My mirror have come a little loose and now when I go over bumps it makes a horrible noise. how do i fix?

 

Unfortunately, I don't have an answer for you... Here's the page from the Ford Service Manual that deals with removal and installation of the mirror.




I don't see any mention of an adjustment and/or tightening of the mirror. Is your truck under warranty?

 

Not any more, i see it loose where it mounts to the glass at the top. I just need to figure out how to fix it.
