That is not easy, and you don't get them out in 1 piece.
The best way is to burn the rubber out and after that hack the bush to pieces with a hammer and a big screwdriver or something sharp.

If you have one of the bushings where there is a hole all the way through the rubber, I would take the blade off a hacksaw, stick it through the hole, mount it on the hacksaw again and then cut through the rubber and CAREFULY through the outher steel ring from the inside. Once you are through that it should be easy to push the bushing out, because it would shrink in diameter due to the cut.

I find that the centre metal bush comes out fairly easily.  You can then cut through the rubber and the outer bush with a hacksaw or an air hacksaw with care.  Once you've sawn through the outer sleeve it will just tap out.

ok. so they will be destroyed.
if I got a tool with 32cm wide it should be possible to press it out without destroy it? 
and the follow up: how do you press it in?  ive found some shafts meassuring 32cm wide.

Length of threaded rod and two large sockets - one large enough for the bush to fit inside and the other the same diameter as the outer sleeve.

If it is on the car for 25 years, forget pressing it out.
We couldn't get it out with a proffesional  press no matter how hard we tried.
Pressing it in is fairly easy with some grease and a press.

In order to have any chance of pressing the bushing out, you must have a block for the housing to rest on, with a hole only slightly bigger than the bushing. On top, the piston must of course be slightly smaller than the bushing, but still ride solidly on the outer bushing ring.

Then, as you apply pressure, you must heat the housing, probably with a gas torch. Just don't melt the housing, or catch the rubber on fire. Wink

As the housing heats up it will expand and loosen its grip on the bushing, but only until the bushing also gets hot. So pressure, then heat, cool down and repeat.  Grin

Good luck. (you will need it) Grin Grin Grin
