I'd love any insights from anybody who has taken apart the door mirror before.

In the picture below, the colored portion of the mirror is loose and making a rattle whenever I close the door. It its noticeably looser than the other side.

The question is this. Is there some sort of a fastener that secures the colored section of the door mirror to the assembly? Or is it a snap on affair, and the fact that it is loose means something has broke?

Its been this was as long as I have had the car.

 

The rattle fix thread has posts related to this problem. I had the same issue and posted my solution: https://www.rx8club.com/rx-8-discuss...0/#post4399133

 

That thread describes it perfectly! I just wonder how it got into that state in the first place.
