Noise in front Passenger side

[trimer]

All

Need some thought before I take to a mr fixit. Since I have had my box...about 4 months now, I have noticed that I have this noise coming from my passenger side...seems like the front end. It is almost as if you are blowing into the end of a straw or a bottle of beer...that sort of low horn type of hum...

This only happens for me when I hit around the 42-47mph mark. quits when I give it gas...mostly happens when I am coasting. I originally chalked it up to maybe wind hitting my car in an odd way like it was going through a vent or something,...again like you were gently blowing on the hole of a bottle of beer or something. very faint, but enough to notice it.

Any thoughts? Wheel bearing perhaps???

Thanks for any insight...
