What causes the abnormal noise when folding the rearview mirror of Boyue Pro?
2 Answers
Boyue Pro rearview mirror folding abnormal noise is generally caused by insufficient lubrication of the internal torsion spring in the rearview mirror. We can remove the rearview mirror cover, spray lubricant on both ends of the spring, and then manually fold and unfold the rearview mirror to see if the noise disappears. The process of spraying, folding, and unfolding can be repeated multiple times until the noise disappears. Solution: 1. Manually retract and extend the rearview mirror, and clean all visible rotating connected components of the rearview mirror during retraction and extension. 2. After cleaning, wipe it clean with a fiber towel. 3. After wiping, apply WD-40 rust preventive lubricant to the rotating parts, spraying separately during retraction and extension.
My Boyue Pro has been running for almost three years. Last winter, the side mirrors suddenly made a creaking noise when folding, like the sound of joint friction. I did some research and found that the folding mechanism needs lubrication, especially the bearings and springs at the connection points. I bought a can of spray lubricant and applied it a few times to the pivot points—the noise disappeared immediately. Since then, I’ve made it a habit to wipe the gaps around the mirrors during car washes to remove dust and prevent debris buildup, which can accelerate wear. Although the noise seems minor, it can indicate insufficient lubrication or part aging. Ignoring it might damage the folding system and affect daily use. Other Boyue Pro owners I know have shared similar experiences—simple maintenance can easily solve the issue, saving both money and hassle. Overall, the Boyue Pro has solid build quality, but these small details determine long-term ownership satisfaction. Don’t overlook them.
