Are you trying to take the hinge apart while it's still mounted to the body? If so, that's going to be really tough. I don't think you can even access the pin that way.
You'll need to remove the three bolts holding it to the pillar and pull it out.

If you're smart enough to take it apart, you darn well better be smart enough to put it back together.
