Lets play diagnose the sound, another chirping video

Hey Fellas, below are a couple videos of me trying to capture the noise, sorry for the background noise in the truck, we know they aren't quiet inside.

Chirping starts around 50-60 mph and stays constant as long as I am above those speeds. Road condition doesn't seem to affect the noise, not that I am going that fast on dirt roads anyway.

Chirp does not happen going over bumps or anything, only has speed stated above.

I have an airflow snorkel with mount drilled into the a-pillar, but this sound started in September and I have had the snorkel for way longer.

So, I am thinking it has something to do with wind being pushed through, just not sure where. I have not had chance to sit shotty and diagnose, as it's not on my wifes high list of priorities to drive me around in my own truck...

Just trying to see if anyone else recognizes this bastard or could point me in a couple directions.

Appreciate the help

day time vid to see general area of where the sound is coming from:

video at night, so you can't see anything, but noise may be clearer:

Does the noise change with blower fan speeds or on/off?

 

Nah its constant, speeding up (mph) is the only thing which affects the consistency/volume of the noise, which is why I am leaning towards wind resistance interacting with something as the culprit.

I just need to make my wife take me for a freeway spin and stick my head down there...

 

We had a weird noise for a while with a model body change once. To find it, we ended up using tape (blue tape style,) and started taping seams. There was an issue with a gap in the side view mirrors. Another one we found was a gap in the windshield molding along the sides of the windshield. Once found, a line of black silicone was the fix. Invest in a roll of tape and have at it. Good luck.

 

You could try taking the antenna off to see if it goes away.

 

Any update on this? Same issue and also a snorkel. Replaced tie rods, hub assemblies, sway bar links, cv axles, drive axle and brakes, rotors, calipers and still have the damn noise
