Solution

1. Preparation

Gather tools: Jack and jack stands, tire pressure gauge, torque wrench, OBD-II scanner, wheel balancer.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Tire Inspection and Adjustment

Sub-steps:
- Use a tire pressure gauge to verify that all tires are inflated to the manufacturer's recommended pressure.
- Inspect tires for uneven wear patterns, bulges, or damage. Replace if necessary.
- If uneven wear is found, rotate tires according to the manufacturer's specifications.

3. Wheel Balancing

Sub-steps:
- Remove the wheel from the vehicle using a socket set.
- Mount the wheel on a dynamic balancing machine.
- Adjust the wheel weight according to the machine's readings to ensure it is properly balanced.
- Reinstall the wheel and torque the lug nuts to the manufacturer's specified torque.

4. Drivetrain Inspection

Sub-steps:
- Inspect the driveshaft for any visible damage or looseness.
- Check the universal joints for wear and proper lubrication.
- If damage is found, replace the affected components.

5. Suspension Components Check

Sub-steps:
- Visually inspect all suspension components, including bushings, shocks, and struts for signs of wear or damage.
- Replace any worn or damaged components as needed.
