What Causes Door Squeaking?
2 Answers
Reasons for door squeaking: 1. Rusty door hinges; 2. Friction from door glass sealing strips; 3. Internal wiring harness hitting the door panel; 4. Dust entering the windshield, aging door seals; 5. Door deformation, improper door installation. Door design requirements include: 1. Ensuring passenger accessibility with maximum opening angle between 65 to 70 degrees; 2. No positional interference with other parts during opening; 3. Reliable locking when closed to prevent opening while driving; 4. Good sealing performance; 5. Large transparent area to meet lateral visibility requirements; 6. Sufficient strength and rigidity to ensure reliable operation, reduce vibrations, improve side collision safety, and prevent door sagging.
I find that door noises are quite common. As someone who enjoys tinkering with cars, I've encountered this issue several times. Possible causes include rusty door hinges that squeak when opening or closing—applying lubricant like WD-40 can solve this; or loose door lock mechanisms that rattle on bumpy roads, requiring screw tightening. Worn-out window regulator systems may also produce friction noises, while aged or deformed weatherstrips can create creaking sounds during operation. Debris like small stones stuck in door gaps or vibrating door pockets are frequent culprits too. A simple inspection method is shaking the door by hand to locate the source, followed by cleaning gaps and applying preventive lubricant. Don’t ignore it, as long-term neglect may accelerate part wear and compromise opening safety. Regular maintenance, such as quarterly lubrication, significantly reduces noise troubles.
