You are not going to believe this but, I had a bunch of swollen wear rings and wanted the aluminum (cause I was getting ready to make a recycle run and get a few $$$ for the junk aluminum). I had to get creative on getting the steel sleeves out. Tried a hammer, throwing it down on the ground, etc. Nothing was working. Being creative, I looked around the garage a bit and came across my hydraulic jack. Ok, now I had to figure out what to wedge it up against. I kept looking around and when I got to my Land Rover the friggin light bulb went off. There was enough clearance to put the jack underneath the land rover and fit the wear ring between the jack and the frame of the rover. I started cranking the jack and about the ninth pump there was a nice cracking sound. Looked underneath and voila, the wearing aluminum housing was in four pieces. I had several more to do so I got my nephew and daughter involved. We took turns cranking and we guessed how many cranks it would take.......good cheap fun!
