I couldn't get the entire pinion seal out with a seal puller so I drilled a small hole in the top of the metal face in the seal and screwed an aggressive metal screw 3/4 of the way in. Then I used a prybar, pulling down on the screw, prying against the face of the diff housing. The whole seal came out very easily and quickly.
