probably the brakes, right?

Anyone heard this sound before? I just did diffs and gear oil but it doesn’t sound anything like a diff howl. I’m not braking, under constant acceleration, happens from like 20-30 mph and then the wind and engine noise drowns it out any faster. I took at look at the brakes, seem to be wearing fine, new rotors, pins and pads 1k ago, any help is much appreciated!

 

you can hear it best when im passing the Amazon truck, sorry for the sound you can barely hear it in the video

 

Try driving by a UPS truck and see if the sound changes JK. Try applying the brakes while you hear the noise and see if it goes away.

 

Bent brake shield?

 

The sound persists when braking, and doesnt change pitch or anything like that on turning the wheel. I'm gonna take the wheels off again and check for a bent brake shield.

If it helps in diagnosing any, the truck seems to not make the noise when cold, and seems to happen when the engine is fully warmed up...
