Wow this is hard, I just figured out one problem, behind the bottom hinge there is a pocket. When I got my trwuk, is was rooted(like TX cars never rust) Anyway, I replaced it, what I noticed was wear spots on the hinge from the freshly primed surface of the hinge, so, slipped my hand down there and could feel the hinge striking the pocket.
Lets see what other things I find, I have to fix that, did not see that one coming.
