Solution

1. Tire Inspection and Balancing

Sub-steps:
1. Remove all four tires using a lug wrench.
2. Inspect each tire for irregular wear or damage.
3. Check tire pressure and inflate to the manufacturer-recommended PSI.
4. Mount tires on a tire balancer and balance them as necessary.
5. Reinstall tires and torque lug nuts to the manufacturer's specifications (typically 100-120 ft-lbs).

2. Wheel Alignment

Sub-steps:
1. Place the vehicle on an alignment rack.
2. Adjust the toe, camber, and caster settings according to manufacturer specifications.
3. Confirm alignment with a test drive to ensure straight tracking.

3. Suspension Components Inspection

Sub-steps:
1. Visually inspect struts and shocks for leaks or damage.
2. Check control arm bushings and ball joints for wear.
3. Replace any worn or damaged components as necessary.
4. Reassemble and ensure all bolts are tightened to their respective torque specifications.

4. Driveshaft and U-Joint Inspection

Sub-steps:
1. Inspect the driveshaft for any visible damage or corrosion.
2. Check U-joints for excessive play by attempting to move them by hand.
3. Replace any damaged driveshaft or U-joint components.
4. Reinstall driveshaft and ensure bolts are torqued to specifications.
