Thanks for nipping that in the bud, Jack.
Buttercup, the easiest way I found, short of putting the entire trailer on an overhead lift, is to replace one axle at a time, by pulling the front axle on blocks, or ramps, until the rear tires are off the ground. Replace the axle, tires, brakes, shocks, etc., whatever you are going to replace, then roll back off the blocks, or ramps, and pull up with the new axle on them, again until the tires of the old axle are off the ground, and repeat the process. Then, celebrate by applying ice to your smashed knuckles.
