What is a transfer case? A transfer case is part of your car, truck, or 4×4’s power train. It transfers power between the front and the rear of the vehicle by the use of drive shafts. One of the parts that can go wrong is the transfer case output shaft seal.

According to Timothy Charlet at Your Mechanic:

“The transfer case output shaft is the part that connects the case to the axle. The purpose of the transfer case output seal is to prevent fluid from leaking out of transmission, where the transfer case is connected by way of the transmission’s input shaft. The seal also helps to keep fluid from leaking out of the front and rear output shaft to the differentials, which keeps all metal components properly lubricated for extended use.

If the seals leak, fluid escapes and is no longer able to properly lubricate the interior components of the transfer case. Eventually the parts inside will wear out and overheat. If this happens, the transfer case will be rendered useless and the four-wheel drive operation will not work. Over time the transfer case output shaft seal can fail, and when it does, will display a few symptoms that will alert the driver that a problem with this system exists. Noted below are a few of the common side effects of a damaged transfer case output shaft seal that should be replaced.

The seal that keeps fluid inside the transfer case and thus the transmission is vital for the smooth operation of the vehicle’s transmission. When fluid is leaking from a broken seal, it reduces the volume of fluid that is currently working inside the transmission. A loss in fluid pressure also occurs, which will make shifting gears more difficult for an automatic or manually shifted transmission. If you notice that your transmission is having difficulty shifting to higher or lower gears, you should contact a certified mechanic as soon as possible to inspect this problem and offer a solution.” SOURCE
