What Are the Reasons for Loud Door Closing Sounds?
2 Answers
There are several reasons for loud door closing sounds, including poor door sealing and excessive force when closing the door. Below are detailed explanations and solutions: Poor door sealing: There is a sealing rubber strip on the inner side of the door, which affects the sound when closing the door. Since the rubber strip is a rubber product, it can age and harden, thereby affecting the door's sealing. When the door is closed, the sound becomes louder. In this case, replacing the rubber strip with a new one can reduce the noise when closing the door. Excessive force when closing the door: Many car owners use excessive force when closing the door, resulting in a loud sound. In fact, closing the door does not require much force—just enough to ensure the door is securely closed. Using too much force may loosen the hinges and limiters and even cause internal door components to fail. Methods to prevent loud door closing sounds: Install a door-closing buffer device: This is a rubber spring device attached to an appropriate position where the door closes. When the door is closed, the spring's buffering effect can reduce the deafening noise. However, the height of the spring should be appropriate, usually around 8mm. Alternatively, you can upgrade to an electric door closer, which does not require excessive force. Simply push the door to close, and it will automatically latch.
Having driven for over a decade, I've found that loud door-closing sounds are often related to usage habits. Some people slam doors too hard, making the handles clang loudly. New cars initially have buffers, but over time, the door hinges lack lubrication, causing squeaky noises when opening or closing. Aging and sagging sealing strips are also common—when the rubber hardens like stone, the door doesn't shut tightly. Misaligned door latches are even more troublesome; loose screws cause metal to hit metal directly, creating a particularly harsh sound. Additionally, if the soundproofing foam inside the door ages and falls off, closing the door just leaves the metal panel vibrating. I recommend regularly spraying WD-40 on the hinges, checking the elasticity of the seals, and avoiding slamming doors.
