Help getting flange off??!!

Spray the threads with some wd40 and let it set for awhile, then you should be able to tap it off from the backside of the yoke
Got it off with a steering wheel puller, just had to spend a buck on longer bolts. Worked perfect but now another issue.....I included pics that show what I assume to be the seal but it doesn't act like one. It has no rubber edges or middle rubber around the its center hole. It will easily push in and pull out a little and it spins freely around the pinion shaft if you put a little pressure on it and spin it. I can get a a small pick on the center but it won't budge. That can't be an outer bearing race and I'm completely missing the seal?? Could it? I just don't see how whatever this is is meant to come out. Help would be appreciated. Pics of the deal attached....
