I have 2022 Tremor with 30,000. I hear a fairly loud harmonic sound at 70mph when letting off the accelerator from 72mph. I listed to your video. Sounds the same. Taking mine into the dealer next week before my warranty ends.

I just dropped mine off. Going to take a week and a half to look at it. I would go somewhere else but they make you wait for an appointment which takes longer.

Same deal on my 22 stx 2wd.

Dealer refuses to acknowledge it so good luck.

Mine just started yesterday
Update: Took my truck to Bob Tomes Ford, McKinney TX. Senior drivetrain mechanic road with me for five minutes. Immediately acknowledged the issue coming from the rear. Said it needs a new ring/pinion gear set. They are going to order the part. Also said this was the first time he’s ever had to do one on a Ranger. I’ll update again after install to confirm if the problem is solved.

Thanks for the update. Im still waiting for them to tell me the issue. They didn't get to mine till yesterday. Service tech said they were working on tracking the noise.

I have a similar noise at lower speeds also, but it has always been there. Just a droning noise when you let off the accelerator. It's not terribly loud, but it is noticeable. It takes the faintest touch to the throttle to make the noise complete stop - like a toggle switch. I doubt it's a gear noise.

Mine got louder at highway speeds. Which is why i took it in. If it wasn't that bad, i would have just left it alone.

I am very curious to see what they find. Please keep us posted. I am concerned that mine will get worse as time goes by.

Just got informed that it needs a differential carrier part. Which i think is where the ring gear set pinion is. I'm not sure, that's what it said when I googled it.
