Supper, again nice job! I like to see that. Btw, to go the 9th mile a guy can slide a longer piece of the next larger shrink tube up also, to make a really bullet-proof connection. (with two layers, the outer longer). I do some solar stuff where a short could burn the house down!

Well today when I took the wag to the tire shop to get my tires rotated and balanced (that fixed my steering wheel shaking problem at 55+mph) , they told me I have an axle leak. The leak is in the passenger side front and I am assuming it just needs a new seal. I have been looking up on how to do this process and I am still in need of handy info. Thanks

It would be nice if you filled out your info. (you might need a computer) Looking I found it's an 87. The right axle seal is in the Disco housing. That one is a very tough job. If I knew of a shop that screws people, I'd get a quote in righting, than have them do it. It's a real booger.

At least part of my mistake was to not "sandwich" the seal on a perfectly aligned shaft. I just tried to pull it in square. Buy at least two, and put some silicone in the "home" is all I have. Or move two doors from Cruiser.
I'm no nub, and that one, won. I sliced some tendons that your left hand uses. This might be a rare case (other than playing guitar), that you really need those left fingers! It pisses, I get radial spin-out on the inside of the tire, only when I use 4wd to pull a trailer up my hill though.

Lets hope I don't have to ask cruiser for his address lol.
I just want to get my understanding right here. There are only two seals that sit in the front axle on both ends of the diff housing correct? And oil is going down the axle shaft where it is not supposed to be at and leaking out at the ends before where the u-joints, capilers, rotor..etc are at. From quick research and web surfing, it looks like the rear axle is the opposite because the seals sit at the ends with the bearings and it is easier to replace because they're right there?

Most. "meaning not us with "command track", have their seals right in the differential, with dry axles out to the hub assembly.
Now "we" have the Vacuum disconnect 1/2 way out the right axle, and a two piece axle. The disco has a cover where the diaphragm, the fork, and the vacuum lines all get together. The fork slides a sleve over the axle splines to make them one, then after it's over the unit shoots vacuum up to that blue switch, right of the expansion bottle to light the light that tells you it had indeed moved over. The disco is "wet", and the axle seal is in it's housing, on the outboard side.
Just a ****ing Beautifull ***** setup
I'm sooo glad they made it that way. 



I think the disco is pretty neat, but the seal replacement is unusually lame. When you are done, loosely loop a long zip tie to hold the vacuum lines on it. Without that every armadillo you hit will knock it off.

Did the passenger side axle seal on my 88 the other day and that was a "fun" half day process but now it doesn't leak anymore. Even though that is probably the worst place for a seal.

Did the lights today and now all 4 and off road lights turn on. Decided to wire it with my existing relay for the hella 500's. Love it.
Alright thanks for the information flintstone. Sounds like putting in the seal is the hardest part after all. Will run to the junkyard tomorrow to get a new seal.
