Solution

1. Preparation

Tools Required: Tire pressure gauge, jack, jack stands, wheel balancer.
Gather all necessary tools and park the vehicle on a flat, stable surface.

2. Tire Inspection

Sub-steps:
1. Remove the wheel covers (if applicable).
2. Check each tire for visible damage or bulges.
3. Measure tread depth using a tread depth gauge.
4. Inspect for uneven wear patterns, indicating potential alignment or balance issues.

3. Tire Balancing

Sub-steps:
1. Remove the wheels from the vehicle using a jack and jack stands.
2. Mount each wheel on a wheel balancer.
3. Follow the machine instructions to balance the wheels.
4. Add balancing weights as needed and recheck for balance.

4. Adjust Tire Pressure

Sub-steps:
1. Use a tire pressure gauge to check the pressure of all four tires.
2. Inflate or deflate tires to the recommended pressure specified in the owner's manual.
3. Recheck tire pressure after adjustments.

5. Suspension and Alignment Check

Sub-steps:
1. Inspect suspension components such as struts, shocks, and control arms for wear or damage.
2. If any components are worn, replace them.
3. Perform a wheel alignment using an alignment machine, adjusting camber, caster, and toe angles to manufacturer specifications.
