It wasn't to hard to get them out. I used a 2" hole saw and a propane torch. The OEM bushings are bonded to the control arm so unless you have a very good press they can be a pain to get out. I drilled with the hole saw as much as I could then I took the arm outside and heated the outside of the cylinder. After you hear the rubber start to sizzle wack at it a few times with a hammer and the old bushing should come right out.

Use the torch to burn away any rubber left in the hole, and clean it up.
