When I put my ES bushing in, we did it with a small press I have at the machine shop I work at. It's basically a bottle jack (don't know how big, sorry) upsidedown with 2 steel bars going across. To do the front, we used a couple of bolts to push the center rubber bushing/sleeve out and then clamped the LCA in a vice and put a hacksaw blade through it, reattached the hacksaw and then just cut the outer metal sleeve (be careful not to cut into the LCA itself). Once it's cut, you can hammer on it with a flat screwdriver and it will come out (the pressure is released once it's cut). For the rears, we took a piece of round brass stock and put it in a lathe and machined it down to exactly the same dimensions as the outer metal bushing and just pushed the SOB out that way. Worked pretty well (sounded horrible but the brass is soft so it took the brunt of the damage) but you need an accurate lathe and a piece of brass stock, so I don't know if that's the best option for most people (the hacksaw would have worked for the rear too, this way was faster). To push the new bushing in, just soak those sucker in grease and you can push them in with a vice. That parts easy.
