2020 Big Horn 4x2 slight incline turning vibration

[David Stewart]

2020 Big Horn 4x2 at around 55K starting having this strange vibration sensation in the rear when starting off turning left and right on a slight incline. There isn't a noise. It almost feels like I'm starting moving on rocks or a rumble strip. It's not something that passengers feel, but I can feel it and it's getting worse. Any suggestions. Getting ready to take into the dealership for the 60k service, and I know they won't recognize the issue. I've turned of the tracking control, and the MDS. Still get the same sensation.

Does the truck have the limited slip differential? Has the rear differential fluid been changed?

Sounds like the limited slip pack is broken. It is the most common part to break. I'm sure when they open it, they will find lots of metal. Hopefully they replace the entire rear for you under warranty
