Yea I tried that and the noise I was hearing was gone so I am sure it was the rear driveshaft. But then when driving around in 4 hi there was grinding noise comming from the front diff when i got up to road driving speed. What could that be? Everything works fine just a horrible noise but not there when crawling or under 15? 
Grinding or more like a humming noise? Mine is pretty loud in 4wd High. It was just the extra gears in the tcase because more is stuff is moving around in there when 4wd is engaged
