What Causes the Door Seal to Squeak When Driving on Rough Roads?

[VanSophie]

There are several possible reasons for the squeaking sound from the door seal when driving on rough roads. Door Squeaking: If you're unsure whether the noise is coming from the front or rear door, find a rough road section to ensure the sound occurs at low speed. With the seatbelt fastened 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 squeaking. Seal Rubber or Door Lock Squeaking: Cut newspaper into 10 cm wide strips and place them between the seal and the door contact surface in sections. Close the door tightly and drive to test. If the noise disappears, it indicates friction from the seal rubber. If the noise persists, the seal rubber can be ruled out. Generally, cars within 3 years of use experience seal rubber squeaking. Door Lock Squeaking: Wrap a layer of insulating black tape around the door lock striker. Close the door tightly and drive. If the noise disappears, it confirms that the squeaking is caused by friction between the door lock hook and the striker.
