2008 Toyota Prius - Wheel bearing

Believe the passenger side wheel bearing needs replaced.

And what leads you to this conclusion? Noise? Vibration? Similar symptoms can be caused by a bad cv joint.

Roaring noise. No vibration.

Assuming the tires are in good condition you’re probably right.

Yeah the tires are new.

Ok , if you are correct and this is not something you can replace your self then have it looked at before the silly wheel falls off.
