2018 Ram 1500 Sport- Loud spinning/grinding noise when coasting or when cruise control is set.

[Floyd1975]

2018 Ram 1500 Sport w/118,000 kms. When im driving in the city and coasting at 30-60 kmh or even when cruise control is set to 70-90kmh, theres a loud spinning/grinding noise coming from under. If you can imagine a big metal ring spinning freely on a metal pipe-is the best i can describe the noise as. How I quite the noise is basically just rev the engine a little. Any help on this would be greatly appreciated.

Following as I am having the same problem and solution by revving. Truck sat over the winter with little movement as I was driving another vehicle. I am beginning to think it may he an actuator that is trying to disengage due to a broken vacuum line, will investigate.
