I have a 2006 f150 fx4 with 80,000 miles and i have this humming noise that is driving me crazy!. it sounds like its coming from the left front of my truck. So i have replaced all 4 of my tires with michelin ltx ms2. I also have a replaced the wheel bearing and the noise is STILL THERE. I'm pulling my hair out i am out of ideas. what else could be causing this loud humming sound......?

Is the noise at all times or when accelerating, at certain RPMs, sitting still? Just trying to get a little clarity because it could definitely be different things. If while driving but not standing still, it could just be the weather stripping in the airbox. That wears away and causes noise, I had a noise, changed that for about $3 and no more noise. Good luck and keep us updated.

That was my next thought also... check the foam around the air box.

It's only when moving it's deff. Coming from the wheels under the truck. The noise sounds like mud tires. I ruled that out I already replaced all 4 tires and the driver side hub bearing

4x4 actuator. My drivers side was making noise, replaced that one, and it ended up being the passenger side. Dealer kept telling me it was my tires. Took the truck back 3 times before they replaced the actuator and it was gone

Where's the 4x4 actuator?

Yours was humming? Mine isn't grinding just humming. Do you think it's my passenger or drivers side? Noise seems to come from drivers side
