Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, torque wrench, and tire balancer.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Tire Balancing

Remove the wheel from the vehicle using a lug wrench.
Mount the wheel on a tire balancing machine.
Adjust weights on the wheel as indicated by the balancer to achieve proper balance.
Reinstall the wheel, tightening lug nuts to the manufacturer's specified torque.

3. Tire Inspection and Replacement

Inspect all tires for uneven wear, bulges, or damage.
If tires are worn unevenly, rotate or replace them as necessary.
Ensure the tire pressure is set to the manufacturer’s specifications.

4. Suspension Component Inspection

Check shocks and struts for leaks or damage.
Replace any worn or damaged suspension components.
Re-torque any loose bolts to the specified torque values using a torque wrench.

5. Wheel Bearing Inspection

Raise the vehicle and support it securely with jack stands.
Grasp the wheel at the 12 and 6 o’clock positions and check for play.
If there is movement, replace the wheel bearing as necessary.

6. Driveshaft and Universal Joint Inspection

Inspect the driveshaft for any signs of damage or imbalance.
Check universal joints for play or wear; replace if necessary.
