Loose Rear View Mirror

Any pointers on how to tighten the mirror? I popped the cover to access the base, but the adjustment bolt is not exposed. The arm for the mirror looks like one solid plastic covered piece.

This shows how it is attached

The ball end behind the mirror on mine is what's loose. The mirror stays in place, but just barely. Is replacing the mirror the only fix?

 

I saw that vid after i posted. If those two clips are all that binds it together with no real explanation on increasing the tension, I am not sure now if it's worth all that time to take it apart. Hoping someone has gone through the process

 

i hope not. the ball end on mine is still good, but the whole arm is what wiggles. i am guessing from all the years of offroading it just gave out. it's not a deal breaker but on uneven roads, it jiggles enough to look Blair Witch
