Solution

1. Tire Inspection

Sub-steps:
- Remove the wheel covers if present.
- Inspect tires for bulges, cuts, or uneven wear patterns.
- Replace any damaged tires with new ones.

2. Wheel Balancing

Sub-steps:
- Remove the wheel and tire assembly from the vehicle.
- Take the tire to a tire shop and have it balanced using a dynamic balancing machine.
- Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications (usually around 80-100 ft-lbs).

3. Suspension Inspection

Sub-steps:
- Lift the vehicle using a jack and secure it on jack stands.
- Visually inspect the control arms, bushings, and tie rods for wear or damage.
- Replace worn suspension components as necessary.

4. Wheel Alignment

Sub-steps:
- Use an alignment rack to assess the alignment angles (camber, caster, toe).
- Adjust the angles to meet manufacturer specifications.
- Test drive the vehicle to confirm the alignment.
