2022 RAM 1500 4x4 Rear Diff issue

[Ram_Yak]

Hi all, just got my truck out of the shop, repaired under warranty with 33k miles. The issue was the rear differential was making grinding noises.
Tech notes: Replaced the carrier, front and rear pin bearings, axel bearings, and carrier bearings due to metal contamination and scared races. replaced the axel seals, pinion seals etc.
Bought used in 2024, towed a 26ft RV a couple times that should be well within towing specs for the truck.
Just wondering how many other folks have had this issue with such low mileage and any ideas on what might cause this issue other than just defective parts?

Definitely not a common problem I've seen posted about. I'm glad they took care of you under warranty, as they should.

Just an observation, I typically see people with differential trouble have lift kits, over sized tires, and I think if you combine that with the relatively low payload of the truck being less than 1000 lbs in the higher trims you can exceed the advertised limit. a 26 foot RV might have a 500-700 lb tongue weight leaving only 300-500 lbs for passengers, luggage, and cargo. I'm not saying you went over the limit but I understand why people move to the 3500 if they are bringing 4 people, plus luggage and cargo, and pulling a travel trailer for a family getaway.

On the flipside, there are people here who travel all over the USA towing a travel trailer behind a half ton without issues.

My guess is you just got unlucky. Fortunate you discovered this while you are still under warranty.

If you suspect you will frequently tow and this might happen to you again outside of warranty you may consider switching to a 3500.
