You need a 1 9/16 deep impact socket and a 3/4" air impact. Securely mount the shock and run it. On shocks that are not rusty the impact will get it apart. A few may need the outside heat cycled to about 300 degrees a couple of times. Then it hit it with the impact.

Kind of a real short answer. I need to do a better write up at some point. There are a lot of little details that get you a good finished shock.
