Wife broke another axle in the xj, this time the passenger outer. I picked up a 1pc from a TJ but now it wont seal:shaking:. What do I need to do, go back to 2pc shafts or get a outer seal of some kind?

I've seen some nice outer seals for 30s, what gears is she running?

Unless it's been regeared I'd look for a junkyard front axle from a later model (95+) non-ABS XJ. Should have 297/760 sized joints, no CAD to fool with, etc...

the seal you need is spicer #46470. it fits in the cast housing on the axle tube and has the correct id for the tj shaft.

So this seal goes in place of the original seal that is inside the axle at the disconnect?
 
just converted to 1 piece shaft on a CAD YJ and we used a seal from Carquest. The seal we installed was inserted from inside the diff. Carquest had to cross reference these PN's to get us what we needed. The passenger side of the diff is not machined to accept the TJ seal so don't even try that option. As a safety precaution we put on a Alloy USA seal on the end of the tube just for good measure which will also help keep mud and water from getting into the axle housing and just sitting there where the old disconnect used to be.


Chicago Rawhide Part No: CR-11343
National Part No: 471763
470160 ( this is the one we used)
Quadratec Part No: 52420.12

Apparently not all axle housings are the same so not all numbers will actually fit since we tried more than one.
 
I run the US Alloy outer seals, but they aren't designed to hold the oil in. Rather they keep debris out of the tubes. Go with the spicer #46470 inner seal and that should fix you. You'll have to pull the shafts, diff cover and carrier to get to it. Might as well place the driver side while you're there. Either that or swap in a JY non-disconnect axle.

Let me know the next time you're going to URE or an event and I'll bring you my spare D30 shafts.

Not to hijack the thread but are you getting rid of the dana 30? What are you going to run up front?
 
ummm you may not want those shafts right now but when the ujoint splits and it messes up your ears,they sure would be nice. Ain't that right Rox-Mud?
 
Lifetime warranty on the chromos and I've driven it off the trail with trashed ears on more than 3 occasions. :D I'm kind've a break it and trailer it home to fix it sort of guy. If the joints do break I will be upgrading them to the Yukon super joints so I really have no need or desire to keep the stock shafts.

Anyways, back to what gotwood was looking for. :D

He stated that he already had a TJ shaft and now it won't seal. I mentioned previously not all D30 dico axels are created equal therefore it may need a one of several different seals mentioned above. Yes the Alloy tube seals are not specifically designed to keep oil in but water is thinner than oil and they do a great job of keeping it out.

And when was the last time I had that problem? As you know I swapped in super joints after that incident. At the time a BMFH straightened the ears and off we went, with your spare joint installed. That said, Ord.sgt.26nc is right that it is better to have a trail spare to pop in and repair the ears at home.
 
Gotwood,Rox-Mud and I wound up taking digital calipers and measuring both the inside of the axle tube where the seal would be and on the axle shaft itself and took the numbers to a parts store here in town and picked out the best one to go in there.Pressed right in and it sealed the shaft good and tight. To ramble off part numbers to you is a hit and miss at best.Take your time and get some measurements.I learned and this is what I will do for now on.
