So I did search and read up on all the old posts... the clunk of the window was said to be the door strap, a piece that prevents the door from opening too much.I read what people have done, which is to grind off the T end inside the door. Well, I tried this and while inspecting, I was still unhappy with the result. The T end was awfully close to the window when I opened and closed the door. After looking at the door when u open it, I really think our door is just so weak that after time, the door itself is bending and NOT the door strap. So I bent the door sheet metal where the strap attaches and now when I open and close I have much more clearance from the glass itself. So I think grinding it will work. but if you want even more clearance, you can just bend the mounting sheet metal back to original position. Anyways, here are some pics.
