Yes. The transfer case oil needs to be changed every 100,000km (change around 80,000 because of the conditions of Pakistan) using Hypoid 80w-80 gear oil gl-5 spec. The transfer case takes around 0.57L (570ml) of oil. Rear differential oil needs to be change every 2 years or 30,000km and takes Ammix ATF D3-SP. This is basically automatic transmission fluid. A good quality one will work. The rear diff takes around 0.73L (730ml).
