drop the subframe as low as it will go and sawzall (reciprocating saw) through from the inside out though the metal part of the bushing, you know when you are through when it pinches the blade (go further and you are sawing on the subframe), put a couple sockets on top of the bushing and jack up the subframe pushing the bushing out, soap up the new bushing brace the subframe against the floor and jack the bushing inplace
