OK so 08 Grand Prix GXP. I am hearing what sounds like a bearing noise...best I can describe it is it sounds like hot water running through a pipe. They have replaced the altenator and the power steering pump. They tell me that per GM Tech support that if you can't hear it over the radio it's normal. Sorry don't buy that.
Symptoms.
1. At an idle..in gear or park if you turn the steering wheel a few degrees in either direction the noise cuts in and out.
2. If you gently press the gas pedal..especially in gear you can hear the noise get louder and almost sounds like a gurgling sound.
3. The intensity of the sound is not consistant sometimes it is very noticable and obvious..other times you have to listen closely to hear it.
It was not doing this when I bought it...probably around the 34k mark. Was thinking maybe heater core BUT wouldn't make sense with the noise cutting in and out when you turn the steering wheel slightly. Someone PLEASE give me some thoughts on this. It is not power steering fluid. My bumper to bumper is about up so I need to figure this out asap.
