|
Release the parking brake to avoid an incorrect measurement.
|
|
2.
|
Make sure the suspension is not modified.
|
|
3.
|
Make sure the fuel tank is full, and that the tire repair kit,
the spare tire, the jack, and the tools are in place on the vehicle.
|
|
4.
|
Check the tire size and tire pressure according to tire information.
|
|
|
|
Use commercially available computerized four wheel alignment
equipment to measure wheel alignment (caster, camber, toe, and turning
angle). Follow the equipment manufacturer's instructions.
|
|
