You probably need to do what I had to do when I powder coated my old style Monster wheels. I had to use a jig saw to cut through the bushing (the outer metal portion) and then use a huge hammer and chisel to fold the bushing in. I took them to my local dealer to have them pulled and after 3 hours they could only destroy the bushings, not remove them. They did not charge me for the time spent attempting the removal. Once I cut them away and got the wheels back, it only took a second to mount the new bushings. I kept them in the freezer and with a little grease smeared around them, they popped right in.
