If misalignment is found, adjust the camber, caster, and toe settings according to the specifications in the repair manual.

4. Replace Worn Suspension Components

Tools Required: Socket set, wrenches, jack, jack stands
Remove any damaged components (e.g., control arms, bushings, struts).
Replace with OEM or quality aftermarket parts, ensuring proper torque specifications are followed.

5. Rotate Tires

Tools Required: Jack, jack stands, lug wrench
Remove tires from the vehicle and rotate them according to the pattern recommended in the owner’s manual.
Reinstall the tires, tightening lug nuts to the specified torque.
