this is a little diffrent procedure than on a regular pickup f250 is a three quarter ton. has the large brake drum with the axel running through it and bolted to it. the row of bolts on the center. of the part that sticks trough the rim are axel bolts they have to come off. the axel out. once axel is out you will be in to wheel bearing it hac a big lock tap on it remove it then remove weel bearings. then use your big hammer to remove drum. in essence once axel is out rear drum comes off pretty much like a front drum.
