The local parts store also has Haynes and Chilton books.
Anyway, like I posted earlier, jack up the rear of your Bronco, since it's centered, I usually go with a floor jack under the pumpkin and a jack stand about half way out the axle, so have room to work with the brakes. So pull the tire off. Then look on the back side of the drum...there should be about a 1" long slot centered on the bottom half of the rear of the drum. This slot will be just big enough for a flat blade screw driver or the special tool (looks kinda like a mini crow bar). On the other side of that slot will be a star wheel...you want to rotate that (can't remember up or down) so the shoes will release a little bit. You need the shoes to relase because, like it or not, grooves form on the drum or pad and they inter-lock. So once you back the shoe off enough, you should be able to just slide the hub off.
I don't have a floor jack nor a jackstand.
