I have posted the following previously, but it seems this needs to be brought up again:
--------------------------------------------------------------------------
"By the way, for all of you that have "shakey" mirrors, this too is a simple fix, for which Ford was going to fix for $440/each (mirror replacement).
Basically, the mirror is held in with one large center mounted plastic snap pin, guided by two opposing corner slide pins, and operated again by two opposing corner actuators.
I found that my slide pin guides were loose, being a simple thin metal clip, and the actuators were loose where they are snapped into place on the mirror mount.
1) Pull mirrors per web site (Muth) instructions - simple
2) I simply crimped the metal slide guides in a little more so that they were tighter on the slide pins.
3) (Don't laugh) I stuffed a little aluminum foil around the base of the actuators using a small screw driver.
Viola...no more shakey mirrors. All it took was about 1/2 hour per mirror, which if I used Ford's labor rate, would mean that I should be charging folks about $900/hr to do provide this fix...any takers?"
I hope this helps.
