JohnC specified the oil stain is on his '99 K1500 - those stub shafts ride in bushings - if the stub shafts indicate side play, the bushings need service.
Isn't that what you're talking about?

AFAIKT there's a bearing in the housing where the stub enters the housing. I think RJ is correct: the other end is positioned by the sidegear which fits in a recess in the carrier. If that recess wears the side gear moves and the axle can rock up and down and wreck or at least open the seal. (Gotta be good for the gear, too!)
No one has access to the SB I mentioned on page 1?
On normal axles, there isn't usually a whole lot of speed differential between the axle and the carrier: only that difference due to the differential action. With the GM CAD the carrier is pretty much stationary and the axle spins at road speed when in 2WD. On the FWD axles I'm familiar with there's a fairly hefty tube extending from the side gear thrust face through the carrier bearing that supports the stub. The outer end of the stub passes through a roller bearing in the housing. Never had a problem with that setup.
I think we may have solved the problem. We threw (a lot of) money at it. The solution looks like an '07 Yukon...

Ok...never mind - and, congratulations.
ronniejoe, I've not worked on the small front axles, and have only a not very good drawing of such for info.
What appears to be bushings may also appear to be needle bearings, also with little radial thrust capability
Intent was to suggest pull and repair it, as opposed to replace, but that one is moot, for now

The deal's not done yet. I broke my own rule: never sign a deal the same day as the test drive.... Now I gotta figure out how to get a better deal...
JD: I think RJ's point was that the wear occurs in the carrier and thus the carrier needs to be replaced. My staring at the blowup diagrams makes me think that's probably the case. Hopefully I'll never find out for sure...

Update:
Deal is sealed. Got another $4500 off
These new vehicles are so loaded with and dependent on electronics, I broke another rule. Sprung for the 7/70 extended warranty...
