YJ Axle Seal
My son and I replaced the front passenger side outer axle seal on his
93 YJ the other day and it is still leaking, actually it seems to leak
worse. I pulled the vac disconnect cover plate and checked and the
seal seems to be still seated properly so I got to thinking it might
be one of the following.
1.) the axle had a bit of scoring on the part of the shaft that mates
with the seal ... could this cause a bad leak?
2.) the inner seal is totally shot and overwhelming the outer seal?
Any thoughts?

The inner seal doesn't do anything that the outer seal doesn't do. That is,
they both prevent the shift assemby's dedicated oil supply from leaking
into the axle tube between the inner seal and the right side carrier seal,
or out the end of the tube.
The oil supply for the shift assembly does not come from the the
differential, it has to be added to the shift assembly through the 4x4
indicator light switch hole any time you open the shift housing up. You DID
put oil into the shift housing after you replaced the outer seal, didn't
you? If not, you've likely toasted the whole magilla. If you did, then the
seal isn't properly seated, was damaged when installed, or the outer shaft
is damaged at the sealing surface.
As tough as those are to get seated, I'd opt for the first two possibilities
I listed.

3.) You bent it putting it in. (Pretty common happening I hear. I was
told to buy an extra for the first one I did.)

Re: YJ Axle Seal
If you don't have the factory tool this is a bear to get pressed in without
ruining the seal. I still have a tool I made for these hanging in my shop
somewhere. Even with that I generally ruin one or two before I'd get one in
there fully seated.
The disconnect axle is absolutely the worst piece of Rube Goldberg nonsense
ever installed on a Jeep.
