Why Does the Door Check Strap Make Noise?

[SanNoah]

There are several reasons why a door check strap may produce abnormal noises, such as: 1. Lack of lubrication: Insufficient lubrication can cause friction between the check strap and other components, leading to noise; 2. Deformation of the check strap: Improper use by the owner or involvement in a car accident may cause the check strap to deform; 3. Improper installation: Some vehicles may have quality control issues from the factory, where technical reasons might result in the check strap not being installed in the correct position, causing noise. The door check strap is designed to limit the movement of the door. When force is applied to the door, it restricts the door's rotation to prevent it from opening automatically. Check straps are mainly divided into two types: spring-type check straps and torsion-spring-type check straps.
