It has been said here already, but having tall enough jack stands is very important. You will not get the axles low enough to pull the springs. To get the springs back in after the spacers are installed on the front, I used a prybar through the bottom of the spring and the top of the base that the spring goes around on the axle. If that makes any sense. That was just my experience anyway. Did this alone front and back in probably 4 hrs with a few frustrating moments, lol.
