Over the past several months i have been getting everything that i needed to replace and improve the suspension on my 83zx. I got eibach springs, tokico struts, new tierods, new ball joints new bushings from motorsports. Two weeks ago i finally had time to install the final component, the bushings. That job ended up to be the worst part of everything that i did. The bushings that i got are meant to be installed in the control arms front and rear without the sleeves. I tried to press the sleeves out with a press but that did not work. I took it to a machine shop but they did not have any luck. What i ended up doing was using a hack saw and cutting the sleeve in two different places and then pounding them out with a screwdriver and hammer.
After all that work i was getting very pissed off. but after getting the new tires on and getting it aligned, i am extremely pleased with the results. The handling has improved 100%. and driving the car puts a smile on my face ever time i get take corners at speed.
Good luck to any one who wants to replace the bushings, the result is worth the work

The easiest way to get old rubber bushings out is to burn them with a torch. Keep heating until they start on fire, and let them burn a bit. Then all you have to do is push them out.:)
P.S. do this out side, lots of black smoke!

Actually, using a hydraulic press is far easier still! :^) I wouldn't heat critical suspension parts like that if I could avoid it.

The original poster is right about the shells, BTW. Using a hydraulic press to get those shells out is really iffy, unless you have just precisely the right drivers. I've heard of people using a zip gun and a cold chisel to scrape them out. I've also heard of people heating the outside of the bushing housing for a long time with a torch and then trying to push the shell out with a hammer and a socket. Of these, I've only tried the press method, and it proved impractical.

The correct way to do this ( for us mortals anyway ) is with a hacksaw. Very carefully, i.e.so you don't cut into the bushing housing, hacksaw a pair of parallel tracks about half an inch apart down the part of the shell which is best supported by the rest of the arm. You'll end up with a little strip of bushing shell that's barely held on to the rest of the shell, because you cut almost all of its connection to it. Now what you do is very carefully peel that strip away using a cold chisel of less than half an inch width ( adjust dimensions to taste, ) taking care not to gouge the housing walls. After this, the shell is just incrediby loose, and you can drive it out of the housing with gentle taps of a hammer on the right size socket.

A variant of this is also discussed in Wick's book, BTW. I think he uses it just to get the rubber bushings out, however ( hey, there's another idea! )

Just say, A hacksaw is a marvelous tool. Etc.

What brand bushings did you use and how did they come? Can you tell me more about the Tokico struts, you said in another message they they are very firm. What have you heard about the KYB's that makes you want to switch?

The tokico struts seem to be a little bit to stiff. going over bumps rattles the car quite a bit. I heard that the KYB struts were a little softer. not sure but that is what i heard.
The bushing the got were the ones out of motorsport catalog. ployurethane bushings.
