I am an 08 Saturn owner with 110K on the car. I had a similar issue, among many others with this car and my vibration was due to a bad rear wheel bearing. Right rear to be specific. I changed tires, rotated, balanced. You name it and ultimately, I had a bad rear wheel bearing. My car is an FWD XR model. Hope this helps.
