Looking for info on rear diff rubbing / dragging feeling. It's a 2020 all stock. Ram dealer replaced the carrier but still having the rubbing sensation. This happens at low speed (under 5mph) and especially when turning. Could it be the traction control?

Or a brake dragging? Lift the back tires one at a time and spin them by hand and feel if one seems to be dragging. Will need to block off the front tires and place the truck in neutral. The driveshaft will spin with the tire too so it may feel heavy to turn

If it happens when turning left or right, it could be front wheel bearings. Are you sure it's in the rear? Is it a continuous noise? I had a "womping" sound in the rear end at low speed. Replaced rear wheel bearings, inspected gears, replaced rotors and pads. None of those helped. Ended up replacing u-joint at the rear axle. In my case when I raised the rear end on jackstands and tried spinning the tires by hand, I felt resistance at a certain spot.

It feels like a brake dragging, but it goes away once you straighten up and get going. Perhaps the traction control acting up?

Yes.. all from the rear end. Chrysler just put a whole new carrier in the rear to fix the problem but the problem remains.
