Alright I have a vibration/hum when driving at higher speeds usually starts around 50 mph. When I have 4h engaged it goes away almost entirely but still can hear it a little bit. Anyone got any ideas what it is, I have changed all the fluids in it except for the transfer case.

Another note when I speed up past 50 it does get louder the faster I go.

Is the u joints the issue then by chance is the fact the noise reduces in 4h an indicator of that
