Prism has developed a "road noise" at highway speed?

Hello,

If the noise intensity increases with the speed, then it could be related to a bad wheel bearing.
It would be helpful if you could upload a video.

Can you tell if the noise is coming from one side or the other?

When the wheel bearing goes bad, it will make constant noise as you drive. And as the speed increases so does the noise.

Does the noise increase or changes when you make a turn? If the CV axle is faulty, you will get clicking noise when turning.

I have attached diagrams for your reference.

Please let me know if you have any questions.
Thank you.
