if you have an old housing, cut it right next to the diff. Then weld two pieces of channel or tube to it so you can hang it in the press. Then bolt in the axle you want to dissassemble and press it apart. Dont forget to remove the snap ring first. I have done quite a few this way. The only thing I have had problems with is A 4 wheel ABS axle, I damaged the tone ring and had to replace it. I Think it would be wise to replace the bearings while you have it apart though. They dont las forever, and they are not that expensive. It could save you from having to do this all agains soon.
