Notice that the hinge pin is pressed in on both sides of the hinge.
This can only mean one thing: we get to do some good ol' metal cutting! I would start on the bottom first, so the top can hold the door's weight.
I used my handy-dandy dremel tool that I got at Ace Hardware for $40! Such a good deal!
Now, each pin should take a full grinding wheel or two, that is normal.
Now cut into the middle of the hinge pin, which will result in this
We still have to get these pressed pins out, and to do this, I used my good old prybar as a lever to get each side out
They might take some creativity and some gumption, so be patient.
Repeat the last step for the top hinge
Probably needless to say, but I'll say it anyway.
Nothing is holding the door on now, so we can just pull the door back, and off the hinges.
If your wires aren't out of the interior yet, you will wish they were
And the end product for one side
What about being legal without doors?
In most areas, the law requires two mirrors, so you will have to find a way to get a mirror on one side (in most states, the driver's side) of the Jeep. I got a Autozone mirror and ghetto-rigged it to sit on the hinge. Simple, but functional.
I sprayed some duplicolor engine enamel on it, to get rid of the chrome, and it was good to go.
What about putting them back on?
Well, if you are like me, you now want them to go back on at some point
So how are we going to do that? Quick pins come to the rescue here
I got two different types: cotter pins and quick pins
Both have their strong points, but I find cotter pins easier to put in at the top, because they are offset at the bottom, and won't be a pain to install
Quick pins, on the other hand, have a ball-lock, and are good for security, as the cotter pins technically can rattle out (though I think it's a long shot of them doing it)
The rest of the re-installation is pretty intuitive
Just take the kick panel off again, feed the plugs through, plug them in, and you're set.
This isn't like installing a lift, rotating your tires, or changing your spark plugs. This is a modification that has certain ramifications:
1. You will never have stock hinges again without buying full stock ones from MOPAR
2. You will probably never have it seal perfectly anymore, as the pins you use will not fit perfectly, because if they did, you wouldn't be able to get them out again. Thus, the door will hang down a good 1/8 or 1/4".
3. You will always need a set of hands to put the doors back on, as lining it up is nearly impossible without them. And note that people will not always want to go out at 11:00pm to help you put your doors back on.
4. You will never want to drive with doors again, and it will become an addiction.
5. Be prepared for everyone's stares at the doorless cherokee.
6. It is illegal in some areas to drive doorless, and it is illegal in MOST areas to drive doorless without mirrors. Conduct yourself accordingly.
If you are okay with this, then doorless it is. If not, wait till you have a little more experience and help, and you can be doorless too.
Have fun, be safe, be legal, and drive happy
