Small main shaft leak....anyone else?

Main rear shaft out of transfer case throwing a little (red ATF). Of course the rear drive shaft throws it up under the jeep. Only about a dime size spot on ground when it sits overnight. Keep fluids topped off so I am not to concerned. Wondering if anyone else has this problem or has had to replace the seal???

As far as I am concerned it's just marking it's teritory. I also have a theory that if fluid can get out then water can get in.

Thanks in advance for any info.

Yeah, I have a small weep of it as well. Concerns me though, as it probably means the shaft is starting to go (or gone) out of true and will start to chew up the rest of the components. I really need to install an SYE...

No officer, that wasn't an accident. I did that on purpose...

I had the same problem after I put a suspension lift on and the cheap t-case drop kit, a new seal solved the problem

yeah, I have a 93 yj and the same .. the seal leaks a little. I'm going to change it on my next day of.. Tuesday.

It doesn't seem like a big Job. I alread replaced the ujoint there and noticed the leak.

All you have to do is take the clip that holds the ujoint and dive shaft off slide the driveshaft out, and pop the seal out. dont forget to try and drain some of the fluid first cause you know it'll leak..

I have heard taht you need a puller tool to take the seal off but if it's already damaged and you are replacing it.. you should be able to use a screw driver to pop it out..

I replaced the output shaft seal on a Nissan myself and it only cost around 8$ for the seal. so the Jeeps seal shouldn't be much more.

I'll let you know how it went..

theres my 2 cents worth.. hehe

I have a 4" lift with a SYE. However, I know several people with a 4" that are running fine without it (on and offroad). I don't really understand how different Jeeps react so differently to being lifted. Mine needed the SYE, but yours may not. It's something I would prepare for, so you're ready to do after lifting if necessary.

I replaced the seal last year for the same thing you guys are reporting. It fixed it for a period of time but it's beginning to "weep" again, but not enough to leave any on the driveway. I noticed that the shaft itself has a slight groove in it where the seal rides - probably from having grit trapped in there over the years and it actually abraded the shaft. If I have to change it again in the future, I'll probably replace the drive shaft with a double cardan if I can find one.

That seal is a normal thing to replace .. I do it every 2 years or so .. easy as pie to replace .. use a flat-blade screwdriver to pry it out .. and a small hammer to pound the new one in ..
