I also still don't totally understand why this noise goes away when in 4hi. The left CV shaft rotates the same speed whether the vehicle is in 2hi or 4hi, it's just that the front driveshaft is engaged when in 4hi. But as I understand it, the bearing that is the culprit is the left side output shaft/CV bearing.

Correct. My guy told me half of the solid bushings he taps in are just for customers like me who have noticed the annoyance, and then there are the others who have their CV angles abrupt that bring the issues on so it puts excessive pressure on those rollers, he has never seen one fail, just wear marks on the rollers but mine was clean... so what can I say - its a design issue I guess, some make noise for no reason other than when it gets cold and there is shrinkage with that metal component - the shaft has extra play and it starts.
The noise goes away with the diff engaged because the other side starts turning, and takes the load off the drivers side CV on the roller bearing... mine did the same - engage the diff, noise stopped immediately (different bearing design on the passenger side shaft)
Anyway - the solid bushing worked for me thats for sure. Its been pretty cold in these parts this winter so it would have been moaning away for damn sure. Some people have said the bushing cured their steering wheel vibe at that magic highway entry speed but I can't say I've ever had that issue regularly. Thats another thing that comes and goes ever so slightly and only with the stock tires and ambient temps. Never on my soft Michelin snows, so who knows...
