You should get a transfer case service every 30,000 miles (48,000 km) – 50,000 miles (80,000 km) using manufacture recommended fluid. Check your vehicle owners manual for specific differential service interval. If your vehicle is 4-wheel drive or all-wheel drive than it has a transfer case. The transfer case transfers power to the front or rear wheels as needed depending on the design of the vehicle. If you have a rear-wheel drive vehicle, power goes to the rear wheels until you need 4-wheel drive. You might have to shift lever or press a button on the dash to go into 4-wheel drive, or it might even go into 4-wheel drive automatically, depending on your vehicles design. Some all-wheel drive vehicles are primarily front-wheel drive and transfer power to the rear wheels as needed. It is very important to have a transfer case serviced regularly. Transfer case fluid cools, cleans and lubricates the gears, chains, bearings, shafts and other transfer case parts. As with any other fluid, your transfer case fluid breaks down over time reducing its ability to clean and lubricate the moving parts of your vehicles transfer case. This can cause premature wear within your vehicles transfer case and lead to costly repairs or even complete transfer case replacement. 4-wheel drive and all-wheel drive vehicles are equipped with differentials that also require servicing.
