Do you need to remove the outer bearing race to change this seal or only the axle shaft?

What is the best way to pull these. Do you have a special tool for pulling and then putting the new ones back in.
Willys Tech:
We usually just use a needle nose screw driver to get the old one out. You want to tap the new one in evenly and seat it.

I recently purchased 2 inner seals from you for my dana 44 on a 67 cj5. When I removed the differential there were no seals. Does this axle require inner seals inside the case? I didnt have issues with an oil leak. I was doing this as part of a restoration. I'm not sure why these seals are missing if they were required. I've had this jeep since the early 70s and dont recall work being done to the axle.
