Solution

1. Tire Inspection and Replacement

Sub-steps:
- Remove the tires using a jack and lug wrench.
- Inspect each tire for uneven wear patterns, bulges, or punctures.
- If damage is found, replace the affected tires with OEM or quality aftermarket tires.

2. Wheel Balancing

Sub-steps:
- Mount the tires on a wheel balancing machine.
- Adjust weights as needed to ensure tires are properly balanced.
- Reinstall the balanced tires on the vehicle, tightening the lug nuts to the manufacturer’s torque specifications (typically around 80-100 ft-lbs).

3. Wheel Alignment

Sub-steps:
- Drive the vehicle onto an alignment rack.
- Adjust the camber, caster, and toe settings according to the manufacturer's specifications.
- Confirm that the steering wheel is centered after alignment adjustments.

4. Suspension Inspection and Repair
