Where is output shaft seal on transfer case?
Where is output shaft seal on transfer case?
The output shaft seal rides on the yoke sleeve and the sleeve is stationary (it does not move laterally). The two-piece drive shaft with a front yoke slides onto the output shaft of a transfer case. The output shaft seal rides on the front yoke and is in constant contact with the yoke as it moves laterally during driving conditions.
When to replace front seal on transfer case?
The transfer case is not made for any routine maintenance, however, if the transfer case fluid is leaking from either the front or rear seal, one of our expert mechanics needs to remove and replace the seal to prevent damage inside the transfer case.
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 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.
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.

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.
