np205 grinding

Well the problem I am having is I have a np205 "married" transfercase that grinds. It doesnt grind all the time it only does it when I get going about 25-30mph down the road and let of the gas it will grind then re apply throttle and grinding starts again. Let the truck get back down around 5-10mph and accelerate and no noise. It only does this when in 4wheel drive. In 2 wheel drive with hubs locked in it just makes a wind noise like a gear drive on engine. Any help will be greatly apreciated.
