I figure that because I've done it myself with normal hand tools.
What you do is:
remove diff cover, draining the gear oil
remove the cross pin retaining bolt, then the cross pin
push the axles inward, and remove the c-clips, then pull the axles out some
now it would be easiest to remove the bearing caps and pull the diff assembly out to do the rest on a bench (be sure to note where the shims are located and the orientation of the bearing caps (arrows face out I believe, and the left and right need to be put back in the same place)
now with the diff on the bench, carefully remove the "s-spring" that is forcing the side spider gears apart
you can now get the spider gears out and then replace the clutches and steels
For a little extra grip you can change the order of the new clutches and steels that you put back in. I did it in mine and it seemed to help. I put them in clutch, steel, clutch, steel,clutch, etc. You'll have to re-use one of your old clutches on both sides if you do it this way, btw.
Now assebly is just the reverse order. The only difficult part is getting the s-spring back in. Some people say that you can whack it with a large hammer (BFH) and it will go in, but i couldnt get that to work on my car, so I compressed it as best as i could with a strong hose-clamp and then installed it. I then cut the clamp and removed it with a pair of pliers.
Unless you call a big ******* hammer and a hose clamp special tools, then I don't see the need for any
hope this helps
