Solution

1. Preparation

Gather tools and safety gear.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Inspect and Maintain Tires

Sub-steps:
- Check tire pressure using a tire pressure gauge; inflate to manufacturer specifications if necessary.
- Visually inspect tires for bulges, cracks, or uneven wear patterns.
- If tires are worn unevenly, consider rotating or replacing them.

3. Wheel Balancing

Sub-steps:
- Remove the wheel from the hub using a socket set.
- Mount the wheel on a balancing machine to check for imbalances.
- Add weights to the rim as necessary to achieve balance.
- Reinstall the wheel and torque lug nuts to the manufacturer's specifications (usually around 80-100 ft-lbs).

4. Inspect Suspension Components

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Visually inspect suspension components for any signs of wear or damage, focusing on bushings, ball joints, and struts.
- Replace any worn or damaged components with OEM parts.

5. Alignment Check

Sub-steps:
- Use an alignment tool to check the angles of the wheels.
- Adjust as necessary to bring the vehicle back into specification.
- Test drive to confirm the handling is restored.

6. Driveshaft and CV Joint Inspection

Sub-steps:
- Inspect the driveshaft for any signs of damage or excessive play.
- Check the CV joints for wear and ensure the boots are intact.
- Replace any damaged parts as needed.
