I am sorry for the long wait
will it make this noise if you try it in 4HI ?
ok let me know
this usually means there is an issue with a front hub / bearing or some kind of issue if the front axle assembly
make sure both front hubs have no up and down play in them and that both front axle shafts are not damaged at all or ripped boots
if that all checks out and the drive shaft from the transfer case to the front axle is nice and tight then i would have the front axle lube changed and see if this noise goes way
if it does not it would need to be lifted in the air and see if it can be duplicated up in the air and try to narrow down this noise area to the front axle or the transfer case area
