Yep I checked that diagram in my manual and I thought it should be the seal I'm fighting but it just acts odd. Can I punch a flat head screwdriver between it and the casing walk without doing damage and causing a new seal to leak? I see no other way to get it out. I can gently get a small pick tool to grab it a bit by the pinion shaft but not enough to move it and I don't want to force it there and damage the shaft.
