That's the one I thought you were talking about. Here's what I suggested a few posts back...
Drill a small hole in that seal and thread a drywall screw into it to either grab with a pair o' vise-grips or to use as a means to get the seal cock-eyed enough to get underneath it with something else. Could also knock one side of it inward with a punch or screwdriver to at least get it loose and maybe crooked enough to just pry out. (Pretty much what Vinny suggested.)
And a bearing separator is exactly like a big hammer and a deep well socket -- except in reverse. It separates bearings and gears from shafts by sliding under them when a traditional puller can't fit. In most cases the bearing can be reused if not already damaged. A short vid showing how one works
