Solution

1. Tire Inspection

Sub-steps:
1. Remove the wheel covers if applicable.
2. Inspect tires for uneven wear patterns or visible damage.
3. Check tire pressure with a gauge and inflate as necessary to the recommended PSI.

2. Wheel Balancing

Sub-steps:
1. Remove the wheel from the vehicle using a lug wrench.
2. Mount the wheel on a wheel balancer.
3. Adjust weights to achieve proper balance based on the balancer's readings.
4. Reinstall the wheel and torque lug nuts to the manufacturer’s specifications (typically 80-100 ft-lbs).

3. Suspension Component Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Visually inspect control arms, bushings, and shock absorbers for wear or damage.
3. Replace any worn or damaged components with OEM parts.

4. Wheel Alignment

Sub-steps:
1. Take the vehicle to an alignment shop with a professional alignment machine.
2. Follow the technician's recommendations for adjusting camber, caster, and toe settings.
3. Confirm alignment is within manufacturer specifications.

5. Brake Component Inspection

Sub-steps:
1. Remove the wheel to access brake components.
2. Inspect brake rotors for warping or uneven wear.
3. Replace warped rotors with new ones and ensure proper installation of brake pads.
