Nothing hidden. Support the rear axle AND the frame. Remove the shock absorbers, the front spring pivot bolt, the carriage bolt at the rear shackles and pry the plates off the pins (tapered) - you might need to remove the zerks if the plates don't come off easily. If you disconnect the driveshaft, and have the wheels on it, with the frame high enough you can roll the whole rear axle out from under the truck (you'll need to disconnect the brake line between the frame and the axle on the right side.) There are 4 nuts on the u-bolts on each side to remove the springs from the axle. Here's a diagram from the Factory Assembly Manual with the fasteners highlighted you'll need to remove.
