Adjust Alignment:
- Drive the vehicle onto an alignment rack.
- Follow the manufacturer’s specifications to adjust camber, caster, and toe angles.
- Test drive to ensure proper alignment.

4. Wheel Balancing

Balance Tires:
- Mount the tire on a wheel balancer.
- Add weights as needed to balance the tire/wheel assembly.
- Reinstall balanced tires on the vehicle and torque lug nuts.
