What Causes the Squeaking Noise in the Edge Door Stopper?

[AmirFitz]

Below are the reasons for the squeaking noise: Reason: The door hinge axis and the stopper rotation axis are severely misaligned; it is recommended that the angle between the door hinge axis and the stopper rotation axis must be controlled to less than 3 degrees, and the door hinge should be monitored. Improper Installation: Some squeaking noises are caused by improper installation, and others result from wear due to improper assembly during use or door sagging. Troubleshooting such issues is relatively simple: loosen all the stopper mounting screws, open and close the door repeatedly more than 5 times, and then tighten the screws to resolve the problem. Automobile: According to the latest national standard in China, "Terms and Definitions of Motor Vehicles and Trailers," an automobile is defined as a non-track vehicle powered by an engine, with four or more wheels, mainly used for: transporting people and/or goods; towing vehicles that carry people and/or goods; or for special purposes.
