My drivers side mirror is slighting shaking when driving and when you touch the mirror itself it does seem to be a bit loose.

Anyway for this to be fixed?

 

not sure about stangs but on my dads car i was ajusting the mirror and it fell off and broke about a year ago. On the car there was like a cross and on the back of the glass mirror was a clip that connected to the cross to be moved and stuff so maybe you can pop it off then pop it back in bettor or maybe part of the clip broke like on my dads mirror. Ita was like 70 bucks for a new piece of glass

 

my car does that when i crank up the bass. love that mach460 sound system

 

They wear out inside, aftermarket ones are pretty inexpensive, I put a new one on my son's Focus (cable adjust) for $29. Ask and price around. Our '94 V-6 had shaky mirrors too, common Ford problem when they get older.
