What Causes the Abnormal Noise When Folding the Rearview Mirror?

[MalachiLynn]

Abnormal noise when folding the rearview mirror is generally caused by insufficient lubrication of the torsion spring inside the mirror. You can disassemble the rearview mirror cover, spray lubricant on both ends of the spring, and then manually fold and unfold the mirror to see if the noise disappears. Repeat the process of spraying, folding, and unfolding multiple times until the noise is gone. Solutions for rearview mirror folding noise are as follows: 1. Method 1: Manually fold and unfold the rearview mirror, and clean all visible rotating components of the mirror in both folded and unfolded positions. 2. Method 2: After cleaning, wipe all parts clean with a fiber cloth. 3. Method 3: After wiping, spray WD-40 rust remover and lubricant on the rotating parts, applying it separately when folding and unfolding.
