Door Hinge Pin
As trucks get older the doors begin to get hard to close. Often times the hinge pins are simply worn out. There not that hard to replace. The kit is pretty cheap and there is a tool that doesn't cost much either. You can try to get the spring back in place without the tool, but after you work on it for an hour you'll wish you had the too.
