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 . 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 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.

Last week, I just dealt with the door squeaking issue and learned a lot from the mechanic. First, identify the sound type: a creaking sound is likely due to hinge problems, while a clicking noise may indicate a damaged stopper. For inspection, try spraying WD40 on the hinges first; if that doesn’t work, remove the interior trim to check the wire harness clips. Aging rubber seals are often overlooked, especially the fuzzy seals at the bottom of the door, which can rub against the door frame when cracked. The repair shop showed me a typical case: a car’s door drainage holes got clogged after driving through water, leading to corrosion of the stopper spring, costing over 600 yuan to replace. Now, I regularly check the elasticity of the door seals and use a flashlight to inspect hinge grease buildup. Even new cars aren’t immune—last year, a customer found the vibration damper had shifted during factory assembly upon delivery.

Recently, there's always been a squeaking sound when opening and closing the car door, so I took it to an auto repair shop for a full inspection. Hinge wear is the most common cause, especially for cars frequently parked under trees, as tree sap mixed with dust forms an abrasive. The mechanic taught me to use an endoscope to check hinge pin wear and also cleaned the drainage hole sludge. Hardened weatherstrips can produce cracking sounds, which can be treated with rubber softener. If you hear a metal knocking sound, it's most likely an issue with the door check strap—in my case, a small ball bearing was missing from the check strap, and replacing the part cost 200. After the repair, the mechanic applied Teflon tape between the weatherstrip and door frame to reduce friction. It's recommended to lubricate door components every 20,000 kilometers and avoid directly spraying hinges with high-pressure water during car washes. A fellow car owner didn't address the issue in time, leading to door panel deformation and costing over a thousand in repairs.

Both of my family's cars have experienced door rattling issues. The older SUV had rusty hinges, which were fixed with grease; the newly purchased sedan, on the other hand, had squeaky rubber noises due to the fresh and hard sealing strips. A car repair friend provided practical solutions: buy a specialized white hinge grease, which lasts longer than regular grease; rubber conditioner can soften the seals, but don’t apply too much to avoid attracting dust. The most troublesome is the limit switch rattle, which requires removing the door panel for repair. There are tricks to identifying the source of the noise: sounds from the top come from hinges, the middle suggests sealing strips, and the bottom points to the limit switch. Preventive tips: dry the seal grooves after washing the car, reapply grease to hinges annually, and avoid hanging heavy items on the door frame. Once, I forgot to close the sunroof during rain, causing oxidation in the door wiring harness connectors, which also to rattling.
