Leaking axle seal?

[Chance575]

The issue no one is bring up is the dust and dirt which is getting in too. Mine had a lot of crap in it and smelled bad.

How do you propose the "dust and dirt" is getting in?

I'd ignore the smell - that's not unusual for some fluids. I've got some synchromesh fluid that smells like dead fish - new in the bottle. Smell is usually meaningless unless it smells burned in a differential with clutches (LSD)

About 1300 mi, good so far. Who confirmed '22s don't have the issue anymore? I sure hope so.

Back in the '80's. Think Jeep was the one that had a lube/fluid the smelled like bananas. Because it was made with bananas. You had the shake the shit out of the can before opening, because the banana fibers would settle out to the bottom of the can. I'm thinking it was tranny fluid.

Transmission lube for the T4 and T5 and I believe the 176 in the mid 80s was AMCs 89 83 000 000
Had a nasty smell but made those transmissions shift smooth as silk.
The modern equal is Pennzoil's Synchromesh fluid.

Here we go again, plus an interesting development if the dealer isn’t full of it.

I took my truck in to have the little battery checked because I was getting an error message for the start/stop system. I asked them to take a look at the axle seal as well because it looked like it was leaking again (noticed it about 5 months ago). We were all hopeful that it was residual from the first repair.
It wasn’t, definitely leaking again. However they couldn’t order the part. It took them a day of phone calls but apparently DANA is redesigning the axle. So the dealership told me that once they can order the new part they will fix my leaking axle. Until then they have determined that it’s safe to drive. Which is funny because they had my truck for over 2 months last year since they were worried that it wouldn’t be safe.
Does anyone have any insight on this axle redesign or is it BS?

In other news, I asked for something fun as a rental while they were working on my truck. I ended up with a 2021 Dodge Charger Daytona with the 5.7 hemi. IT WAS SICK! I will probably catch some flack for this but I have definitely been pricing them out on the website and considered trading the JT for one. The problem is I would still need a truck but I absolutely fell in love ?

Interesting on the axle. Maybe someone seen how much it is costing to replace all of those axles.

Try the 392, better yet a HellCat.

Hah yeah that’s the obvious choice, but, $$$

Others here have gotten the same message - orders are halted, it's in engineering or something but they can no longer order these parts. At least a couple of others have heard the same thing.
Obviously the numbers hit some threshold, they were finding that replacement axles were not doing the trick so they started replacing entire axle/differential assemblies, that wasn't a total fix........
It all still makes me wonder - why not the 2020 model year? Why 2021? What changed?
Have we seen ANY 2022 model year JT with axle leak?
Have we seen ANY 2020 model year NT with axle leak?
If not, why not, what's the difference, and if the above two questions are "no" then why not go back to the 2020 rev or move forward to the 2022 rev?

Or is all of that wrong and there have been 2020 MY leaks, or 2022 MY leaks?
But if not - then I would think the solution was simple - back up a couple of years and use the 2020 revision?

Thanks, that’s good I’m not the only one. Maybe they are actually going to figure it out now ?? I agree, wonder why it seems like a specific period of time that the leaky ones happened in. My wife’s 2021 JL has been good so far and it’s at about 13,000 miles.

2021 Overland Diesel with 12K and I have the leaking right rear. Was told I had to wait till June for parts availability. Hopefully it will be an improved version.

At least we're seeing something happen with the overall issue. I'm gonna wait until I see concrete evidence of an actual repair before I go in for round 2.

So, I have to ask and I don’t care if it’s a stupid question.

(setting up the ground work first)
If our roadways and sides of the road where we typically drive on and park are slanted toward the outside edge/ditch/sidewalks so rain water runs off the road, ideally,…the passenger side of the vehicle is angled lower than the drivers side, right? So oil will flow toward the right side more than the left side which means there isn’t the same amount of oil on the left side as there is on the right, right?!

So if we all stuck with a leaky right side and dripping on the wheel and the brakes as we wait for a true fix, why not drain out a 1/4 quart to see if the right leak stops. I’m guessing at saying a 1/4 quart, I don’t actually know how much to drain to equal the amount the left side is down. Get what I’m trying to say?

For some fairly old tech, solid axle seals, this whole issue is very strange and complicated. Incuding why the old fix works for some (knock on wood, mine is still bone try after 5k miles) and not others. Why it seems to be prevalent mostly on 2021s but they need to engineer a new solution, rather than revert back to what worked in 2020 or what is seemingly working now in 2022.

Hopefully once the new fix is released, Jeep will see fit to share what went wrong. Until then I will continue checking mine every month or so since I don’t have complete confidence it won’t reoccur like it has for many others who got the same fix I did.

LOL - I see your "logic" but that's not how these work.
Seals seal even if they are sitting fully under oil or lube.
They could be up to half-way under oil, or even fully have the backside covered in oil and it won't matter. They can also typically hold back at least 7 pounds of pressure. In fact, a little pressure holds them tighter against the shaft.

But think of a crankshaft oil seal, or the seal on the vertical shaft engine sitting on a rotary lawn mower - all of that oil is above the seal.
There are plenty of applications where seals like this work partially or fully in oil, submerged, etc.

There's also some out there that are already running a bit low.........
And then you have some roads that have little crown.
