What Causes the Squeaking Noise in Door Hinges?

[DaisyLee]

Typically, the squeaking noise mainly originates from the door hinges and limiters. Due to years of opening and closing, the door hinges and limiters experience wear and tear, and dust accumulates in the gaps, leading to vibration interference during door operation, which results in the squeaking noise. Additional Information: 1. Recommendation: For new cars, it is advisable to visit the 4S dealership for inspection during your free time or the first maintenance. New cars theoretically should not have such issues. 2. Maintenance: The door and 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 regular maintenance. 3. Cleaning Dirt: Another component connecting the door and body is the door limiter, which allows the door to open to its maximum angle. After cleaning the grease and dirt from the limiter arm, pin shaft, and connecting bracket surfaces, apply an appropriate amount of lubricant to the upper and lower surfaces of the arm.
