You can do it without removing the whole diff case assembly from the chassis. It might take a little more time, but you won’t have to mess with any of the steering linkages and stuff......

Start by removing the tires, bumper & body supports, sway bar and shocks. Then pull off the c-clips on the lower arms in the front. Next remove the lower metal pin holder by removing the two screws that go into the front of the diff case cover.

After that you remove the four screws that hold the diff case cover and remove it, you’ll have direct to the front diff.

Make sure you make a note of which side the diff ring gear is and where the shims are on the diff outdrives, that way it all goes together the way it came apart.

Put a little car wheel bearing grease on the ring gear when putting it together, so its not dry and button it all up together again.

You’ll have to play a little with the axels to get them in the diff cups when sliding the diff back into the case, but take your time and it’ll all go back together fine. Once you've done it a few times, you'll breeze thru it fast.
Good luck.
