grind noise from rear of chrysler

I have a Sebring with 110,000 miles. It has developed a grind noise recently that seems to come from the right rear wheel area. Nothing seems to be bent or rubbing. It gets louder at highway speeds and when turning left, turning right it lessens. It doesn't seem to be exhaust related as it doesn't occur when I give it more gas.
Possibly the wheel bearing on that side. Jack the car up and support it safely and spin the wheel by hand and listen for the noise. if you can hear noise, remove the wheel and the brakes. Then spin it again. If the noise is still there, it is the bearing. If noise goes away, it is in braking system.
