How to Solve Rearview Mirror Vibration?
2 Answers
There are two solutions for rearview mirror vibration: 1. Center rearview mirror: Adjust the left and right positions so that the left edge of the mirror just cuts off your right ear in the reflection, and adjust the up and down positions to place the distant horizon at the center of the mirror. 2. Adjust the side rearview mirrors: For the left mirror, position the distant horizon at the center for up and down adjustment, and adjust the left and right positions so that the car body occupies one-quarter of the mirror. For the right mirror, when adjusting the up and down positions, ensure a larger ground area, about two-thirds of the mirror, and similarly adjust the left and right positions so that the car body occupies one-quarter of the area.
I've been driving for decades and have encountered rearview mirror vibrations quite a few times. Usually, this might stem from loose mounting screws. You can first check the interior rearview mirror bracket to see if the screws are tightened. If they're loose, just reinforcing them with a wrench can solve the issue. However, sometimes it's due to external factors, such as unbalanced tires or aging suspension systems causing whole-vehicle vibrations—in such cases, a four-wheel alignment to adjust the balance is necessary. If the rearview mirror is electric, wear and tear of internal components can also lead to vibrations, requiring professional repair. I recommend regular vehicle maintenance to prevent such issues. Vibrations not only blur your vision, affecting reversing safety, but also accelerate mirror damage, leading to higher costs. Before attempting any fixes, close the windows tightly to avoid misjudgment due to strong wind. Safety first—if you can handle it yourself, it's more convenient.
