Window squeaks over bumps when open

[BLUEBULLY]

2012 Hemi Express regular cab: I have noticed that my driver side window squeaks when going over bumps. This only occurs if my window is down. Has anyone else experienced this? If so, is there an easy fix? Has always happened even prior to lowering.

Mine doesn't squeak, but rattles...But I also have a 2004. Maybe same issue? I haven't taken apart the door to look to close yet though.

Mine rattles, has always done it. As far as I know all the 4th Gens. do it.

I know this is a old post but I thought I would ask. I noticed my drivers door /glass squeaks when lowering the window. And ideas on if it is a common issue? Something worn ... a Fix?
