What common power tools are good for removing the metal sleeves that surround the urathane/rubbery material on the bushing?

I saw this video: But taking a hacksaw and chisel on the controls arms on the 21 mm bushing took me close to 2 hours each!! Mostly because a small lip forms at the end making it fasten into the arm.

Now all that are remaining are the 24 mm bushings sleeves that are connected to the subframe.

So before i waste another day on the other the other two does anyone have any recommendations on cheap POWER tools to remove them? I was thinking either a rotary file set, an angle grinder, or just getting some cutting discs for my cordless drill might do it.

On that note I'm still not sure the best way to press new ones in. I have a press in one of our labs that I was planning on using for the ones on the control arms but not entirely sure about the subframe ones. Without succumbing to a "J" tool, I was thinking about using a C clamp with two blocks of wood to press it in. What have you guys done?


PS before anyone mentions the obvious, yes I agree buying new control arms would've settled the first headache. The End.
