Are you sure that the leak is actually from the steering box? Most likely the rubber hoses have all gone bad or the seal or bearing in the steering pump has gone bad.

As far as removing the box it's a pain.. you need to disconnect the box from the coupling, remove the mounting bolts and disconnect the tie rod from the steering arm. BTW if you do remove the tie rod be sure to get the proper tool and leave the nut on otherwise you will ruin the thread and have to replace it.

What you should do is to first buy the replacement hose and then fill it up with fluid adn see where the fluid comes out and be sure that it isn't running done the hose from a leaky connection first before removing the steering box for an overhaul. It took me a day and a half to figure out how to get mine back in.
