Solution

1. Tire Inspection

Sub-steps:
1. Check tire pressure using a tire pressure gauge and inflate to manufacturer's specifications.
2. Visually inspect tires for uneven wear patterns; replace if necessary.
3. Rotate tires if uneven wear is detected to ensure even distribution.

2. Wheel Alignment and Balancing

Sub-steps:
1. Use a wheel alignment machine to check and adjust alignment angles.
2. Balance wheels using a wheel balancer to correct any imbalances.
3. Test drive to ensure vibrations are eliminated after adjustments.

3. Suspension Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Inspect shocks and struts for leaking fluid or physical damage; replace if needed.
3. Check bushings and control arms for wear; replace any that are cracked or deteriorated.

4. Driveshaft and CV Joint Inspection

Sub-steps:
1. Visually inspect the driveshaft for any noticeable damage or bent components.
2. Check CV joints for torn boots or grease leakage; replace if necessary.
3. Use a torque wrench to ensure all bolts are tightened to manufacturer specifications.
