Whining noise with acceleration

Noises problem
2006 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 98000 miles

My car makes an awful noise everytime I turn the wheel. Its a loud whine and I don't know what I can do to fix it. Also after about 55 mph the whole car starts to shutter and wobble. Please let me know if I can fix it or do I need to take it to a professional. Thanks

It is making a loud whining noise (like a loose belt almost). Now the steering wheel when I turn it makes a grinding sound.

To keep an adequate amount of fluid in it has been cumbersome to say the least. Money is tight as my failure to fix properly. I now have a whining sound that is evident right from start up. It gets louder as I accelerate from a stop

My car has been making a super loud whining noise when I push on the accelerator. It does this about 90% of the time. I've had a number of oil changes and am very suprised that no one has mentioned that I should have it looked at or anything. Any ideas?

As soon as I put car in gear it starts whining sound appears to come from the driver side and it whines the hole time it's in drive I can shift to neutral and whine quits.

Steering problem

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?

Thank you

Hi:

The lines have not been changed to my knowledge and yes, the wrong oil was used with all pumps and the rack. I am going to guess that my next step would be to have the lines changed to see if that does the trick, if not, then there is a possibility of having to change the pump and rack and pinion again. Correct?

Thank you so much!

Hi Mark:

Yes, that is an option. I have a few friends that I can get to drive the car for me. I will let you know how this goes in a few days when I can catch up to them to have them try this.
Thank you!

I have a GTP and when running it has a high pitched whining sound, like a tight rubber band. As I put the gas down, it gets louder.
If anyones has any ideas. If you do, is it easy to fix?
The car does not seem to have any less power or hesitations.
Thanks, Terry

I had all the problems in my 2008 Pontiac Grand Prix mentioned above: Whining while turning or accelerating which seemed to be getting worse. By the time I found this forum and excitedly went to tell my hubby (the car guru of our home) that this seems to be a common problem with Pontiac vehicles and that the steering fluid system might be the problem, he was already way ahead of me under the car trying to determine if the steering fluid was leaking out of the pump or lines. He knew there had to be a leak because a few days ago, when he had suspected the issue was related to steering fluid being low and had topped it up, the noise seemed to disappear and I drove to work the next day in perfect silence; but this success was short-lived as the trip home was not as quiet. (Incidentally, the leak must happen when I am moving because there was no hint of any leakage where I park.)

My hubby found out that the leak was in the hose, evidenced by the clean piece of metal right under the hose (Yes, I got under the car too and spied the evidence.) On removing the cover (insulation?) of the hose, he saw a crack in the return hose. (Of course it had to be the one part that no auto shop in this area keeps in stock...and also the one that would be a real pain to replace!) I am attaching an image of the culprit (below), but here's a link to the image as well: https://ibb.co/TYZLKrK (The part where you see the break is where the crack was. It was not completed split like that; he cut it at that weak point in order to be able to make clean cuts on either end to remove this section.)

He decided to improvise and fix the problem with what he had on hand rather than wait for the not-so-cheap replacement hose from the factory. Since the return hose is not the pressure hose, he figured he could replace the damaged area with a rubber hose fastened to the rest of the hose with metal zip ties. It seems to have worked because my car is no longer making any noise as I drive, accelerate or turn corners.

So all those who said to look for a leak in the steering fluid system were right on the money.
