The easiest way to take them off the vehicle is to jack it up from the frame until the load is completely taken off the shocks. Then unbolt them from the vehicle. The top of the coilover should have an adjusting nut that needs to be loosened to remove the pre-load on the springs. With the pre-load removed, the coils slide up enough for the bottom cup to lift up off the bottom of the shock and slide off the shaft. drop the springs off the bottom and replace the one you want to and reverse the removal process. :thumb:
