I made the DIY puller described in the wiki, and even better with a .25" thick aluminum washer that I cut to size that is just a little smaller than the bushing, with .25" center hole for the threaded rod. I have a 1/2" socket that fits perfectly to the outside frame flange with enough clearance for the bushing to go into. I cant get the bushing to budge. I put some light oil around the bushing and pulled from the inside outward. Is there a better way?
