Many things can cause transfer case grinding; shift forks, broken gears, bad bearings, anything really considering a transfer case is made up primarily of gears, sprockets, chain, and bearings. Hope this helps!

check CV joints, if bad replace shafts and joints assembly
The grinding is a worn CV joint. Get it replaced before it causes more damage! A worn wheel bearing will make the same noise answer worn wheel bearings or worn brake pads will be the cause
main shaft bearing
If the grinding is only while turning *not* while applying the brakes, I'd say check the CV joints? If it is while breaking, check your disc pads. Ina any event, good luck with it.
Your brakes are dragging, likely the pads are worn down to the steel. Hope this is helpful, www.TunerTools.com
