As far as I know the Grand Prix has something called Magnasteer, it's speed sensitive and changes the the amount of power steering delivered to the wheel based on speed to give a more "confident" feel to the driver, aka making it stiffer when necessary. If the ABS and TCS are not working (because of a bad hub bearing or bad wires, pigtails) I've heard this CAN affect the steering as the system doesn't know the car's speed. I thought this was more likely to happen on electric power steering like the Cobalts have rather than hydraulic power steering...My ABS and TCS are shot but my PS still seems normal.
