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.
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
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 to replace a transfer case output shaft seal?
Use a hammer and smack the seal installer to draw in the seal into the output shaft housing. Step 3: Put the slip yoke back. Pick up the drive shaft and put the slip yoke back onto the transfer case output shaft. Make sure that you line up the timing marks that you made to ensure that the drive shaft goes back on correctly.
Why is there a seal on the output shaft?
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. This helps to keep the metal parts properly lubricated for long term use.
How does a four wheel drive shaft attach to a transfer case?
Some drive shafts on four-wheel drive vehicles are made of two pieces with a front slip yoke and some are two pieces with a center slip yoke. The two-piece drive shaft with a center yoke attaches to a bolted on, built-in yoke sleeve into the transfer case. The yoke sleeve is put into the transfer case with a snap ring to hold it on.
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.
