What Causes the Squeaking Noise from Car Door Seals?
2 Answers
The reason for the squeaking noise from car door seals is: aging of the sealing rubber. Other causes of car door squeaking include: 1. Foreign objects inside the door trim panel; 2. Loose interior trim panel or audio system; 3. Rusty door hinges; 4. Poor contact or inadequate lubrication of the door lock mechanism. Car doors provide access for drivers and passengers, isolate external disturbances, and to some extent mitigate side impacts to protect occupants. Solutions for car door squeaking include: 1. Adjusting the door gap size; 2. Adjusting the door height; 3. Adjusting the door tension; 4. Replacing the door sealing rubber; 5. Applying an appropriate amount of grease on the arm rod surface; 6. Replacing the door stopper.
The causes of car door seal noise are quite common. From what I've observed in many vehicles, this sound is mostly due to the aging and hardening of the seals, which creates friction noise when opening and closing doors. Another reason is the accumulation of dust or dirt in the gaps, causing squeaking sounds when rubbed. Some cases are caused by significant weather changes, where the rubber contracts and expands, producing abnormal noises. For a simple solution, you can first clean the seals with a damp cloth and then spray some silicone-based lubricant, which often quiets them down. If that doesn't work, the seals might be cracked and need replacement at a repair shop. Regular maintenance of rubber components can prevent this issue, especially during humid seasons.
