How to change a tranfer case - Grand Cherokee Jeep Cars & Trucks

Park your car in a safe place and make sure you have enough space to work around it.Raise the vehicle using a floor jack and safely support it on two jack stands. If you have a four-wheel drive model, the transfer case is located center-left of the car. Lift the left side and position the jack stands near the front and rear wheels. If you have an all-wheel drive model, the transfer case is an integral part of the transmission. Lift the front of the vehicle.Working from underneath the vehicle, locate the drain plug at the bottom of the transfer case and place a drain pan underneath. Using a wrench or ratchet, remove the drain plug. After all the transfer case fluid has been drained, reinstall the drain plug. Do not over-tighten the plug to avoid damaging the threads. Remove the drain pan from underneath the vehicle.Locate the filler plug on the side of the transfer case. Clean the filler plug and the area around it using a shop rag; this avoids contaminating the new transfer case fluid. Using a wrench or ratchet and socket, remove the filler plug. Add the new fluid to the case using a small funnel. Add oil until it reaches the bottom of the filler hole, then reinstall the filler plug but do not over tighten it.Lower the vehicle.
