So I did a lot of searching and the closest I found to my problem is this thread.
When 4x4Hi is engaged I hear an increasing whine as speeds increases from 10+MPH. In an effort to troubleshoot the problem (and since I purchased this truck used and do not know the full maintenance records) I changed the fluid in the front differential and the transfer case. The noise is still the same after that. I read the above post and thought perhaps it is the U-joints but my understanding is it would do that all the time considering the front differential is always rotating but not "connected."
Although I know I need to replace the front pinion seal I'm not sure what else the problem could be... When switched back to 2WD the sound goes away immediately.
I understand there is always some degree of drive train noise in 4WD but this sounds more then "normal."
Thank you everyone for your help!
