You can hear the belts whine on my eclipse and when I turn my wheel either the power steering goes out at times, or sometimmes it causes my engine to rev. What could be wrong??

You didn't list your engine size, so I'm going to assume that it's the 2.5L V6. The engine operates several components via the serpentine belt including the alternator, a/c compressor and power steering pump. This belt also has a tensioner pulley that maintains good contact between the belt and the driven components. A whining sound indicates that one of the components is presenting greater-than-normal resistance to the rotation of the belt. If the noise stays at the same frequency whether or not the a/c is turned on, I would rule out the a/c compressor. Next, does the steering wheel turn smoothly in both directions? Does the sound remain the same when you're turning the wheel? If yes to both, I'd rule out the power steering pump. Does the whining get higher in pitch when you step on the accelerator pedal? If the answer is yes to this and the other questions, I'd lean toward the tensioner pulley being the problem. If that is what it proves to be, I would change it AND the serpentine belt at the same time since the belt may have endured unusual wear due to the tensioner. Good luck.

I doubt it.
Usually when the pump fails it smokes the belt.
If the steering wheel will not turn and the fluid is contaminated, I would say the problem is the gear box or rack and pinion depending on the make model and year.

hi Eva.
As you turn your steering wheel it is this fluid pressure that aids in turning the wheels of your car. ... If the pump impeller is trying to move power steering fluid and starts catching air bubbles it can cause whining noises and vibrations to occur.
Maybe you've heard it at a stop light. Maybe you've heard it as you pass a car on the freeway. Or maybe you've heard it in the parking lot at work when someone is leaving. The unmistakable whine of a power steering pump can make even the most confident mechanic wonder when that car will breakdown.
Power steering pump noise is a unique noise that your car may make and once you've heard it you always know what it is. The noise is a mix of a whirring and a whining and will always vary with the speed of your engine whether your car is driving or in park. This whining noise can be subtle or extremely loud and may be worse in colder weather, or right when you first start your car.
Power steering pumps are most often vain style centrifugal pumps that are tasked with pressurizing the power steering fluid and pushing it down to your power steering gear or rack. As you turn your steering wheel it is this fluid pressure that aids in turning the wheels of your car.
There are a few reasons why you are hearing power steering pump noise from your car. First, it may simply be due to the design of the pump. Sometimes, noisy power steering pumps can continue to work flawlessly for years after they start making noise. This may simply be due to the manufacture's design or a tight tolerance in that particular pump. In this case, you would hear the noise but not see any other adverse effect like a loss in power steering, leaking fluid or a wobbly pulley. In this case, you may be able to help reduce your power steering pump noise by choosing a different type of power steering fluid, like a synthetic fluid.
Your power steering pump may also be making noises due to air trapped in the system. If the pump impeller is trying to move power steering fluid and starts catching air bubbles it can cause whining noises and vibrations to occur. Even tiny air bubbles you cannot see that are trapping in the power steering fluid may be causing the whining you are hearing. In this case, the best thing to do is flush your power steering system to try and remove the air from the system. Having air trapped in your power steering system can be difficult to diagnose so you may need to simply try a power steering flush to see if it solves your problem.
Power Steering pump noise may also be due to a failing power steering pump. As the bearings on the impeller go bad it will start to make noise as the pump is turning. If you have a bad power steering pump you usually will also experience leaks from around the pulley, a wobbly pulley, or difficulty turning the steering wheel when you are stopped. If you have multiple of these symptoms together, it is probably time to replace your power steering pump.
Lastly, and most usually, a whining power steering pump is an indication of a low fluid level. Your power steering fluid is probably something you have rarely if ever checked, so it often comes as a surprise if the level is low. Your power steering fluid reservoir is also relatively small so even a slow leak will cause a low fluid level relatively quickly. To confirm this is your problem it is as simple as checking your power steering fluid level. Some power steering reservoirs are clear so you can see through them to check how full they are. You may have to wipe away some dirt and grime to find the "full" line, but it should be easy to check. If you have an opaque power steering fluid reservoir there should be a small dipstick under the cap that will help you measure the fluid level. If it is low, then you have a leak somewhere and topping off the fluid should quite down your power steering pump.
If you discover a power steering leak, rather than simply continuing to add fluid every time it gets low, you should fix the problem permanently so you don't have to continue to check your power steering fluid level. Replacing lines or seals can be a surprisingly difficult task due to the location of your power steering pump and steering gear or rack. The easiest way to seal your leak is to do it from the inside out!

If it is when you work the steering it could be the power steering.
Check the fluid level in the reservoir. Centre the wheels, start the engine and remove the lid on the reservoir. Turn the steering all the way to the left. Now turn it all the way to the right. Repeat this 'lock to lock' action four or five times.
Turn the engine off and recheck the fluid level. Top up if needed.
PUT THE RESERVOIR LID BACK ON!!!
If this doesn't fix the problem you will need to get the steering rack and power steering pump check by a good mechanic.

Power steering pumps whine when they are low on fluid, or if they are goin bad. Serpentine belts also whine in cold weather or when they are goin bad. Tru spraying just a little WD40 on the belts when its running, if it goes away, you should be thinking about a new belt. If nothing changes, check the power steering fluid, if its full, take to a mechanic

you can hear your power steering pump working and if it's whining, it may be low on fluid.
Check the fluid level with the engine running and be very careful of moving or rotating parts.
Locate the pump and check the level (the cap will usually have a dipstick to measure the level attached to the cap and you read it the same way as your engine oil dipstick). DO NOT overfill the pump as it will just leak out and cause other issues.
If the level is very low, top it up then work the steering from side to side a few times then recheck the level. Careful, power steering fluid can get very hot!!
If the fluid in the pump looks dark or black, take the vehicle to your local mechanic and have the fluid replaced and the system flushed.

Do you hear noises while turning the wheel at low speeds or stationary? If you hear a whining noise check the power steering fluid level. A low fluid level would make a whining noise as well as cause stiff steering. If you hear a squealing noise check the power steering belt tension. A slipping belt would cause stiff steering also. If you hear no abnormal noises check to make sure the power steering belt is there. If all of the above check out ok you may have a bad power steering pump, steering gear or a blockage in a pressure line.

Hi

Have you checked the power steering belt? it may be loose, sometimes when you turn the wheels the engine will move very slightly and cause the belt to squeel.

Get some wd-40 and spray the belt with the engine running then se if it gets any quieter.

It is quite common from a stand still, also check the power steering fluid.

Regards
Dan

A power steering pump will whine if it is low on fluid, when you turn the wheels you will hear the whine or if the power steering belt is to tight you will also hear the whine. You will not hear this whine when the truck is stopped.

It could be the fanbelt has snapped which drives the power steering pump and the alternater too, please check the belts.
