Removal & Installation of Houdaille Shock

[philipswanson]

I am working on a 40 wagon and tying to pull the L/H axle housing. I got everything undone except for the Houdaille shock. I am looking for the best way to remove it without beating it to death because I would like to have it rebuilt before assembly. Anybody know the best way to remove it without beating it to death? All seems rusted in place. Doubt if it was ever pulled before since new.

Thanks, Phil Swanson
