What to Do When the Door Limiter Makes Noise?

[LaAngelina]

Here are the causes and solutions for abnormal noise from the door limiter: 1. Issues with design and manufacturing processes, causing noise between the limiter arm surface and the roller bracket side. Severe misalignment between the door hinge axis and the limiter rotation axis. Recommendation/Measure: The door hinge axis and the limiter rotation axis must be controlled to 's3', and the door hinge should be monitored. Solution: For problems related to design and manufacturing processes, seek replacement from a 4S shop. 2. Long-term violent opening or closing of the door, leading to deformation, bending, or damage of the door limiter due to force. Solution: If the door limiter is deformed or damaged due to force, it needs to be replaced. 3. Wear of the door limiter during use or door sagging. Solution: Replace the limiter if it is worn or its limiting function is reduced, depending on the situation. 4. Lack of lubrication on the limiter surface. Solution: The simplest method is to use lubricants like grease for lubrication and rust prevention, reducing mechanical part friction and wear, and extending fatigue life.
