4. If any tires are found to be damaged, replace them with new tires of the same specifications.

3. Wheel Balancing

Sub-steps:
1. Take the wheels to a tire shop for balancing.
2. Mount each wheel on a balancing machine, and add weights as necessary to achieve balance.
3. Reinstall the balanced wheels back onto the vehicle.

4. Alignment Adjustment

Sub-steps:
1. Use an alignment tool or take the vehicle to a professional alignment shop.
2. Adjust the camber, caster, and toe angles as per the manufacturer's specifications.
3. Test drive the vehicle after alignment to ensure the steering wheel is centered.
