21 Tremor loud humming noise

[Diggman08]

I was driving down the interstate today going around 70-75 and intermittently got a very loud humming noise. When I slow down it would stop. I feel like it's a drivetrain issue maybe a hub. Any insight ? 33k miles ecoboost. 2" ready lift.

Can I post a video here you can here it

Could be your hood. I had exactly the same symptoms at the same speed and figured out it was wind making the hood hum. Raised the adjustable hood stops to put more pressure upwards and it stopped. I’ve also stuck some washers under the inner stops that are non adjustable because I didn’t like how cranking the outer stops up until the hood had less play at the latch made some panel gaps appear, so I dialed those back some and have stuck washers under the middle part to raise it evenly at all 4 points of contact. No hum since.

Interesting. It was very windy yesterday with that front coming in it was kinda pulling my truck crosswind. Funny my first instinct thought it may be air pushing through. But was yours that loud? This was like really loud. I was like oh shit and hit the brakes. I guess I can see if it comes back. Hate to go to dealer and get a diagnostic fee and they say everything looks good.
