That would explain how long it takes for the sound to go away when heating up. It also explains the fact that when it is making the sound I seem to be able to feel play in the wheels, or get the vibe that the wheels are loose.
Wait, your axles should have 0 play in them... they should only rotate, not wiggle. This may suggest center diff problems or some other onslaught.

The cv boots are loaded with grease, this heats up as use increases.
