How to Repair a Broken Folding Mirror Gear?

[Ronnie]

If the rearview mirror gear is misaligned, it cannot be repaired and requires replacement of a new folding gear set at a 4S shop. This method involves manually adjusting the position of the mirror frame or surface while the vehicle is parked to achieve the desired viewing angle. This method allows the driver to adjust the rearview mirror while driving, providing a more convenient way to observe the rear view.

Last time the gear in my folding side mirror broke, causing the entire mirror housing to jam and become immovable. I took it apart myself to investigate and found severe wear on the small gear, likely due to metal fatigue from years of folding. Having the tools on hand, I tried cleaning and lubricating it, but with little effect, so I ended up buying a new gear set to replace it. This incident reminded me: regular maintenance is crucial—spray some lubricant every few months to prevent jamming. Gear matching must be precise; using the wrong model can accelerate wear. Avoid forcing the mirror to fold, as it can strain other components. If you can't fix it yourself, it's better to spend some money at a professional shop to avoid bigger issues that could compromise driving safety. Remember to check regularly—it saves both money and hassle.
