Rhythmic "Harmonic" sound while driving

Has anybody noticed a rhythmic harmonic type sound while driving? Sounds like it's coming from the wheels. On mine it comes from different wheels depending on my speed. I notice it at 12 mph the most and at this speed it sounds like it's coming from the front wheels. Once I speed up it goes away. It's just a pulsing type sound. Thanks for any help or ideas!

 

You must have the TRD Harmonic Edition.

Yea, I haven't found any that pertain to what I'm hearing though.

 

Welcome OP, and congrats on the new truck. What you might be hearing is the howling sound that many have talked about. search "howling". there is even a TSP to address this.

Do you mean that howling sound that causes pedestrians to turn around when you are approaching from behind?
Nah, I've never heard it.

Ch78 just hooked you up.

 

Hey, thanks for the replies! It's not the lower control arm howl. I have that just haven't plugged the holes yet. It's not the diff either. It sounds like a rhythmic pulsing sound coming from the wheel turning. Only at 12 mph. Not sure if it's a vibration from the wheel spinning only at the speed for some reason. Does it on pavement and off-road.
