3. Check Engine Mounts

Sub-steps:
1. Locate the engine mounts (typically found on the front and rear of the engine).
2. Use a jack to slightly lift the engine for better access.
3. Inspect the mounts for cracks or separation of rubber from metal. Replace if necessary.

4. Examine Suspension Components

Sub-steps:
1. Inspect the struts, shocks, and sway bar links for any looseness or wear.
2. Use a torque wrench to tighten any loose fasteners to manufacturer specifications.
3. Replace any worn components, such as struts or bushings.

5. Final Assembly

Sub-steps:
1. Recheck all components to ensure they are secure.
2. Remove the jack and lower the engine if it was lifted.
3. Test the vehicle to ensure the rattling noise has been resolved.
