Mirror Vibration

[JohnnyR]

The right towing mirror on my 2012 3500HD DRW vibrates slightly whether extended out or not. Driver's side mirror is steady as a rock. Is there a way to tighten the glass in mirror oir is there another solution? Thx in advance for any advice.

I don't know if the glass can be tightened. It's mounted in a ball/socket. The assembly can be tightened, though. Remove the "shark fin" cover on the inside. The nuts that secure the assembly are behind it.

If the housing isn't vibrating, but the mirror is, the problem is a loose mechanism that positions the mirror. Is the truck still under the 3/36 bumper-bumper warranty?
