Truck Repair: 95 gmc 4x4, gmc 4x4, gear lube

Question
Was hoping you could tell me the recommended lubricant for my transfer case(95 GMC manual shift transfer w/auto trans.) also the same for the front and rear axle.

Answer
automatic trucks 4x4 use the same as the transmission dexron III now the front and rear ends should use 80\90w gear lube if you taking this truck off road lets say every weekend you should be changing the gear lube monthly..any other questions on this just ask.thanks
