"even a rock will crumble
if you smack it night and day"

Aerosmith


I have never had the pleasure of removing one of those steering arms but I would expect a lot of hitting, possibly at least an hours worth. An air hammer might help too. After an hour of smacking it and air hammering, I would probably try the air chisel and try to separate it. I had a balljoint once that I had to hit for about an hour. I said "See, if I would have quit pounding at half an hour I would have failed" That's when I start singin' Aerosmith and keep smackin' it.
