High pitched whine in a 17 Ram 2500 diesel.

I have a 2017 Ram 2500 diesel that has a high pitched whine that seems to come for the passenger side of the cab. Noticeable between 20-35mph. Any ideas or solutions?

It maybe just the turbo spooling if it follows the engine load/rpm.

Thought about that, but it shifts gears within that speed and it sounds more like air going through a crack.. it’s that kind of whine.. checked the cab over lights and they are all tight, drove with mirrors in and windows open… just can’t find the problem… but it doesn’t sound like the turbo.

Check under the hood for leaf debris buildup trapped up near the bottom of the windshield. I've driven myself nuts with noises before, only to realize it was a damn leaf. Especially, with a certain MPH range that it comes/goes.

take off your cabin filter see if it still doing it.
