Get a Haynes manual or a similar manual, lower the spare tire on the four door model, if yours has the spare under the rear. Make sure you used as much fuel as you could. Put a big piece of wood on a jack and put it under the tank. Make sure the wood doesn't cover the straps though. Disconnect the filler hose and fuel lines in the back and the vent lines in the front. disconnect the wire harness. Unbolt the rock guard on the left hand side by the rear wheel, and unbolt the straps and lower it. That's about it. The manuals will have pictures, and if you can't afford to buy one you can probably pick one up at the library. (Our Columbus library has several.) They really help.
