Noise from back wheel

[scottvd]

Long time no post!

There is a noise coming from the passenger rear wheel of my car. It's only there after I've driven the car for awhile and things warm up. It sounds like rubber rubbing against plastic, it's not metallic sounding at all. I thought it was the CV joints since all four boots are torn; I replaced both complete axles and the exact same noise is still there.

Could this be the wheel bearing? I can't imagine what would make this weird noise, the noise is patterned with the rotation of the wheel. Any suggestions to diagnose this more? TIA!
