i burnt mine out with torches. Sometimes they will come flying out apparently, although it has never happened to me. lol Once they start to get hot enough, it will build pressure and vent it out the side. Once it started to move, i gave them a tap with a hammer and they fell out. I did my a arms the same way
The low effort method is to use a propane torch or hotter, heat the metal sleeve until the rubber liquifies around the sleeve, then you can just tap them out or they will eventually slide out on their own. Hot, smoking, burning bushing can bounce anywhere, so work outside or in a well ventilated area and plan accordingly.
The high effort methods vary, but you either drill, cut, chop, or use a press to force the bushing out of the sleeve.
I use the propane torch method and prop the torch or position the sleeve so I can sit back, watch the smoke show, and wait for the bushing to pop out on its own.
Tried cutting, drilling , using a press, finally gave up and used the heat wrench. was trying to avoid the smoking, smelly Burning rubber.,, I don't know what's in there, but once it lit up, it was like there was pressurized propane in the rubber, it shot out a flame a foot long, for about 15 seconds ! (good thing I put them on concrete blocks and raked the ground where I was doing it.) That was "Interesting" to say the least !

I'm a little late but I've always burned them out - I set the cradle on some stands on it's side and place a 5 gallon bucket with a couple inches of water underneath - lite the rubber and let her go. When the flaming mass of rubber slips out, it's captured and extinguished - most of the "dripping mess" and soot ends up in the bucket too making clean up a lot easier - I use the same method when doing control arms as well.
OK, got the new urathane bushings. Gotta ask, WHY, on something that you " Don't want it to Move " at all, would you put grease on everything ?? I can understand it on Control arms, sway bars (they are supposed to move), But what is the" wisdom" of doing it on Cradle bushings ?? Thanks
Grease helps keeping water out. The shell and sleeve can rust if you don't grease a little. Polly to shell/sleeve isn't sealed and water could get into any voids.
Al parts can have same problem. Worse, Al parts in steel can have problems because of "dissimilar metal"/Galvanic/Electrolysis corrosion. Finish of Al parts might help or not, Depend on several factors. Even heavy Anodize finish can fail to protect when road salt is in the mix.
