In replacing my final drive unit, I've noticed the right output shaft. Seems logical there is a bearing in there that works as hard as any other. I see you can buy the bearing, but how do you get this apart? It runs true and quiet on the bench, and has no play. I'd like to inspect this bearing, and at the least, repack it. Any suggestions? Thanks.

I also worried about that, especially with 175,000 miles on mine. Like
yours, it was quiet and true. I replaced it anyway so I wouldn't have to
wonder about it anymore. It is a sealed bearing and very inexpensive,
readily available, and easy to replace if you have the axle already removed.

Sir:
http://www.bdub.net/manuals/X7525/X7525.pdf
section 3C-4&5
CAUTION: Final drive axle fasteners are an important attaching part in that they could affect the performance of vital components and systems, and/or could result in major repair expense. They must be replaced with one of the same part
number or with an equivalent part ifreplacement becomes necessary. Do not use a replacementpart oflesser quality or substitute design. Torque values must be used as specified during reassembly to assure proper retention of this part.

Steve,
I kinda agree / disagree. I too am an anally retentive perfectionist and
when I disassembled the front end on The Blue Streak I decided to change
that bearing.
It is a rare bird (especially Downunder) and I had to pay over $100 AUD for
it at the time.
When I pressed it off the output shaft and compared the brand new one to the
old one (had done about 70,000 miles) they felt exactly the same as far as
play goes. Obviously I couldn't tell if there was any internal problems as
it is a sealed bearing so being a.r.p. that I am I put the new one in
anyway. I kept the old one in case someone Downunder needed one and wouldn't
hesitate giving it to them as a replacement.
See what I mean about agree / disagree?
Jim K stocks them:

BTW has anyone had one of these bearing fail?

Rob,
Same as you. Zero difference but as long as I was making everything new,
it was destined to be replaced before failure. I did have a Caddy one that
was very bad. I looked closely and found out why. Someone must've hit an
obstruction because when I bead blasted the pan, I could see where the axle
had worn a hole in it and it had been brazed up. That was what pushed the
decision to replace it on the GMC while I had the axle out. No sense in
waiting for it to wear out and take out the pan.
