What’s this sound

Tech said he heard it but said it was wind noise. I don’t know. Had them do the 10000 mile maintenance and made sure they torqued the wheels correctly, it seems to have quieted down and not as defined but seems to still be there.

 

Sounds like a 5 second warning your truck is about to blowup.

 

Only heard with the back slider open?

 

Does the sounds get faster and slower with speed? My carrier bearing made a similar noise

 

Consistent sound at above 50ish,and only there when your kinda feathering the throttle. You can hear anything below 50. It’s weird.

 

Said he could slightly hear it when closed.

 

Wouldn’t you hear it at lower speeds and at all times?

 

I wonder if they adjusted the handbrake.

 

Or airflow.
Any roofracks?

 

Not that I’m aware of.

No roof racks.

Kinda sounded like a Floor tom with a high pass at 250

 

Well 5000 miles with the noise and nothing is broke so far. Well that I’ve noticed anyway. So does anyone think that it could be echoes under there from the the rear diff noise, cause I think I got that too. Go figure. All opinions are welcome even the sarcastic ones. Lol I could use a laugh right now. I’ve probably worried way more than I should.

 

Do you have access to a camera, or microphone that you could mount at different locations under the truck? It might help you narrow down the source.

Or have a buddy do it Indiana Jones style.

 

Lol! Don’t have either.

 

Well took it back again Friday and the service manager rode with me and says he don’t hear anything “abnormal”. That’s 3 times I’ve had it at that dealership. I have an appointment at another dealership on Friday. Hopefully I can get some answers.
