Too much beer in there! LOL!
Seriously - I wonder if there is a missing bushing. Like Mike837go said, there is usually a nylon bushing (spacer) on top of the bottom hinge and beneath the top hinge. If you are in an emergency situation, you could always take the top one and put it in the bottom, which gets more stress due to weight.
