Solution

1. Tire Inspection

Sub-steps:
1. Check the tire tread depth using a tread depth gauge.
2. Inspect for any bulges, cuts, or other damage on the tire surface.
3. Ensure all tires are inflated to the manufacturer's recommended pressure.
Tools Required: Tire pressure gauge, tread depth gauge.

2. Wheel Balancing

Sub-steps:
1. Remove the wheel and tire assembly from the vehicle.
2. Use a wheel balancer to check for imbalance.
3. Add wheel weights as necessary to achieve proper balance.
4. Reinstall the wheel and torque lug nuts to the manufacturer's specifications (typically 85-100 ft-lbs).
Tools Required: Wheel balancer, torque wrench.

3. Suspension Inspection

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Visually inspect the suspension components for any signs of wear, such as cracked bushings or leaking struts.
3. Replace any damaged components as necessary.
Tools Required: Jack, jack stands, basic hand tools.

4. Driveshaft Examination

Sub-steps:
1. Inspect the driveshaft for any visible bends or damage.
2. Check for loose or damaged universal joints.
3. Replace the driveshaft or U-joints if any issues are found.
Tools Required: Basic hand tools, possibly a torque wrench.

5. Wheel Alignment

Sub-steps:
1. Take the vehicle to a professional alignment shop.
