This is specifically for doors, but my dad uses a generic HF hitch mounted cargo carrier on his JK.
It's a JK sport. I tried last summer to get them off and didn't have a jack or a pulley to help me, and my son-in-law is a big hulking 44 year old, with all the tools.If you get them off and don't have the new bushings just clean and grease up the old bushings and put the doors back on for the ride home. The bushings are a pot metal and corrode. That's why the hinges stick in the bushings.
JK or JKU?
