I have a 2011 Lariat Twin Turbo v6.
While driving there is a humming noise. Stops when I stop. Seems to get a little louder the faster I go. Has brand new tires. Still does it. It is NOT a 4wd. And suggestions?

 

Does the noise stop when you put it in 4wd?

 

Its not 4wd....

 

Re-read my question.

Okay, my bad. I should re-read your original post. Sorry.

Could be a bad wheel bearing.

 

Ugh. That's what I thought. Wonder how hard those are to replace? And the cost. I looked online for the cost for the whole assembly. It was in the neighborhood of $200-$300 😔

 

Not sure, I have never needed to do one on my truck. When weaving back and forth, does it get louder when turning in one direction versus another? That would be a tell tale sign it is a wheel bearing. Unless you happen to be unlucky and have 2 that are going and they are on opposite sides of the truck.

 

I don't know. I will try that tomorrow and see. Thanks for your help.

 

Good luck, let us know what you find. Maybe someone else that has had to do wheel bearings will chime in with the other info you need if it turns out to be that.

 

So I drove the truck and made quick turns left and right. Still did it when turning left but not so much when turning right. I also put it in reverse and drove it. Still made the same sound.
