Related Repair Advice
- The transfer case contains gears and bearings that are lubricated by oil. All oils and fluids in a vehicle should be changed as recommended by the manufacturer, or more frequently if you use your vehicle to tow or carry heavy loads.
- The correct fluid type should always be used when servicing the transfer case
- The transfer case may be a one or two speed design. Two speed transfer cases are commonly found in trucks and have a low range, which is used in severe conditions.
