Weird noise

[TRD4Runner4Life]

My 2017 sr5 has a humming vibrating sound when cruising at low speed 40mph. It makes that sound every second and a half. I feel like it’s coming from the front engine and I feel it from the gas pedal as well. Help! Thanks

subbed, have similar in my 2012, didn't start until recently, 140k miles. I just put KO2's on it and think that might be part of it. Also suspect wheel bearing or differential.
