Solution

1. Preparation

Gather tools including a jack, jack stands, tire pressure gauge, and OBD-II scanner.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Inspection and Adjustment

Check Tire Pressure:
- Use a tire pressure gauge to measure pressure; adjust to manufacturer specifications.
Visual Inspection:
- Look for any cracks, punctures, or signs of bulging on the tires.
- Replace any damaged tires.

3. Wheel Balancing

Remove Tires:
- Loosen wheel nuts and lift the vehicle using a jack, securing it with jack stands.
- Remove each wheel.
Balance Wheels:
- Use a wheel balancer to check the balance of each wheel.
- Add weights as necessary to ensure proper balance.

4. Wheel Alignment

Alignment Check:
- Place vehicle on an alignment rack.
- Adjust toe, camber, and caster angles to meet factory specifications.

5. Suspension and Drivetrain Inspection

Inspect Suspension:
- Check all components, including control arms, bushings, and struts for wear or damage.
- Replace any worn components as needed.
Drivetrain Check:
- Inspect the driveshaft for any play or misalignment.
- Check the differential fluid level and condition; replace if necessary.
