ok so i replaced the 2 piece axle shaft a few years back to a single piece one but now its leaking :brick: i tried to install a new seal in the passanger side of the axle tube right beside the carrier and it bent all to heck installing and is still leaking after searching on here ive seen that there isnt a seal for this location on the 2 piece shafts so do i just need to replace the one where the disconnect box use to be? does anyone have the part number for that seal?
-
They have the other years and models too. on this one look at #26.

thats the one i tryed to put in it this last time and its still leaking do you know if it would maybe go by what the shaft itself is out of? only problem with that is i have no clue what they took it out of other than i believe they said it was a cherokee
-
Just maybe since youbent the 1st one up maybe you should put in one not bent.

x2, if it was bent would leak
-
I've heard that there are multiple different diameters of seals for the passenger side of the carrier. figuring out which one your axle needs is the hard part. (ounce you find the kist of what possible seals it could be)
-
if it's the wrong ID should be easy to check.
-
This is the info I've run across: 471763 a National number same for Carquest and Oriellys
-
yea i gess i have the wrong ID for it becouse it didnt just bend on one side the whole lip after the step up bent in i to make itself smaller im gonna pull it apart this weekend and see if i can find a way to measure the ID of it then comes the fun part of trying to find the right one parts are a pita to find in germany thanks for all the help

This is one that goes in the axle disconnect housing when using a TJ shaft in a YJ D30.

i'm pretty sure the 2 piece axle uses 2 seals on the passenger side, with a 1 piece you only need the inner one if i'm not mistaking.

i'm not so sure about my statement above anymore, i will look in the FSM to see if i can find a parts list, seems that they use only 1 seal in the disco housing on the ones with axle disconnect, i have no idea if you can actually install one in the diff housing like in the TJs with 1 piece axle, if the axle does not have the seal seat machined for the disconnect seal position then would probably leak.
-
I have read in various forums that some YJ D30 have a seat by the diff and some do not. In any case, it seems the safe bet is to put a seal at the disco housing anytime TJ shafts are used.

would the 1 piece shaft have the smooth surface for the seal in that place to properly seal (couldn't avoid the repetition) since is supposed to have the seal by the diff?
-
I think the aftermarket axles sold as "disconnect eliminator" have a proper sealing surface, but not the stock TJ shafts.
-
i did this swap a few months back and researched many forums as to what seal needs to be used. i tried the national 471763 and ruined prob three seals trying to get it seated next to the carrier. the proper seal for my 95 yj was napa part #11800. bought one of these and installed it with no issues. been running my tj shaft without any leaks for months now. you only need this seal near the carrier. you no longer need the one outsde the disco housing. that one was there to lubricate the shift fork and collar which you no longer have. just get the new seal seated squarely and make sure the seal is in the right spot so that it will be riding on the machined portion of the new axle shaft and you should be good to go. if i can be of any more help please let me know

You might end up with water pooling in you disconnect housing. AFAIK the national 471763 is supposed to be placed at the disconnect housing, not at the diff.
From reading a bunch of write-ups it seems like not all D30 are the same. Some have a place for a seal at the diff, others don't, and several part numbers are mentioned as working in specific axles.
Here is a list of some that might work:
Chicago Rawhide 11343 (Same as 11340 just a bit deeper sides)
Napa 11800
National 710068
National 471763
Spicer 42500
Superior Axle 470160
-
very true i never thought about water pooling in that void. my main reason for not installing a seal at the disco housing is that i would not be able to tell if the carrier seal was leaking. it that seal leaks now i would see it at the end of the axle tube. if i had a seal outside the disco it would hide this and poss allow my fluid level to drop enough to damage my carrier without knowing. if you could get a seal that sits ouside the disco that would keep the fluid in that would be all you need but i think that the tj shaft would tear it up since it is not machined at that point for a seal. the national 471763 and chicago rawhide 11343 are interchangeable and i tried both. im pretty sure they are meant to be put near the carrier but i didnt have any luck with them. they are very close in size to the napa 11800 i used successfully. the area outside the disco takes a significantly larger outer diameter seal.
-
there is an Alloy USA disconnect eliminator kit that comes with seals and a block-off plate (no axle shaft). From what i remember in the instructions they had only the outer seal installed when using a 1 piece shaft, but that was with their replacement 1 piece axle, if using a TJ shaft the story is probably different.
