You say "...it only starts doing it when it warms up..." are you saying the noise is there when the car is cold or once it is warm?

 

Also, are you certain it's coming from the wheels?

 

Mine was making an annoying metallic rubbing sound when it was cold but stopped once warm. I eventually found it was the heat shield above the catalytic converter rubbing on the prop shaft. The heat shield lines the underside of the prop shaft tunnel. The shaft is set very high up on these cars and the cat hangs below it. Once the heat shield got hot it expanded and moved away from the shaft, therefore, silent once warm. The tell tale sign was scratch marks on the prop shaft above the catalytic converter.

 

My first fix was to rub high melting point grease on the shaft where the scratches were. This worked for a while but eventually the noise came back. I tried getting a new heat shield from Chrysler but this part appears to be unavailable. Therefore, I had that section of the heat shield removed. Its been a few months now and has been fine, the floor doesn't get hot and the carpet hasn't melted! But now it runs silent hot or cold.
