- If damage is found on exhaust components, replace as necessary.

3. Examine Suspension Components

Sub-steps:
- Raise the vehicle using a jack and place jack stands for safety.
- Inspect struts, shocks, and springs for signs of wear, such as rust or oil leaks.
- Replace any worn components with OEM parts if necessary.
- Tighten all suspension bolts to the specified torque settings.

4. Check for Loose Panels or Components

Sub-steps:
- Inspect the undercarriage, wheel wells, and engine bay for any loose panels or covers.
- Re-secure any loose parts with appropriate fasteners or clips.
- For interior rattles, check the dashboard and console for loose screws or clips.
