What Causes the Squeaking Sound When Opening the Car Door?
2 Answers
Squeaking sounds when opening the car door are mainly caused by wear and deformation of the door hinges and limiters, as well as dust and dirt adhering to the gaps. Due to years of opening and closing, the door hinges and limiters are prone to wear, and dust can accumulate inside, leading to vibrations and noise during the door operation. Over time, the door hinges may rust or deform. After cleaning the grease and dirt from the surfaces of the door hinges, limiter arms, limiter pins, and connecting brackets, it is advisable to apply a specialized lubricant for lubrication. The door and body are connected via hinges, and it is normal for hinges to produce noise after prolonged use. It is recommended to apply lubricant every 2 to 3 months for regular maintenance.
I've been driving for over twenty years, and squeaky car doors are nothing new—it's usually caused by rust or dirt buildup in the door hinges creating friction. With daily use, dust and rainwater inevitably get in there, and over time, the lack of lubrication between metal parts leads to that annoying squeak. But it's an easy fix. I recommend using a toothbrush or something similar to clean out the hinge gaps, then spraying some lubricant like WD-40 or regular motor oil. After spraying, open and close the door a few times to let it seep in. If the noise persists, the door check strap (which controls the door's opening and closing position) might be worn out and need replacement at a repair shop. Don’t ignore this issue—prolonged neglect can make the door harder to operate, and if it gets stuck, it could affect safe entry and exit. A quick clean and occasional lubrication during car washes can keep your doors smooth for years.
