How to Reinforce a Loose Ball Joint in the Interior Rearview Mirror?
2 Answers
If the ball joint of the interior rearview mirror is loose, you can tighten the screws with tools. Generally, the loosening of the interior rearview mirror is caused by the hanging of a dashcam or heavy decorations. Therefore, it is recommended not to install the dashcam entirely on the rearview mirror connecting rod, and it is also not advisable to hang heavy decorations on the rearview mirror. Below are the adjustment methods for car rearview mirrors: 1. Adjustment method for exterior rearview mirrors: Adjust the seat position so that the seat height allows a clear view of the front edge of the engine hood. Adjust the rearview mirror vertically so that the sky and ground each occupy half of the mirror, with the ground slightly more. Adjust the rearview mirror horizontally so that the inner edge of the mirror captures the front door handle of the car body. 2. Adjustment method for the interior rearview mirror: Adjust the seat to a comfortable position, align the horizon to the center of the rearview mirror, and ensure a full view of the rear windshield.
When I first bought my car, I also encountered the issue of a loose ball joint on the interior rearview mirror. It wobbled so much that I couldn't clearly see the traffic behind me, making driving quite nerve-wracking. Later, I discovered that its design is actually quite simple—there's usually a small screw or snap-fit structure at the base of the ball joint. Just find an appropriate small wrench or screwdriver and gently tighten it, applying moderate force to avoid breaking the part. If the screw is noticeably worn, you can temporarily reinforce it by inserting thin shims, such as metal washers or soft plastic pieces, to secure it in place. After adjusting, test the mirror's angle to ensure it's stable and doesn't obstruct your view. Safe driving relies heavily on this rearview mirror, so don't delay fixing it. If you can't handle it yourself, quickly drive to a nearby repair shop and have a technician check if the base is loose—they'll professionally resolve it in no time. Make it a habit to inspect such small components every six months to prevent potential risks from escalating faults.
