2024 Badlands - Unknown sound

[FourHorses]

Hello:

New Bronco here. Less than 700 miles. I noticed this sound at low speeds the second day of ownership. It is the higher pitched whine as I drive over the camera. It is a manual transmission Badlands. The sound is at low speeds but not at idle nor does it change if I rev the engine. I believe it is in the rotating drivetrain past the transmission. The speed of the sound does run at a higher rate if the revolution of the vehicles speed is increased. Meaning it goes faster if I am going faster. It slows if I slow. No change if I’m in neutral, clutch in or out. Stops when the vehicle stops but is still running. Only thing I haven’t tested is it rolling while not running. Thoughts on what this could be before I take it into the dealer? They already have one of my Fords currently.
Thanks

Another sound clip.

I can't really pick out the sound in the videos but that was a pretty cool shot rolling over your camera! The sound could just be the newness of the drive train breaking in.

Agree with @PWillette -- cool video, but I don't hear anything unusual in either of them

Not to say you are hearing things, I just can't pick out anything from the videos. The first there's a lot of Doppler effect, the second just sounds like normal idle engine / road noise rolling down the road, and I can hear you rev the motor a bit.

Very very interesting. I hear it very much in both videos, but I guess I know what I’m listening for. My son hears it too, he heard it the other day and didn’t know anything about it and asked me what that noise was. Interesting indeed. Hmmm. Anyone else hear anything? Maybe I’ll try a different video.

That second video almost sounds like the common front driveshaft squeak.

That’s what I think it is. Almost sounds like a belt whine to me, but it’s from underneath.

The second video has a whirling sound.
My Badlands has less than 500 miles, and I do not have that sound.
I do have the 2.7 however and the 10 speed auto.
Transfer case related…???
I wonder if it changes when put into 4WD?

Does it happen when the vehicle is parked and idling? Does it make the noise for a short time after the engine shuts down as well? I have a similar noise.

{I have the same sound} only when driving at very slow speeds into my drive way our to of my suburb street at less than 15kmh….

badlands, 1200 km, 2023…. 2.7 auto.

No, only slow speeds after fully warmed up. 20 minutes or so after warmup.

Exactly!

Well I have done the squeezing of the boot and the flexing the boot forward and back trick. It solves the noise for a couple days, and then it returns. To me it 100% verifies the problem is indeed the front driveshaft squeak. This one is frustrating because as previously mentioned, this type of problem requires the vehicle to be completely warm, but the dealer lets them sit overnight and then goes on a quick 3 minute drive and can't reproduce. I have an appointment Friday for my first oil change. I'll see what they have to say. I am not leaving it with them, they've already had my expedition almost 3 weeks waiting on warranty parts.
