I think I maybe experiencing the same issue. It only seems to be loud enough to hear when I hit 70 and above. I just assumed it was the EL42's with wear on them. It's a low tone resonating noise I'm hearing definitely from the front. Seems to be worse when the temperature is fairly warm outside. Rotation of tires didn't change the noise at all. Anyone else experiencing these issues now?

 

I too am having this problem. Anyone else have this noise. Did you get your wheel bearings replaced?
