How to Reinforce a Shaking Rearview Mirror?

Adjust the left and right positions to align the left edge of the mirror. For the upper and lower positions of the left rearview mirror, position the distant horizon in the center.

When I first drove this old car, the rearview mirror would shake violently over bumps, causing blurred vision and distraction while driving. Upon inspection, I found it was due to loose mounting screws. A simple method is to first pinch the mirror base with your hand to check for obvious wobbling; then use a wrench or screwdriver to tighten the screw located at the connection point between the mirror and windshield. If it still shakes after tightening, the internal spring washers might be worn out. You can add small washers or rubber rings for reinforcement—I once cut a piece from a bicycle inner tube and it worked perfectly. Remember to handle gently to avoid damaging the car. A shaky mirror isn’t just annoying but could also lead to accidents. I recommend checking these details every time you wash your car to ensure safe driving.
