Can someone point me in the direction of a good how-to for replacing axle seals on a vac disco D30. It may be straight forward enough but I wouldn't know cause I've never even had the wheels off.

Nobody?

I'm not much help...you do know there is a search feature for the forum?

I did search, I found a great article on how to replace the seals in a non vacuum disconnect axle and some information about the passenger side seal being in the disconnect housing on the vac axle. Seems like you need to do it different because you can't just gut it like you can a regular one.

Here is a good web site to look at, http://go.jeep-xj.info/ the guy on here does almost all of his own mods and show how to repair a lot of stuff

Found this; Looks like you gotta take the fork off to extract it.

That's the one I found, awesome article but non-disco.

Looks like it, it's really not that important I can figure it out, just hoping somebody had something to save me some time. Ill snap some pictures of it so maybe the next guy can have a heads up.

You gotta pull the right axle, install the seal from the disco housing hole and pull it into place with a special tool. Some people have made a tool with a piece of all-thread.

Really? I'll be dipped! Do you happen to know, did they put "command track" on other axle's and if so does the seal go in silly with those also? Also in the above process /\, they forgot to put on the wheels! (makes me feel better).

Ok so the right axle is 2 pieces I'm assuming. So does the inner axle just pull out too so you can get the diff carrier out to do the left side?

There are guys here who should know better than me, but I'll take a guess. I saw posted yesterday by a guy who's pretty slick, that there is a retaining clip on the inner end of the inner axle section. In the diff you remove some pin to let the axle in to remove the retainer? The left axle being pressed and bolted one piece may not have the retainer, just slides out with the hub off. There is some trick involving using an extension or piece of pipe and the power searing to press the hub off. You might not need to mess with that inner axle. Also removing the diff carrier is probably not something you really want to get into.

Just pull the outer axle.
Command-Trac from 84 to 90 had 2 piece. All Selec-Trac had one piece. Command-Trac 91? and up had one piece axle.

From what I understand you can pull the diff carrier out and put it back as long as it goes back exactly the same although I'm gonna try my best to avoid it.

I've gotta pick some parts up from the Jeep shop in town on Monday so I'll ask them too.

I appreciate the help and I'll post some pictures when I do it so hopefully it helps someone else.

Command trac and selec trac are the t cases. They have nothing to do with the one or 2 piece axles
