So my G35 has recently developed this extremely annoying issue involving the passenger-side window. It rattles when people slam the door shut and when I drive over rough surfaces, and the window slams down with a loud "THUNK" when the window is rolled all the way down. Any idea as to what is causing this and how to fix it? I was told by a friend its most like the window track/rail.

TIA.

Thanks for the link. Can't believe the fix is as easy as removing a door panel and tightening two bolts!

 

mine started doing it to after my window tint
