Weird noise

[TRD4Runner4Life]

I have a 2017 sr5 4runner lifted with 285 70 17 duratracs and I’m getting a humming vibrating sound driving at 40mph only but it goes away at higher speeds. It sounds like it’s coming from the engine but I can feel it from the gas pedal. Don’t know what is causing it but help if anyone knows. Thanks

If it's speed dependent, it's probably harmonics related to your tires.

Sounds like your front differential needle bearing. Put it in 4 wheel drive and see if the vibration goes away or while making a right hand turn. There is a TSB on it and you should be able to get the dealer to replace it under warranty.
