Where to Install Car Door Vibration Damping Pads?
3 Answers
Install them at the closest point between the door and the vehicle body panel when the door is closed. Below is relevant information about car door vibration damping pads: 1. Function: They prevent direct contact between the shock absorber and the vehicle body. When the car turns and the center of gravity shifts to one side, causing body tilt and spring compression, these pads provide support, thereby reducing vehicle roll. 2. Materials: The pads are made of paper, rubber sheets, or copper sheets, serving as sealing materials placed between two surfaces to enhance sealing. They act as sealing elements installed between static sealing surfaces to prevent fluid leakage. They are attached to the vehicle body using adhesive, and the adhesive materials are generally mild, so they won't cause damage to the vehicle body surface.
The door damping pad is usually attached to the limit points where the door contacts the car body. I've seen many people place it incorrectly, resulting in poor effectiveness. In fact, the optimal installation point is where the door collides with the car frame when fully opened. The specific location is near the hinge area on the door edge or the door frame pillar on the car body—you can press with your finger to feel the distinct metal collision point, which is the best spot for attachment. Remember to clean the surface with alcohol to remove grease before installation, then press firmly for 30 seconds to ensure adhesion. This small plastic pad not only eliminates the clanking noise when opening and closing the door but also prevents white impact marks on the door paint, especially useful for households with children who slam doors. It's recommended to check every six months and replace if the pad becomes hardened or aged.
The damping pad should be applied near the door stopper where the door contacts the car body. I recommend fully opening the door first to observe where the door edge touches the body frame—those contact points are the ideal sticking locations. In practice, the optimal position for most vehicle models is 3-5 cm below the door hinge or on the inner side of the B-pillar. Ensure to remove dust and car wax before application, otherwise the adhesive won’t hold properly. Though these cushioning pads may seem insignificant, they significantly reduce vibration noise when closing doors, especially for older cars frequently parked outdoors exposed to wind and sun. They also help prevent metal fatigue deformation. If you notice unusual noises when opening or closing the door, check this small accessory first to see if it has come loose.
