Is there an OUTER axle tube seal kit for 2022 JT?

[WILDHOBO]

Im hearing you shadow papa...my concern is that it was clearly diff oil leaking out through the outer axle tube...if only 1 outer intermediate shaft bearing failed, why was the inner seal leaking diff oil? Perhaps the wobble in the shaft...however ive been complaining to jeep service about diff whine for almost 11 months...ive done more than 10k km in that time.

When city jeep changed the diff oil 2 months ago, the diff whine went away (axle tube wasnt leaking oil at that point though).

Can i ask...how does the FAD get lubrication?

Mine doesnt appear to have any drain or refill plug in the FAD for oil. If there is a seal between diff and FAD...how does FAD get lubricated???

The fad is lubricated directly with diff fluid. It drains right into the housing when you change diff fluid.

How does diff oil drain through to FAD given theres a seal on the inside the diff pumpkin? (image is taken from inside diff)

There is on the non-fad side of the axle, but per the service manual, there isn’t on the fad side. Just the one outside the fad housing.

So that means i only need ro replace the FAD housing outer axle seal...which is the stupidly expensive one

I am trying to find a "blind bearing puller" large enough to remove the failed bearing outer ring...unfortunately, the standard spare parts stores around here dont have kits thst go above 32mm. This one is 52mm.

Ive to a few place...most of them had no idea what tool i was even describing ...the one that did doesnt have one large enough

going to have to fabricate something up to do this.

It beats me why it is such a pissy bearing is even used here...its only just over 1/4" thickness for a 42mm/52mm (axle/housing). Thats f#$%ing stupid...no wonder they fail so easily.

Also, did anyone take a close look at the photo i published earlier of the bushing in the intermediate axle assembly kit? It looks to me like its made of plastic...WTF!!!

I sent you a dm.

I have taken long pieces of threaded rod, and turned down pieces of steel, drilled a hole in the center, and flattened two of the sides of the round steel a bit. You can then tilt the steel piece to get it behind the bearing, straighten it up and put a long bolt or threaded rod through it............

I know, I'm making it sound simple because it's simple if you have a lathe and mill, not so simple if you don't.........
But I've also stacked large, thick washers to do the job. Still if you can't get to the back of the bearing, you need to flatten two sides so you can tip them into position behind the bearing.

Some of the AMC differential tools I have have similar shaped pieces for pulling seals and so on.

This isn’t that complicated. He has a new shaft, bearing, split ring, etc. just cut off the race and pull the snap ring. Then remove and slide the shaft out.

My question would be - is that outer bearing race a snug/press fit, or will it simply "slide out"?
If the balls - some or most of them are out, the shaft and inner race still on it may pull out, then work on the outer race in the housing.

Interesting to note that the FAD hasn't really changed design in 40-50 years!

Biggest difference in the older stuff is that intermediate shaft bearing is a needle bearing.
Otherwise, decades ago, a bearing (bushing) in the end of the intermediate shaft that the nose of the outer shaft rides in.
I need to go through the front diff on my car as I notice the outer shaft has some "wiggle" to it and I feel a slight vibration in 4x4 mode on the highway. But it's holding up a lot of weight with that half-shaft and CV joint (talking the car, not the JT)

It doesn’t matter. The bearing slides on from the left, or differential side, so needs to be removed prior to sliding the axle out.

Im hearing you guys.
I dont habe a lathe or mill...im kicking myself because my plan earlier this year was to build a lathe, however, ive spent almkst the entirety of the year away, so havent had the time...

I will fabricate a puller up today...im sure with a drill press, multifunction welder, plasma cutter, grinder, steel and some elbow grease, ill figure something out.

I had already made my own diff spreader that works fabulously well...so this shouldnt be difficult.

My plan is to go and find myself a big mother fucker high tensile bolt, reshape the head into a chisel type profile so it sits in behind the outer bearing ring, wedge it into position, attach it to my slide hammer...im sure the outer ring will come out pretty easily.

None of that is necessary. Just cut it off. It’s a broken part.

I have a feeling you'll get 'er done!

You make do with what you have. With a plasma cutter and grinder, I have confidence you'll get something made.
Sounds like what you need is to be able to buy some TIME.
The plan sounds good.

Back before the days of "essential tremor" in my hands, i could take my torch and notch one pieces of exhaust pipe and not even bruise the other. I could cut bearings off of shafts, cut them out of differential housings and so on and never leave a scar on the part I didn't want to hurt. These days - not so easy.
I've sliced bearings off of axles and never left a mark. Now, it's left more to the dremel to make a slice or use the press where I can.

With your youth and tools at hand - yeah, you'll get there.

The best tool in your collection is ............. patience. Nothing else matters if you lack that.
And believe me - with my condition, I have precious little of it.

Ive got the outer ring out.

Dremel+flexible extension...a bit of cutting, then a hit with cold chisel and its done.

That's pretty much what I've done with bearings stuck in axle tubes or similar.

Now you can move forward!
