How to Solve the Abnormal Noise When Opening and Closing Car Doors?

[BradleyDella]

Solutions for abnormal noise when opening and closing car doors: 1. Check if the door seal is aged, and replace the seal if necessary; 2. Check for any foreign objects in the door gaps, and clean them if found; 3. If the noise is caused by loose fastening between door components, tightening the screws can solve the problem; 4. If the noise results from insufficient body stiffness or welding detachment causing friction between steel plates, it is recommended to seek repair at a maintenance shop. The design requirements for car doors include: 1. Ensuring ease of passenger entry and exit, with the opening angle controlled between 65 to 70 degrees; 2. No positional interference with other parts during the opening process; 3. Reliable locking when the door is closed, preventing it from opening while driving; 4. Good sealing performance; 5. A large transparent area to meet lateral visibility requirements; 6. Sufficient strength and stiffness to ensure reliable door operation, reduce door vibration, enhance vehicle side collision safety, and prevent door sinking.
