2022 Ram 3500 Laramie with ~ 2000 (yes, two thousand) miles and the front differential starts growling in 4WD hi or low. Take it to the dealer, they drain it and see "a lot" of metal in the oil. They are replacing the whole differential assembly and believe it or not the parts will be here next week. Funny, the day I drove it off of the lot I could feel a low vibrating hum through the steering wheel , gas pedal, and the seat of my pants. I've never driven a vehicle or operated a piece of equipment feeling something like that that didn't eventually break down. I have a feeling that hum will be gone once the diff is replaced.
I've scanned through many of the threads and have seen no one else with this issue, has anyone else here had to deal with this yet? The dealer said they had a similar job with a 2021 with 60k miles and they had to replace the spider gears. The service rep ordered the parts while I was there and he said systemwide there were 6 orders and 30 part sets on the shelf. I hope this is a limited issue and all I'll have to deal with on a BRAND NEW, EXPENSIVE truck. The world we have built for ourselves, I guess.
