What happens if you push in the clutch and coast when the noise is occuring? Any change? Any difference in the noise between 4th & 5th gear?

If the noise is still there when coasting with the clutch in, I would suspect a drive train problem. I would drain the fluid from the tranny & t-cases and see if there is any metal in it on on the drain plugs.
