Solution

1. Tire Inspection and Balancing

Sub-steps:
1. Check tire pressure using a tire gauge; inflate to manufacturer specifications if necessary.
2. Inspect each tire for uneven wear, bulges, or punctures.
3. If tires are unbalanced, take the vehicle to a tire shop to have them balanced properly.

2. Wheel Alignment

Sub-steps:
1. Drive the vehicle to a professional alignment shop.
2. Perform a four-wheel alignment according to manufacturer specifications.
3. Adjust camber, toe, and caster angles to ensure they are within the recommended range.

3. Suspension Component Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Inspect the shocks and struts for leaks or damage.
3. Check all bushings for wear; replace any that are cracked or excessively worn.

4. Driveshaft and U-Joint Inspection

Sub-steps:
1. Inspect the driveshaft for any signs of damage or imbalance.
2. Check the U-joints for play; if there is excessive movement, replace them.
3. Ensure that all mounting bolts for the driveshaft are tight and in good condition.
