Sub-steps:
- Use a socket set to tighten any loose bolts on the heat shield and undercarriage panels.
- Ensure that exhaust components are securely mounted and not touching any other parts.
- Check the underbody for any foreign objects lodged in the components.

3. Tire and Wheel Inspection

Sub-steps:
- Remove each wheel using a socket set and inspect for any debris or damage.
- Check tire pressure and inspect for uneven wear patterns.
- Rotate or replace tires as necessary based on the inspection findings.

4. Drive Shaft and Axle Inspection

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Visually inspect the drive shaft and axles for any visible cracks or signs of wear.
- If any damage is found, proceed to disconnect the drive shaft using a socket set and replace it with a new one.

5. Suspension Component Inspection

Sub-steps:
- Inspect all suspension components for signs of wear, such as bushings, struts, and control arms.
- Replace any worn or damaged parts as necessary, using a torque wrench to ensure proper torque specifications during reinstallation.
