MY 06 leaks a little above the rear view mirror and compared to my 08, it takes very little effort to close the latch. I inspected the hook for wear and it looks fine. However, I did notice that of you put the latch in the locked position without the top being shut you can pull on the hook in an outwards position and it moves about 3/8 of an inch. I tried it on the 08 and it doesn't move at all. the one on the 06 feels as if there's a spring holding it back but again, not a very strong one. Is there an internal adjustment for it and is there actually a spring in there keeping it tight?
