First picture is of the differential that I am working on. Second picture is a example picture showing driving the pins out. I’m trying to get mine apart, but there are no two holes to put a punch into, to drive the pins out? Is there a tool made to work on the other side for extracting the pins?

Probably time to drill the holes yourself. I doubt that case is hardened, but use carbide drill bits if it is. I can envision (and could make) a tool to clamp around the pin and hammer on, but drilling the holes would be much faster and easier.

Might not be so easy to drill holes in the right place. It’s right about where a couple strengthening ribs are. May have to come up with an idea to press the “bearings” out at the ends of these shafts. They seemed to be pressed in with some interference fit-tight! 0875C72C-7305-4251-871D-884EA29DF56D.jpeg

I can only see the pics provided, but I would consider putting an open end wrench over the shaft and then use a long punch through the ring gear hole (and hit the wrench "down low") to try to knock the "bearings" out.

If that's the Eaton here's the exploded view if that helps.
BTW I have the rebuild info if you need it. If it's one of the other rear ends I will have it as well.
