Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Tire Inspection and Replacement

Check Tire Pressure
- Use a tire pressure gauge to check each tire.
- Inflate to the recommended PSI levels as indicated on the driver’s side door jamb.
Inspect Tires for Damage
- Look for any visible signs of damage or uneven wear.
- Replace any damaged tires with new ones if necessary.

3. Wheel Balancing

Remove Wheels
- Use a lug wrench to loosen and remove the lug nuts.
- Take off the wheels and place them on a wheel balancer.
Balance Each Wheel
- Add weights as necessary to achieve proper balance.
- Reinstall the wheels and torque the lug nuts to the manufacturer's specifications (typically around 80-100 ft-lbs).

4. Suspension and Alignment Check

Inspect Suspension Components
- Use a jack to lift the vehicle and inspect control arms, bushings, and shocks for wear.
- Replace any worn components.
Perform Wheel Alignment
- Use an alignment machine to check and adjust the toe, camber, and caster angles according to manufacturer specifications.
