Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, flashlight.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.

2. Inspect Trim and Interior

Sub-steps:
- Open all storage compartments and shake any loose items.
- Check door panels and dashboard for loose screws or clips.
- Tighten any loose screws or clips with the appropriate tool.

3. Examine Suspension System

Sub-steps:
- Lift the vehicle using the jack and secure it with jack stands.
