2001 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 150000 miles
I have a 2001 Grand Prix GTP Supercharged and since May 2009 I have had whining noise coming from the car. It is loudest inside the car. The history is: power steering line was replaced due to leak, system was flushed and refilled. Noise continued. Power steering pump has been replaced 4 different time with Delco parts, the rack and pinion has been replaced. The noise continues. The power steering was just flushed again today and GM power steeing fluid was put in (apparently the mechanic was using something else). The noise is still there when the steering wheel is turned left and right. Loudest when turning left. Any suggestions?
