1. Loose lug nuts: Ensure the lug nuts on the wheels are properly tightened. Loose lug nuts can cause the wheel to move slightly, resulting in a clanking sound when the car goes over bumps.
2. Worn suspension components: Worn-out suspension components, such as control arms, ball joints, or sway bar links, can cause a clanking sound when the car encounters uneven road surfaces.
3. Damaged exhaust system: A hole or leak in the exhaust system can cause a rattling or clanking sound, especially when driving over rough roads.
4. Spare tire: If the car has a spare tire mounted on the trunk or rear of the vehicle, ensure it is properly secured. A loose spare tire can move and make a clanking sound when driving.
5. Loose trunk latch: If the trunk latch is not properly closed, it can cause a rattling or clanking sound when driving.
6. Brake caliper: A loose brake caliper can cause a clanking sound when the car goes over bumps. Check if the brake caliper is properly bolted in place.
If you are unable to identify and resolve the issue on your own, it's recommended to have the car inspected by a qualified mechanic.
