    I have a grinding noize occurring in my 94 S10 Blazer. It is not constant but is getting more frequent and lasts longer. It happens when in 2WD but goes away when I shift to 4WD high however, after shifting to 4WD there is a knock that happens after a couple seconds and repeats sometimes but only after driving a couple minutes. The grinding sounds like gears not meshing and sometimes starts after hitting a bump. Does this sound like a tranfer case problem?
