Remove the wheel covers or hubcaps if necessary and loosen the lug nuts.
Jack up the vehicle and secure it on jack stands.
Remove the wheels and inspect for uneven wear; rotate tires if necessary to promote even wear.

4. Alignment Check and Adjustment

Set the vehicle on an alignment rack.
Check and adjust the front and rear alignment settings according to manufacturer specifications.
Make adjustments to camber, caster, and toe as necessary using alignment tools.
