One possible factor is your driving speed. Or more accurately the wind speed
through you bars. A standing wave sets up and when it does it creates a noise. I've heard a hum sometimes.

It's about the harmonic resonant frequency of the wind, now that the air has two bars, or nodes, for that standing wave.
There may be other factors, too.
I've been a satisfied long-time Yakima rack customer, and they are strong. Good luck with yours!
