There are several possible causes for the squeaking noise from car door seals when driving on rough roads. Door-related noise: If you are unsure whether the noise is coming from the front or rear door, find a bumpy road to ensure the noise occurs at low speeds. While wearing a seatbelt and ensuring driving safety, slowly open the driver's side door and continue driving. If the noise persists, it indicates the rear door is the source. Have a passenger in the back perform the same test to confirm which door is making the noise. Seal rubber or door lock noise: Cut newspaper into 10 cm wide strips and place them between the seal and the door contact surface. Close the door tightly and drive to test. If the noise disappears, it indicates the sound is caused by friction from the seal rubber. If the noise remains, the seal rubber can be ruled out. Generally, cars within 3 years of use experience seal rubber noise. Door lock noise: Wrap a layer of black insulating tape around the door lock striker. Close the door tightly and drive. If the noise disappears, it confirms that the noise is caused by friction between the door lock hook and the striker.

From a car repair perspective, the squeaking noise from the door seals on rough roads is mainly caused by aging or deformation of the seals. The rubber material hardens and loses elasticity, causing friction with the door frame during bumps, which produces noise. Additionally, dust or small stones stuck in the gaps of the seals can create squeaking sounds when vibrating. Another reason is loose door hinges or slight deformation of the car body, which prevents the seals from tightly adhering to the frame, causing the gap to widen and produce impact noises during bumps. When encountering this issue, I recommend first checking the seals for cracks or dirt, cleaning them with a damp cloth, and applying some rubber lubricant. If the noise persists, it might be necessary to replace the seals. Avoiding rough roads can slow down the aging process, and regular maintenance of door components can also help prevent this issue.

As a long-time driver, I believe that squeaking from the seals is mostly caused by rubber wear or aging. Especially when driving on bumpy roads, the body shakes significantly, and the hardened seals rub against the door frame. My car has experienced this several times, and cleaning off accumulated dust or spraying some specialized lubricant usually quiets it down. Additionally, if the seals become too dry or brittle in low temperatures, they can also produce creaking sounds. To completely resolve the issue, it's necessary to check for any loose or damaged sections and consider replacing them. For daily maintenance, keeping the seals clean and avoiding prolonged exposure to sunlight or freezing conditions can help reduce the occurrence of squeaks.

I haven't been driving for long, and I find it quite annoying when the door seals squeak on rough roads. From what I understand, this is often due to the aging of the seals, surface cracking, or the rubber hardening, which causes friction and noise when bumping. Alternatively, dust and gravel can get stuck in them, creating noise during vibrations. The solution is simple: clean the seals with a damp cloth and then apply a small amount of lubricant. To prevent this, try to avoid dirt roads or clean the edges of the doors promptly.
