Solution

1. Tire Inspection and Inflation

Sub-steps:
- Check tire pressure using a tire gauge; inflate tires to the recommended PSI.
- Visually inspect tires for bulges, cracks, or foreign objects embedded in the tread.
- Replace any damaged tires as necessary.

2. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle using a socket set.
- Take wheels to a tire shop for professional balancing.
- Reinstall wheels, ensuring nuts are torqued to the manufacturer's specifications (typically 80-100 ft-lbs).

3. Wheel Alignment

Sub-steps:
- Use an alignment machine at a professional shop to assess the alignment angles.
- Adjust camber, caster, and toe to meet factory specifications as needed.

4. Suspension Inspection

Sub-steps:
- Lift the vehicle using a jack and securely place it on jack stands.
- Inspect struts and shocks for leaks or signs of wear, replacing if necessary.
- Check bushings and control arms for damage and replace any worn components.
