1. Remove each wheel using a lug wrench.
2. Inspect tires for uneven wear patterns or damage.
3. If necessary, replace tires with new ones of the same size and specifications.
4. Reinstall wheels and torque lug nuts to the manufacturer's specifications (usually around 80-100 ft-lbs).

3. Wheel Balancing

Sub-steps:
1. Mount each tire on a wheel balancer.
2. Adjust weights as needed to achieve balance.
3. Reinstall balanced wheels onto the vehicle.

4. Suspension Inspection and Repair

Sub-steps:
1. Inspect all suspension components visually for signs of wear or damage.
