SOURCE: Loosing oil on the output

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.

SOURCE: Loosing oil on the output

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.

SOURCE: Transfer case leak

You mean between the case halves? It is just silicon, no gasket. These are good for the pump wearing a hole in the rear housing and leaking oil. The cure for it is a new rear housing and a piece called a case saver that keeps the pump from doing it again. Taking the transfer case apart to fix it is easy, I can tell you how to do it.

SOURCE: 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 it....you need to put grease on the seal lip so it does not self-destruct before the normal lube can reach it.

Leaky front seal on tronsfer case


depending on if its is from the drive shaft or the main shaft either way you will have to do a bit of work if it is the driveshaft seal I believe you can remove shaft and change seal with case in truck but dont qoute me on that if not remove transfer case and at that point it is pretty much the same amount of work for the main or the driveshaft side. get yourself either a rented or borrowed tranny jack and drain fluid before removal make sure you have all little tubes and wires off before you try and wrestle it out have a friend around for saftey good luck be careful and hope this helps

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.

How do I do a front drive shaft on a 99 silverado? My ujoint is out towards the back. I can see the front just has the 4 bolts to take that apart. what I am wondering is if the back slides out of the deal...


I see that the solution given is for an axle shaft and not the drive shaft that was asked about. I am 99% sure that if you take out the bolts the other end will slide out of the t-case. Then the u-joint can be replaced as normally done.

Loosing oil on the output shaft of the transfer case, I changed the seal two times it's still leaking.


You may have pressure build up in the tranfer case and its going out the weakest spot which is the seals.Who changed the seals?Your transfer case may have a blocked breather if fitted
