4. Reinstall the wheels and torque the lug nuts to the manufacturer's specification (usually around 100-120 lb-ft).

3. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
2. Have a four-wheel alignment performed to ensure all angles are within specification.
3. Adjust camber, caster, and toe as necessary based on the alignment report.

4. Wheel Balancing

Sub-steps:
1. Remove the wheels again if they were not balanced previously.
2. Take the wheels to a tire shop for dynamic balancing.
3. Ensure that weights are correctly applied to each wheel as needed.
4. Reinstall the wheels and torque the lug nuts.

5. Suspension and Steering Inspection

Sub-steps:
