Slowy, I've not personally dismantled one of these either however I can impart some relevant experience.

On some diff setups, the splined axle end has a retaining where it passes through the sun gears within the diff centre (item 23 on the exploded diagram in Zedn's post). However I can't see one on this diagram, so I suggest it is just tight on the bearing to housing surface and what ever gasket cement has been used of the flange.

This simply means prising it out with a lever, as it appears there are no jacking bolt holes to use. Firstly with something sharp like a wood chisel, gently drive it between the carrier flange and the diff housing to break the gasket seal. Maybe start at a spot where there is a casting gap between the flange and diff. once you've moved this a bit get a prybar or tyre lever in the gap and work it out.

If you work you're way around the flange with the chisel, it should eliminate the risk of cracking. Be sure though to clean up any burrs this creates.
