Dropping the front diff is not easy, but it is mostly straightforward. Here's how I do it:
Make sure the fill plug on the front of the diff can be removed and isn't frozen, then drain the gear fluid from the diff. If you don't plan on removing the stub shafts you don't HAVE to do this, but that thing is heavy enough to wrestle around, it's worth $20 in gear oil to me to not have that oil sloshing around inside.
If you have a vacuum actuated diff, remove all the vacuum lines.
Unbolt the CV axles from the stub shafts.
Unbolt the upper ball joint on both sides.
Loosen the bolts on the driveshaft, but leave them finger-tight.
Unbolt the front crossmember from the a-arm towers left and right (you can also just unbolt the diff from the crossmember, I think dropping the whole thing makes it easier to get back in).
Place a floor jack underneath the drain port.
Move the steering spindles outboard (which you can do because you unbolted the upper ball joints) to give the CVs room to slip off the studs on the axle stubs.
Begin backing out the two vertical bolts on either side of the diff that secure it to the chassis mounts.
You'll probably need to tap/gently pry on the crossmember to get it to drop out as you back out the vertical bolts. Do each bolt about an inch at a time and lower the diff to the floor jack. Once the bolts are out and the crossmember free, the diff will want to drop so have the jack in place and supporting it before then. Another pair of hands here is great to keep the diff from rolling off the jack, because all that's attached now is the drive shaft.
Once the diff is down, detach the driveshaft, and you're done. Installation is basically the reverse - I bolt up the driveshaft first, raise the diff, coax the crossmember into place while installing the vertical bolts to the chassis mounts, and finally reattach the CVs to the stub shafts.
Now would be a great time to pull the stub shafts out of the diff and pound those studs out. Take the splines off the studs with a flap wheel, or replace them with grade 8 bolts and nuts/lockwashers, and you won't need to pop the balljoints to remove the diff or change a CV in the future.
