1. Visually inspect the exhaust system from the manifold to the tailpipe for any visible cracks or leaks.
2. Check for loose hangers or brackets that may cause rattling.
3. If a leak is found, replace the damaged section of the exhaust or tighten loose components.

3. Engine Mount Inspection

Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Inspect the engine mounts for any visible cracks or degradation.
3. If an engine mount is damaged, remove the old mount using a socket set and replace it with a new one, following torque specifications from the service manual.

4. Air Intake System Examination

Sub-steps:
1. Check the air intake hose for any cracks or loose clamps that may cause abnormal noise.
2. Tighten any loose clamps or replace damaged hoses as necessary.

5. Drive Belt Inspection

Sub-steps:
