The answer is bushing remover. More on that in a bit.
You can see from the pic that it is good I am replacing the bushings. Very worn.
I first tackled the front of the torsion tube carrier. This was simple. Cut off the rubber "ring", then get something metal that is the size of the inner metal portion of the OE bushing and whack away. Out in minutes.
Getting the old rubber off the spring plate bushings was just as miserable as everything I read said it would be. Razor blade. Wire wheel. Lots of rubber dust.
End result of the weekend. Exhaustion.
