Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to secure the vehicle.

2. Tire Inspection

Sub-steps:
1. Remove the wheel covers or hubcaps if applicable.
2. Inspect tires for visible damage, such as cracks, bulges, or punctures.
3. Check tire pressure with a gauge and inflate to the recommended PSI.
4. Measure tread depth using a tread depth gauge; ensure it meets legal limits.

3. Wheel Balancing

Sub-steps:
1. Remove the wheel from the vehicle using a socket set.
2. Take the wheel to a tire shop for professional balancing.
3. Reinstall the wheel once balancing is confirmed.

4. Wheel Alignment

Sub-steps:
1. Use an alignment machine (available at most automotive shops) to check alignment specifications.
2. Adjust camber, caster, and toe settings as needed to meet manufacturer specifications.
3. Test drive the vehicle to ensure steering is centered.

5. Suspension Inspection

Sub-steps:
1. Visually inspect suspension components for signs of wear, such as cracked bushings or leaking shocks.
2. Replace any worn components with OEM equivalents.
3. Test drive the vehicle to assess the impact of repairs.
