Solution

1. Tire Inspection and Correction

Sub-steps:
1. Check tire pressure using a tire pressure gauge; inflate to recommended PSI if low.
2. Inspect tires for uneven wear or visible damage; replace if necessary.
3. Rotate tires if uneven wear is detected to promote even wear patterns.

2. Wheel Lug Nut Check

Sub-steps:
1. Use a torque wrench to check the tightness of the wheel lug nuts.
2. Tighten any loose lug nuts to the manufacturer's specified torque (usually around 85 ft-lbs for most vehicles).

3. Driveshaft and Axle Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Visually inspect the driveshaft for any signs of damage or imbalance.
3. Inspect CV joints and axle boots for tears or leaks; replace if damaged.

4. Suspension Component Inspection

Sub-steps:
1. Examine suspension components (shocks, struts, control arms) for signs of wear or damage.
2. Use a pry bar to check for play in bushings and joints.
3. Replace any worn or damaged suspension parts.

5. Alignment Check

Sub-steps:
1. After any tire or suspension work, perform a wheel alignment.
2. Use alignment equipment to adjust the camber, caster, and toe settings to factory specifications.

Tools Required:

Tire pressure gauge
Torque wrench
