Cheap tubular control arms for replacements?

When they're rusty like that and don't want to come out with my bushing puller I cut across them with the Sawzall right where that rubber is bulging. The inner sleeve and rubber can come out at that point. That's when you cut a slot along the inner length of the outer sleeve(careful, not so far you actually cut into the control arm) and pry one edge over the other as Crackedback recommends.
