You have to pull the shafts first.

Open the cover

Pull the pin that holds the pinion shaft-insert the ARB tool that looks like an allen wrench with threads and pull out the inner part of the pin.

Rotate the assembly slightly and line up the pinion shaft so it slides out toward you.

Carefully slide it out and catch the inner retainer block/ring

Push 1 axle shaft in and carefully remove the c-clip (don't drop it in or you have to fish it out later)

Do the same on the other side

Pull the axle shafts all the way out

At this point I would re-assemble the diff hand tight just so you don't loose any of the bits or forget how they go in. (I lost the heavy ring that goes with the retainer block once)

Now you are ready to pull the differential.
