I have a 2006 sport X, its used and I recently tried to take the doors off for the first time and they wouldn't budge. I think the hinge is seized up to the bushing. What I think I need to do its take the hinge off and use heat to get it apart. I would rather not do that so if anyone has any ideas for some help please post back.
Just soak the hinges good for a few days with PB Blaster, roll down the window, open the door and walk back and forth while lifting up on the door. It seems to have a sweet spot at about 3/4 ways open. It comes out real slow but when it comes off, make sure you have a good grip on the thing so it doesn't go flying. Then sand the pins with some fine sandpaper and coat them with white lithium grease. Some people use a jack to lift up on the door but I think that's nuts.
