What Causes the Squeaking Noise When Opening the Car Door?
2 Answers
The reasons for the squeaking noise when opening the car door are: 1. Rusty door hinges; 2. Friction from the door glass sealing strip; 3. Internal wiring harness hitting the door panel; 4. Dust accumulation on the windshield or aging door sealing strips; 5. Door deformation or improper installation. The design requirements for car doors include: 1. Ensuring passenger accessibility with a maximum opening angle of approximately 65 to 70 degrees; 2. Avoiding positional interference with other parts during opening; 3. Reliable locking when closed to prevent accidental opening while driving; 4. Excellent sealing performance; 5. Sufficient transparent area to meet lateral visibility requirements; 6. Adequate strength and rigidity to ensure reliable operation, reduce door vibration, enhance side collision safety, and prevent door sagging.
When opening the car door, I've heard strange noises several times myself. Most often, it's because the door hinges lack lubrication. In humid weather, metal tends to rust, making that annoying creaking sound when opening the door. Additionally, if the door latch is worn, it might produce a clicking noise; broken support rods like hydraulic struts can cause a hissing sound; and aging door seals or loose internal wiring harnesses could also be culprits. I recommend buying some WD-40 to spray on the hinges or latches—it's an easy fix. If the problem persists, take your car to a repair shop immediately to avoid long-term damage to the door structure. After parking, regularly clear debris from door gaps to prevent such issues. Remember, small noises can escalate into big problems—addressing them early saves both hassle and money.
