when i put my leveling springs in, i put one side of the frame up on a tall stand with the jack under the axle half, disconnected the coil retainers, shock, and swaybar, dropped the jack down, and then stood on the hub. the old spring pretty much fell out. the new spring was tight, but i didn't need compressors.
maybe put a bottle jack between axle half and the framerail to force the axle down more.
