Reasons for Squeaking When Folding Rearview Mirrors?
2 Answers
Folding rearview mirrors may squeak due to lack of lubrication. Here are the solutions: 1. Clean certain parts: Remove the rearview mirror, clean the rotating parts, dry them with compressed air, and then apply lubricating grease. When the rearview mirror is folded, the squeaking sound is caused by abnormal friction from dust or sand particles entering the rotating parts. The solution is to remove the rearview mirror and clear the foreign objects. 2. Fold when unnecessary: The folding function of rearview mirrors refers to the ability of the side mirrors on both sides of the car to fold and retract when necessary, which can be manual or electric. During driving, accidents are inevitable. As the widest component installed on the vehicle, rearview mirrors are most susceptible to impact in case of a side scrape. To minimize scratches, rearview mirrors need to have a folding function. Rearview mirrors with a folding function can be retracted when passing through narrow sections, improving the vehicle's passability. When the driver leaves the car, the rearview mirrors can also be folded, not only protecting the mirror surface but also reducing parking space, effectively avoiding scratches.
I've been driving for over a decade, and when the rearview mirror folds with a creaking sound, it's mainly due to lack of lubrication or dust accumulation in the internal components. For instance, during dusty spring and autumn seasons or humid rainy days, debris can build up in the moving parts, increasing friction. Worn-out springs or gears can also cause this. If not addressed promptly, it may become increasingly stuck, and for electric folding models, it could even burn out the motor, leading to costly repairs. I once encountered this issue while driving on the highway—the noise was so annoying. Later, I used a small brush to clean the dust and sprayed specialized lubricant, which significantly improved the situation. Regular maintenance should avoid using water to rinse the folding joints to prevent this. If the noise is severe, it's best to visit a repair shop for a thorough inspection. Don't delay too long, as it could affect your daily visibility and become troublesome.
