Hey guys, I have a 2004 4Runner V8 Sport edition, and the front door windows rattle when I shut the door. I am making sure they are fully up, but they still seem to move. (I can push on the window from the outside and they almost move in about an 1/8" at the bottom) The back windows are nice and tight, and the doors sound really solid when I close them. But the front ones not so much. Does anybody else have this problem? Is it typical of a 4th gen 4Runner? Anything I can possibly tighten or look at or would I have to pull the door panels to investigate. It drives me nuts because every time I shut the drivers or passenger door it sounds sooo cheap !!
