What to do if your transfer case output shaft seal is leaking?

Look at the transfer case output shaft seal to see any leaking gear oil. If your vehicle continues to leak oil from the transfer case after replacing the transfer case output shaft seal, then you may need to get a professional to take a look at the transfer case.

What causes oil to leak from output shaft seal?

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 causes oil to leak from transfer case?

If not it’s just one of those things. I can’t think which seal will cause this but someone will know. Most likely the garage has damaged one of the seals either on the input to the transfer case or the output of gearbox.

Where is the leak in the transmission shaft?

Photo # 1 shows the yoke plug. Our inspection discovered the plug that seals the end of the yoke had a small rust hole from the inside out. As the fluid traveled down the output shaft and yoke splines it leaked through the holes in this plug.

What causes an oil leak in a transfer case?

A leaking transfer case could mean that you’ve had a seal failure but it could also mean that there is an issue inside the transfer case itself. If a bearing goes bad inside a transfer case, it could cause it’s output shaft to wobble and thus causing a leak at the oil seal. This is true for many oil leaks if I’m honest.

What causes a leak at the drive shaft yoke?

As you can see, its much more obvious from this view that there is a larger area of surface oxidation on the inside of the yoke plug that could cause a much larger leak if left untreated. Photo # 3 shows the repair after the JB weld was applied and hardened.

What to do if you have a leak in the drive shaft?

The small hole was repaired with JB weld available from most auto parts and hardware stores. This can be accomplished by removing the yoke from the drive shaft, cleaning the area thoroughly; mixing the two-part JB weld and completely covering the plug area face up. The JB weld will flow out smoothly and harden providing an oil resistant seal.
