2006 Edge touring

torsion springs or coil over springs? Coilover springs you just undo the top bolt on the shock, might have to lift the rear to get some weight off the shock. Once the top bolt is take out just lean the shock forward and remove the spring cap, and the spring will slide right off. Replace with the new one and re install. Torsion springs are a little bit trickier. I used a piece of square stock with a slot cut in it, and a T handle welded to the other end to twist the torsion spring to take the load off of it while a buddy installs it.
Good luck,
Nolan
