Solution

1. Preparation

Gather tools: jack, jack stands, tire pressure gauge, torque wrench, wheel balancer, alignment machine.
Ensure the vehicle is on a flat, stable surface and the engine is turned off.

2. Tire Inspection and Maintenance

Check Tire Condition:
- Remove the tires using a socket set.
- Inspect each tire for bulges, excessive wear, or foreign objects.
- Replace any damaged tires if necessary.
Check Tire Pressure:
- Use a tire pressure gauge to measure the pressure in each tire.
- Inflate or deflate tires to the recommended pressure found in the owner’s manual or on the driver’s side door jamb.

3. Wheel Balancing

Balance Each Wheel:
- Mount the tires on a wheel balancer.
- Spin the wheels to check for balance and add weights as needed to achieve proper balance.

4. Suspension Inspection

Inspect Components:
- Visually inspect shocks, struts, and bushings for signs of wear or damage.
- If any components are worn, replace them with OEM or quality aftermarket parts.

5. Alignment Adjustment

Perform Wheel Alignment:
- Use an alignment machine to check and adjust the alignment settings.
- Adjust camber, caster, and toe settings according to OEM specifications.
