Solution

1. Tire Pressure Adjustment

Check the tire pressure using a tire gauge.
Inflate or deflate tires to the manufacturer's specified pressure (found on the driver’s side door jamb).
Recheck pressure after adjusting.

2. Tire Inspection and Replacement

Remove the wheels using a socket set.
Inspect each tire for uneven wear, bulges, or cracks.
Replace any damaged tires with new ones if necessary.
Ensure replacement tires are of similar size and tread pattern.

3. Wheel Balancing

Mount the tires on a wheel balancer to identify any imbalances.
Adjust weights on the rim as needed to achieve balance.
Reinstall the balanced wheels securely.

4. Wheel Alignment

Use an alignment rack to check toe, camber, and caster angles.
Adjust alignment settings to meet manufacturer specifications.
Test drive the vehicle to ensure alignment is correct.

5. Suspension Inspection

Inspect all suspension components for wear or damage, including bushings, shocks, and struts.
Replace any worn or damaged components using appropriate tools (e.g., socket set, torque wrench).
Ensure all bolts are tightened to the manufacturer's torque specifications.

6. Driveshaft and Axle Inspection

Inspect driveshaft for any signs of wear, including vibrations or noise.
If damaged, replace the driveshaft.
Check axle integrity; replace if any issues are found.
