2022 Gladiator with burned up rear differental.

[Jerry C]

My 2022 Gladiator with 47K burned up the rear diff 2 weeks ago. The truck does not go off road and has stock size tires and wheels. Jeep cannot get parts to the dealer for another 45 days. Anybody else have issues like this?

Not common at all since after they first came out. I have an early gladiator and I was unfortunate to have one with an early failure, but they swapped out the entire assembly and sent it to Dana to see where it failed. I didn’t care, it allowed them to fix it faster and I didn’t have to rely on the dealership to rebuild my rear end.

You have an axle leak and run it low on fluid? Water ingress?

Running 40s on 3.73s? lol.

I have 3.73 limited slip. No leaks. I do pull a trailer that has a total weight of less than 3500 lbs. 5 or 6 times a year, never no farther than 6 or 7 miles. No off-road playing. Always keep it in the gauge. Stock size tires and wheels. Dealership did order a complete rear end.

That wouldn’t be enough to hurt anything. I tow all the time. More than that and for a lot further. Ironically, I started after my rearend failed. I do wonder if you had a bad axle seal, which is common, and it ran low.

Warranty covering it?

Jeep will pay for it. I'm just without a truck for another month.

Just curious; did they find the gear lube at the proper levels?

Just guessing the crap factory lsd blew up and the fragments ate the bearings. My ram rebel did the same, but fortunately I heard some squeaking and found it to be rocket hot after a relatively short drive. New gears, bearings, and a tru track went in and it was good for the next 60k miles I owned the truck.

Yes but burned and full of metal.

Yes was full of fluid

What kind of squeaking? And where/how did you notice this? How many miles?
- Asking because I'm getting an intermittent squeak in the rear at lower speeds, similar to when brake pads are low and more noticeable when near a wall/building. I had the tires rotated yesterday, they said the pads are 8-9mm at all 4 corners.

I think it was around 80k miles. Similar to the brake pad squeak you describe. Put my hand on the diff and it damn near burned me. At that point it went into the shop as I figured it was a bearing issue.

Good to know, I'll be testing this later today and every so often until May when the Mopar warranty runs out. Then I'll check it every month or so until I hit 97k miles and the Toyota Warranty runs out.

Both of my rear differentials (first one was replaced at 20k) started making a squeak for the first 100’ or so in the mornings after a rain. I replaced my rear differential fluid at 59k because it was starting to make noise when turning and I wanted to make sure there were no issues before it ran out of warranty. The fluid looked good. No surprises. I refilled and added the Mopar friction modifier back and the noise went away and it still works. I had to test it. Lol

Yeah, pretty sure I could benefit changing the fluid in mine too. Mine doesn't always leave the marks quite equal lengths, granted I'm in a manual with 3.73s and 32" MTs.

I do manage to consistently get the advertised 0-60MPH times (according to Tazer) with this setup. Maybe I'll either locate the pic proof, and/or try again in spring. This was with new 255/75r17 MTs weighing about 49lbs each.

I just used the valvoline squeeze bottles because it’s easy. They are supposed to have friction modifier included but I didn’t trust that. You walk a fine line because too much and it won’t work as well. I used roughly 4/5 the required additive amount and I got lucky and guessed it right.
