After extensive searching and researching, I have ordered the parts. I replaced wheel bearings at 80,000. They were shot. Now at 83,000, I am going to do the diff/axle needle bearing replacement. Hopefully within the next few weeks. My vibe/grind is now really bad. And the play in the axle at the diff is real bad. I'll try to remember to take pics and document it. I am not planning on replacing the axle, but if it is damaged I will do with a cardone.
FYI, I wrote Toyota corporate about this issue. Here is the "canned" reply
