Due to the constant tweaking and turning they’re subjected to, they can easily become loose. This article will show you simple ways to repair your driving mirrors whenever they are loose.

How To Repair a Loose Rear View Mirror Ball Joint?

To repair a loose rear-view mirror ball joint, look for a screw under the mirror close to its flip tab. Once you locate it, use a screwdriver to drive the screw back into place and tighten it. This should do the trick.
However, if the ball-joint connection of your rear view mirror is found on the roof, then it’ll be pointless to look for it underneath the mirror. Follow these next steps to fix the loose rear view mirror:

1. Remove the Plastic Covering Around the Mirror

Rearview mirrors come in different makes, thus there’s no one-size-fits-all approach to removing the plastic covering. Consult the car’s manual for directions on how to take off the plastic cover around the mirror to get access to its base. Remember to exercise caution in removing the plastic covering so you don’t end up damaging it.

2. Tighten the Ball-Joint

Taking off the covers of the mirror will expose the base of the mirror where you’ll find the screw which will adjust the mirror. Find the right screwdriver and drive the screw clockwise until it is firmly in place, and that will be all. However, other vehicles may not have the screw under the mirror or on the roof, but inside it.

You can look up how to find the mirror’s ball-joint location in your car’s manual, which will require that you disassemble the mirror. Carefully remove the mirror and secure the ball joint firmly.

Here’s a detailed guide on how to do it:

1. Remove the Old Glass

If the old mirror glass is still in the mount, then you’ll have to remove it to add the new one. This is especially dangerous if the old mirror is broken with some remnants still stuck inside. We suggest that you use thicker gloves for this step to protect your fingers.

The next step is to clean the mirror mount of all dirt or grime that may have gathered. This is necessary to keep the new mirror firmly placed. You can use ethanol or IPA to clean the outside of the mirror mount and the new mirror as well.
