Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Safety warning: Ensure the engine is off and the keys are removed before starting.

2. Tire Inspection and Maintenance

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Check tire pressure using a tire gauge and inflate to recommended PSI.
3. Inspect the tread depth across all tires using a tread depth gauge.
4. Rotate tires if uneven wear is detected.

3. Wheel Balancing

Sub-steps:
1. Remove the wheels from the vehicle.
2. Mount each wheel on a wheel balancer.
3. Add wheel weights as required to achieve balance.
4. Reinstall the wheels ensuring they are torqued to the manufacturer specifications (typically 100-110 ft-lbs).

4. Suspension Component Inspection

Sub-steps:
1. Visually inspect shocks/struts for leaks or damage.
2. Check control arms, bushings, and tie rods for wear or play.
3. Replace any worn suspension components with OEM parts.
