Buzzing noise

https://youtu.be/2722U1d4zq0
This isn't my video but this is the sound my tacoma makes at 20ish mph and at 40mph then goes away. Anyone know what it is??

 

I am having similar noise but not as constant. Mine is completely random. Have you figured out the issue?

 

I have not figured it out. It still makes the noise. I had many people look at it but they have found nothing and have found that it has no real effect on the trucks performence. I drove half way around the country and back with this noise and nothing went wrong. My guess is some old rusted bolts broke off and is rattling around some where. Best of luck. If you find anything diffrent let me know.
