- Remove the wheel using a socket set.
Balance Wheel:
- Mount the wheel on a tire balancing machine.
- Add weights as necessary to achieve balance according to machine specifications.
Reinstall Wheel:
- Torque the lug nuts to the manufacturer’s specified torque (usually around 100-150 ft-lbs).

4. Wheel Alignment

Setup Alignment Equipment:
- Position the vehicle on an alignment rack.
- Attach alignment sensors to wheels.
Adjust Alignment:
- Make necessary adjustments to camber, caster, and toe settings as per manufacturer specifications.
Test Drive:
- Once completed, take the vehicle for a test drive to verify alignment.

5. Suspension Inspection
