If your breather is fine, then most output shaft seal leaks can be attributed to a worn bushing in the tail housing. I'd grasp the drive shaft and using an up and down motion, see if there is excessive play. If that's the case, you'll need a new bushing. hope this helps.

Transfer case leaking is there any vent wholes

The short answer is yes, most transfer cases do have a vent hole or more likely a vent tube. It seems troubling that you have any fluid coming out of it, though. It's much more likely that the leak is from a shaft seal than the vent tube. It would be well worth your while to have a drivetrain specialist look at it to ensure that it isn't a bigger problem.

If you're the do it yourself type person, here's some ideas to help you track it down. Generally speaking, there is one input shaft and one or two output shafts, depending on the setup. Check to see if you can see damage to the rubber seals which protect the actual shaft seal. A torn boot is a pretty good indication of a problem. Look for any actual formed drops and follow them back to where they would have come out of an oil bearing body. Remember to take gravity and wind into your calculations as oil always flows downhill and with the wind. Changing the seals on a transfer case can be challenging but it's a good job for a backyard mechanic.

If you're not mechanically inclined and familiar with repairing drivetrains in general, it's likely going to be faster and cheaper to have a trained mechanic do the repair.

Leaking Transfer Case

most Gear boxes with transfer cases have an oil seal between the main gear box and the transfer case so that the oil from the box is not passed through to the transfer case causing it to over fill. If there only a few spots under the car you have time to find exactly where the leak is. May be only an output shaft seal. Check the level of the gear box and transfer case your self It will be level with the filler plug. The oil used is either sae80-90 or oep 80-90. Check manufactures specs on this. If it turns out to be the seal between the two boxes then it will require the unit removal for seal replacement.

Transfer case rear output seal leaks

Likely either the shaft has a wear scar on it that's too deep for even a new seal to compensate for or the bearing that supports the shaft is worn. Other possibility is that the same tech is installing it dry every time he replaces need to put grease on the seal lip so it does not self-destruct before the normal lube can reach it.

Transmission fluid leaking back, 1988 Ford Bronco

your output seal on the tranny or input seal on your transfer case is bad. you have to pull your transfer case to tell. this is a pretty straight forward job. block wheels. put transfer case in neutral. drop front and rear drive lines.diconnect transfer case shift linkage. there is a short commponent connecting the trans to the transfer case. the bolt on either end face each other. remove the bolts to the transmission. the transfer case is heavier than it looks, i suggest getting help. pull back on the transfer case until it will drop down. it will pull out a bit because of the trans output shaft. replace what will probibly turn out to be the tranny output shaft seal and reassemble in reverse order.

2000 Jeep Cherokee Transfer Case Leak

Clean the area off with a degreaser and watch it. If it is an input or output seal leaking, you unbolt the drive shaft going into the case, remove the nut that holds the u-joint flange on, pry the old seal out and tap the new seal in (be careful not to tap too hard or the seal will bend)

90 percent of the time stop leak does not work. Usually the seal between the transmission and transfercase goes out and forces all the fluid into the transfercase and leaks out the rear seal. Or the tranfercase or transmission breather could be plugged.
