I'm trying to get the rear wheel hub assembly off to replace the bearing. The passenger side assembly came off easily by hand... the driver's side is giving me trouble. I've already broken one gear puller (center rod stripped), and the new bigger one doesn't seem to be doing the job. Any ideas? I don't own a torch or anything to apply a lot of heat, so I can't really do that. I could cut the drive shaft in half and replace the entire shaft/hub assembly, but I can't even find anywhere that carries the shaft.
