What is a transmission output seal?
YourMechanic. Jan 8th 2016 at 2:12PM. The front output shaft seal is an oil seal that is installed on the front of transfer cases. As its name implies, the front output shaft seal is responsible for sealing the front output shaft of the transfer case, keeping the gear oil or transmission fluid inside of the unit.
How do you replace an output shaft seal?
Step 1: Prepare the new output shaft seal. Get a tube of oil resistant silicon and place a fine film of silicon on the shell (outside area) of the new output shaft seal. Step 2: Get a seal installer tool that is made for an output shaft seal. Use a hammer and smack the seal installer to draw in the seal into the output shaft housing.
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.

The outer casing of the output shaft seal is metallic, and is pressed into the output shaft housing, sealing it externally as well. To keep tension between the rubber, watertight seal and the output shaft, there is a spring inside the seal that constantly applies light pressure inward towards the transfer case output shaft.
The output shaft seal, sometimes called the rear transmission seal or driveshaft seal, prevents fluid from escaping where the driveshaft yoke slips into the transmission. Front-wheel drive vehicles have two “rear” transmission seals, one for each axle.
Where is the transmission output shaft seal located?
