But understand if you put jack stands under the axle the rear shackles are still under load. You need to unload the rear springs enough but not to much and it will be easy. Place the stands under the front perch area with 2-4 inches of tires above the ground first. Then with The jack under the center of the axle you can raise and lower it as needed to facilitate the swap. Fortunately the rear bushings are slip in.
