Solution

1. Tire Inspection

Sub-steps:
- Use a tire pressure gauge to check tire pressures; adjust to manufacturer specifications.
- Inspect each tire for bulges, cuts, or uneven tread wear.
- Rotate tires if uneven wear is detected, following the recommended rotation pattern.

2. Wheel Balancing

Sub-steps:
- Remove the wheel and tire assemblies from the vehicle.
- Mount each wheel on a wheel balancer.
- Add weights as necessary to balance each wheel according to specifications.
- Reinstall the wheels back onto the vehicle, ensuring proper torque specifications (typically 80-100 ft-lbs depending on model).

3. Suspension Inspection

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Inspect control arms, tie rods, and bushings for signs of wear or damage.
- Replace any worn components as necessary, using OEM parts where recommended.

4. Wheel Alignment

Sub-steps:
- Use a professional alignment machine to check the alignment settings.
- Adjust the camber, caster, and toe settings to meet manufacturer specifications.
- Test drive the vehicle to ensure alignment is correct.
