What is a transfer case output shaft seal?
The output shaft seal is the part of the transfer case that connects the case to the axle. Its job is to prevent fluid from leaking out of the transmission and to keep fluid from leaking out of the front and rear output shafts to the differential. These seals can dry up, wear out and break.
Why do you need a transfer case output shaft seal?
This is basically what makes a car a four-wheel drive. The transfer case output shaft attaches the case to the axle. The purpose of the output seal is to prevent fluid from leaking out of the transmission, where it connects to the transfer case. The seal also prevents fluid from leaking out of the front and rear output shafts to the differentials.
What causes the output shaft seal to bend?
This puts a lot of stress on the output shaft seal and makes the seal bend. When the seal is hard, bending the seal will allow fluid to escape the transfer case and allow dirt, debris, and water to enter into the transfer case. The most common sign of output shaft seal failure is the drip of gear oil leaking from the seal.
What are the symptoms of a bad transfer case output shaft?
Common signs include difficulty shifting gears, grinding noises coming from underneath the vehicle, and jumping in and out of four-wheel drive. What is the transfer case output shaft seal?
What happens when you break the transfer case seal?
If you are having difficulty shifting between gear ranges, there may be a problem with the transfer case. When fuel leaks because of a broken seal, it reduces the amount of fluid that is inside the transmission. The car will lose fluid pressure and that will make it hard to shift gears no matter what kind of transmission you have.

How much does it cost to replace oil seal on transfer case?
The average cost for transfer case output shaft oil seal replacement is between $212 and $254. Labor costs are estimated between $162 and $204 while parts are priced at $50.

Why does my transfer case output shaft sweat?
Any fluid leaks should be addressed immediately to prevent internal damage from low fluid. Seals such as the transfer case output shaft seal will normally sweat due to the output shaft rotation. The transfer case yoke and driveshaft is reinstalled and the vehicle is taken off the jack stands
