Solution

1. Preparation

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

2. Inspect and Adjust Tires

Sub-steps:
- Check tire pressure and adjust to the manufacturer's specifications.
- Inspect the tires for uneven wear or visible damage; replace if necessary.
- Rotate tires if uneven wear is detected to promote even wear patterns.

3. Wheel Balancing

Sub-steps:
- Remove the wheels from the vehicle.
- Mount wheels on a tire balancing machine.
- Adjust weights as needed to balance each wheel.
- Reinstall wheels and torque to the manufacturer's specifications.

4. Inspect Driveshaft

Sub-steps:
- Raise the vehicle using a jack and secure it with jack stands.
- Visually inspect the driveshaft for any signs of damage or excessive play.
- If damaged, replace the driveshaft with a new unit, ensuring proper alignment during installation.

5. Check Engine and Transmission Mounts

Sub-steps:
- Inspect the mounts visually for cracks or signs of wear.
- Use a pry bar to check for excessive movement; if movement is detected, replace the mounts.
- Torque new mounts to the manufacturer's specifications.

6. Inspect Suspension Components

Sub-steps:
- Check shocks and struts for fluid leaks or physical damage.
- Inspect bushings for cracks or wear; replace if necessary.
- Replace any worn suspension components to restore stability.
