Another method is to use a torch and "burn" the center bushing out, that makes a real mess and if you do it on the upcoming "carbon belch day", send a video of the process to owlgore and he'll send ya back double carbon debits.
Then I use a milwaukee "torch" blade inna sawzall to cut through the wall of the outer bushing, once it's split, it'll nearly jump out of the spring eye.
