I thought I learned how to do this from the Bentley Manual...  Here's what I do:  Unhook the rear sway bar from the rear swing arms.  Disconnect the 3 rear most muffler hangers so that the muffler drops several inches.  Using a small hydraulic jack lift up slightly on the rear differential and remove the mounting bolt.  Lift only enough to remove the pressure from the bolt.  Then gently lower the differential several inches.  You should now be able to drop the rear swing arm enough to remove the springs without hurting the CV joints.  You might want to use the hydraulic jack when lowering the rear swing arm,  that way it doesn't just drop when you remove the lower shock mounts.  Good luck.
