the height of the tool.
- If necessary, adjust the metal knob to compensate for the height of the tool (i.e., the tool should read "0 mm" after adding the height of the tool).
- Measure the ride height at 4 locations which are an additional 75 mm towards the centerline from the vehicle lifting points.
- Check that the vehicle's ride height is within specifications. See WHEEL ALIGNMENT .
- Install the brake pedal depressor and steering wheel bubble leveler.
- Perform a caster sweep, center and set the steering wheel using the bubble leveler and steering wheel holder.
- Print the vehicle alignment summary and verify that the alignment parameters are within specifications.
- If the parameters are not within specifications, discontinue this procedure and perform a four wheel alignment adjustment. See FOUR WHEEL ALIGNMENT CHECK AND ADJUSTΒ .NOTE: Add the adjustment to the Repair Order/Service Visit as an additional line item/activity.
- Remove the alignment heads from the wheels.
- Remove the brake pedal depressor.
- Install the alignment slip/turn plate pins.
- Lower the alignment rack to the ground.
- Unlatch the driver's door, shift into Park, and remove the steering wheel bubble leveler.
