Hello,
I'm having trouble diagnosing a noise I hear while driving. As I get above 30 mph, a humming noise becomes very clear and gets louder as I increase speed. I know it is coming from the front passenger side. Any help would be appreciated. Thank you

 

Sounds like you need to replace the wheel hub bearing. It sounds like you already figured out it the passenger side.

 

The other possibility is the flex pipe.

 

Or the front wheel hub bearing
