If the bearings are out and the outside bearing race is left still inside it....your probably going to need a dremel with a cutting disk. Cut the race as deep as you can from front to back (not into the swing arm housing....only the race itself...a little bit won't hurt) and then hit it with a punch and hammer....should break into pieces and come out. If it doesn't....cut a little more and try again.
Good luck and plan about two hours for that phase.
