Try this old JU thread -- helped me do mine. http://www.jeepsunlimited.com/forums...t=hinge+ pins
It's probably just bad bushings in the lower hinge (you need 2 per hinge), but you will need a new pin.
Edit: it has been quite a while since I did mine, and it's still good, but I have to scratch my head to recall details. I did not need to unbolt the hinge. It's a bit tight, but not too difficult. I used a small 'ball' type grinding stone in my drill instead of a Dremel. If you have any questions, I will do my best to help!
