What Causes the Abnormal Noise When Opening and Closing Car Doors?
3 Answers
Abnormal noises when opening and closing car doors mainly originate from wear and tear on the door hinges and limiters. Due to years of use, the door hinges and limiters may wear out or accumulate dust in the gaps, causing vibrations and resulting in abnormal sounds during door operation. Here is an introduction to car doors: 1. The door and the car body are connected via hinges, and it is normal for hinges to produce noise after prolonged use. To ensure the hinges remain smooth and quiet, apply lubricating oil every 2-3 months for maintenance. 2. Additionally, the door and the car body are connected by another component called the door limiter. To maintain it, open the door to its maximum angle, clean the grease and dirt from the limiter arm, pivot pin, and connecting bracket surfaces, and then apply an appropriate amount of grease to the upper and lower surfaces of the arm. 3. If the car has been in use for some time, check whether the door seals have aged. Since seals are made of rubber, they will gradually deteriorate and crack over time, leading to noticeable wind noise and friction sounds for passengers. If the seals are aged or damaged, it is recommended to replace them directly. Also, regularly clean dust and rainwater from the gaps between the seals during routine use to prevent aging.
Every time I drive my old car, I hear the doors creaking and it's really annoying. I did some research and found that the most common cause is rust and lack of oil in the door hinges. Last time I went to the repair shop, the mechanic used a grease gun to lubricate the hinges, and the noise stopped immediately. Now, I use WD40 to spray and maintain the hinges every month, especially making sure the drainage holes aren’t blocked after the rainy season. Aging door seals can also be a problem—my neighbor’s car door seal cracked, making a tearing sound like adhesive tape when opening or closing the door, but it became quiet after replacing the new seal. If there’s a metal clanging sound, it might be loose screws in the door stopper, which need to be tightened promptly. Door noises shouldn’t be ignored—last time I saw someone on the forum whose hinge rusted so badly it deformed the door frame, and the repair was very expensive.
Having driven a taxi for over a decade, I've handled no less than eighty cars. I've seen countless cases of door squeaks, so let me share some experience: 70% are due to hinge lubrication issues, especially in older cars where the grease emulsifies and fails after rainy seasons—applying high-temperature grease can fix it; cracked sealing strips produce a rustling sound, and buying specialized rubber conditioner on Taobao can extend their lifespan; worn limiters are the main cause of clicking noises—take them apart to check for metal debris; modified doors are the trickiest—once a customer installed ambient lighting and the wiring got stuck in the hinge. For DIY fixes, buy a can of silicone-based door lubricant, clean dust before spraying, and open/close the door a dozen times to spread the film evenly. Prevention is simple: don’t forget to dry door seams after washing, and lubricate hinges every six months.
