The diff comes out in two parts, the top (with bearing) and then the bottom.
Just don't let all the "innards" come out of the housing assembly, and you can lift it out, and position it on your bench upright.
Since you will need to remove the allen screws with the case turned on it's side, gravity will hold all the parts together inside the differential.
Here's the unit in the housing. You can see some of the old allens, and the new ones (note that they have all been upgraded now). The top cover and bearing come off, and slide out.
