Like any normal bonded bushing or is this above and beyond that for some reason?
I just removed the ones from my RC lower control arms and it was a little time consuming but not bad once I figured out what to do. Basically just pressed the inner sleeve out of the rubber, then pressed the rubber out of the outer sleeve, cut the outer sleeve with a saw, and then chiseled it out of the arm.
I had that adventure on my 280Z, did ALL the bushings in the suspension, when I was 18, so I remembered the general idea of what I was in for.
