Might not want to hear this, but it could still be a wheel bearing, a rear bearing.
I once chased a noise around my car. Changed left front. Could have swore that's where the noise was, but noise continued. Changed right front. Noise continued. I took my uncle for a ride and he said his thoughts were leaning to the right rear. Changed it, and noise continued. As soon as I jacked up the left rear I spun the wheel and could tell it was the culprit. Changed left rear and noise was gone.
