Solution

1. Tire Inspection and Replacement

Sub-steps:
1. Remove the wheel covers if applicable and inspect all tires for damage or uneven wear.
2. Use a tire pressure gauge to check and adjust tire pressures as needed.
3. If tires are worn or damaged, replace them with new ones of the same specifications.

2. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a socket set.
2. Mount the wheels on a tire balancing machine to check for imbalances.
3. Add weights to balance the wheels according to the machine's recommendations.
4. Reinstall the wheels and torque the lug nuts to the manufacturer’s specifications (typically 100-150 ft-lbs).

3. Suspension Component Replacement

Sub-steps:
1. Inspect and remove any worn or damaged suspension components.
2. Replace shocks or struts if they show signs of leaking or wear.
3. Use a torque wrench to install new components, following manufacturer specifications.

4. Alignment Adjustment

Sub-steps:
1. Drive the vehicle to an alignment shop or use an alignment tool.
2. Adjust camber, caster, and toe angles to align them with the manufacturer’s specifications.
3. Test drive to ensure the vehicle tracks straight and vibrations are eliminated.
