Whining noise with acceleration

Noises problem 6 cyl Automatic 60000 miles

First off, I am very bad at taking care of my car, so all of the problems I'm asking about may or may not be related. Right now I need to have my breaks fixed and also, when sitting on a minor hill, I practically have to yank on it to get it into another gear.

On to my problems.

#1. My car is making a whining noise that, at first, I only heard during acceleration. Now it's gotten to where I can hear it at all times, but seems to sound more high pitch when I accelerate.

#2. When I turn my steering wheel for a sharp turn, it makes a sound like it needs to be "greased" or something and just sounds like it's struggling to turn.

Do you
have the same problem?

First check trans fluid level, add as needed.

Jack up car, put on stands and inspect the CV boots for leaks/cuts/tears.

Also while up, grasp tire and push/pull both horizontally and vertically looking for any movement. If there is movement, check bearings, ball joints, tie rods, control arm and control arm bushings.

Have brakes repaired, either at a shop or yourself. New pads, turn rotors or replace, check brake hoses, fluid leaks, grease caliper slide pins or replace.

Have you found resolution to your car making a whining noise? Does it sound as though the noise is coming through the speakers? And continues even after the car is turned off?

We are experiencing this issue with our 2006 Grand Prix. We have been in arguments with two different dealerships as they can't seem to fix the problem.

We take very good care of our cars - so I question if your not taking great care of your auto is the true issue.

Help! We are stuck with an annoying noisy car!

I have a 1995 grand prix and I was having the same issue. Mine turned out to be a lose exhaust system up by the manifold. I replaced the flange and had them tighten the exhaust and it fixed the issue. I don't know if it will help you but it worked for me, and the flange only ran me about 15 bucks used.

Our car (2004 G.P) made similar noises. The shop said that it was the rack and Pinion steering. They said it needed more fluid. They said it is leaking internally through a seal(I'm guessing into a CV boot). They filled the reservoir back up and the sound went away. They said that eventually the steering will fail.

I have a 2004 Pontiac Grand prix GTP and it is making a whining noise under the hood. It also gets louder the harder I step on the gas. We have replaced the alternator so that is not the problem. We have started the car without the belts on and it doesn't make the noise anymore but if we just take of the belt that is on the supercharger it makes the noise. Were at a loss and just dont know what else to test.

Caradiodoc is prejudice against GM. LOL They actually have far less PS noise problems that other makes like Pord particularly. It sounds like a bearing in the supercharger is bad. That will have a separate belt for the supercharger so you can isolate that for sure

Its not the power steering pump as it doesn't make the noise when I turn but it could possible be the pully on the pump. We already took the belt off the supercharger and tested it and the noise is still there so its not that. So the only options we have are alternator(new), Power steering pully since the pump is new, Tensioner (new) Water pump, Crank, and A/c. I really dont want to replace them all to figure our what it is, that will be expensive. Do you know of a way to test this to find which one it is? We have tried spraying WD40 on each of them seperately but it didn't work.

The power steering pumps are the most common cause, not from the pulley, but from the buzzing of the internal check valve. We have already had instances where rebuilt pumps are just as noisy at first but the buzzing dies down over time. You can verify that by listening with a stethoscope at the connection for the high pressure line where it leaves the pump. This is common enough that we don't even bother to diagnose the generators or water pumps. A quick poke with the stethoscope is all it takes.

That buzzing noise is a lot different than the squeak or chirp from the serpentine belt. Don't use any type of lubricants or anti-squeal sprays on those belts as road debris and dust will stick to it and make the squealing worse. To identify a belt squeal, dribble a little water on the smooth side of the belt while the engine is running and the noise is present. If the noise changes, suspect one of the pulleys is misaligned. If nothing was recently replaced, that means the spring-loaded tensioner pulley is the most common cause. The pivot wears and lets the entire arm sit crooked, then the belt has to slide sideways across it as it goes around it. That sets up the squeal.

If the noise was not there until after something was replaced, check that item to be sure it's mounted correctly. The belt should be perfectly inline along all of the pulleys. Look for one where the belt is off-center compared to the rest of them, typically by 1/8" or more.

Noises problem
2006 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 75000 miles

I have a 2006 Pontiac Grand Prix and for the past couple of months I've noticed that when I acculate or turn the corners it whinings, it doesn't do it all the time but it's starting to get worse and it's really load.

Any ideas.

Thanks.

Have the front CV joints inspected for tears is boots/lubricant leaking, if you find anything they will need to be replaced.

Also inspect power steering pump/pressure hose and return hose for leaks, and check PS fluid level.

How much does CV joints cost to repair. The PS fluid is good.

Noises problem
2006 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 60000 miles

My vehicle has had issues that started near 60,000 miles. The car will make a high pitched whining noise with startup and slow accelration, then goes almost completely away during coasting. It was just happening once in a while and then became more and more apparent. I take very good care of my vehicle. I have also had past issues with steering. The steering wheel would give a thumping vibration while turning the wheel. I took it in several times and finally found a dealership to fix it. The tires on this car do not stay balanced either. I have had my car balanced three times since January and I still feel a vibration. I have been VERY disappointed with this vehicle purchase and will never purchase another GM car. The Grand Prix is nice to look at, but a let down as far as integrity. To other owners: I fee your pain!

Check fluid level in trans. With engine running, fill as needed.

The whining may be low fluid level in trans, or could be an assy. Driven by the serpentine belt.

The alignment issue is most likely a failed front end component, ball joints, tie rods, bearing, control arm bushing etc.

My car is making a whining noise that sounds like it's coming from behind the engine on the driver's side. The noise happens under most conditions: in park, while accelerating, the only time it doesn't make the noise is when I put the car from park into drive but keep my foot on the brake. I was told it could be my transmission fluid filter so I recently got it changed but the noise is still there. It can't be a belt because they're on the other side of the engine.

If your car is supercharger equipped it is normal to hear a whine when you see the boost meter engage.

I can hear it louder when I lean closer to the dash. So I think it is coming from under the hood, not rear end.
