Thanks! Just needed to know I wasn't missing something...
I picked up this set this morning:

The big one worked great on the axle ends. A couple hits with a hammer, and the seals popped right out. I tried using the small one on the pinion, but it was too flexible--the hammer just bounced off it. Luckily, I was just able to get the tip of the big one in between the pinion shaft threads and the seal, and then a couple hits and that seal popped out, too.
There's no seal in the axle tube ends on the front, is there?
