I did this by hand on my car to save money
I was redoing the brakes so I jacked the car up, unhooked the brakes and pulled the beam.
I only had hand tools and a torch and it took me a few hours to get them out. A hand propane torch wasn't really hot enough to just burn them out so I had to do in stages. I ended using a hacksaw and a sawzall to cut the core from the rubber, then cut through the outer shell enough so that I could fold it over and then hammer it out.
Getting the new ones in, I had already purchased a big piece of allthread with bolts and metal plates from the rebarb section of my hardware store for cheap. I used these various pieces and some pipe fitting reducers for the front control arm bushings and the wheel bearings.
First off I got them lined up and then kind of used solid pieces of metal to spread the pressing action all over the complete piece, otherwise you could easily crank down and chunk that rubber off the new bushings. Once you get into it you kind of get a feeling for it. I used some duct tape to crudely keep my shims from flying all over the place.
I did bend my metal plates a bit but was surprised once everything started to bite that I didn't strip any nuts and I didn't have too much trouble cranking with a wrench. I found I had to readjust my angles with new shims a few times as you could see it wasn't pressing exactly straight.
As far as performance I have no history with these cars. When I loosened the back, the beam dropped to the ground so I know they were shot, I believe all original suspension at 200,000 miles so I replaced all that stuff.
