Experienced mechanics share their insights in answering this question :
Your power steering pump may be leaking and will whine when it is low on fluid. You should locate the leak in the system before you condemn the power steering pump. You may have a leaking steering gear or power steering pressure or return hose. Once you locate the leaking component it should be replaced and the rest of the system rechecked for leaks. The best way to find a leak is to clean the entire system with soapy water to remove oil leak evidence. Add oil leak dye to the power steering pump and run the vehicle and drive it on a road test to operate the system and then recheck for the leak using the dye leak detector to locate leak or leaks in the system.

You will need to flush the power steering fluid in order to get rid of the pesky air pockets if you find this is the cause of the noise. However, to avoid any more air getting trapped in the fresh fluid, ensure you check all the connections from the reservoir to the pump, tightening any loose ones.
Trapped air and pump design
If the pump impeller starts to catch air bubbles, it can cause unwanted noise and vibrations. It can be difficult to diagnose air bubbles trapped inside the pump. We recommend a power steering fluid flush to drain the fluid and get rid of any air bubbles.
A low fluid level is the most common cause of power steering noises. The power steering fluid reservoir is small and many people don`t think to check it very often, so it won`t take much fluid loss to cause a problem.
One of the most common problems power steering systems have is leaks. The high pressure of the system combined with the soft hoses carrying the fluid makes it relatively susceptible to leaks. A low fluid level can cause a whining power steering pump and even a loss of fluid pressure and a loss of steering assistance.
There are six main causes of bad power steering pump symptoms: lack of fluid, dirty fluid, obstruction in the system, seized pump, low pressure, and high pressure.
While pumps are quite durable, they can and will eventually wear out. Too much strain on a pump can cause them to fail prematurely (i.e. strain from being pushed to operational limits like turning your steering wheel all the way to the right or left).
If the power steering pump pulley starts to fail or intermittently binds, you might notice that your car`s steering will either not respond well when you turn the wheel, or it will respond excessively. When the pulley binds for longer periods of time, you may notice a burnt smell under the hood of the car.
A sure sign of air in the system is what sounds like a mildly disgruntled cat under the hood. This growling will get louder during power steering-intensive movements such as parallel parking. The first thing to check when the power steering starts moaning and groaning is the fluid level.
If air does find its way inside of the power steering assembly, you may hear a growling noise when you drive and the steering wheel may be slightly harder to turn than it normally is. Bleeding the power steering is a simple way to force trapped air out of your power steering pump and hydraulic lines.
Failing Power Steering Pump: If your power steering pump is beginning to die, it could very easily cause these symptoms. As the pump fails, it produces less and less pressure for the power steering system, causing vibrations, shudders, whining noises and more.
Vehicles that are designed with a power steering pump should only be used when the power steering is operational. When the power steering stops working, you should refrain from operating the vehicle until the pump is replaced.
You can drive with a bad power steering pump, but it`s not recommended. The pump is responsible for transmitting power to the steering wheel, so if it`s not working properly, you won`t be able to steer the car. In some cases, you may even experience difficulty braking the car.

Power steering fluid groaning noise. Power steering leak?
ANSWER : Hello. A groaning noise is an indication of low power steering fluid. If you had your power steering fluid serviced about 5 months ago and it is making a groaning noise again most likely means your power steering pump has gone bad or your power steering leak has going from minor to moderate. I can tell you that Honda Accords are one of the most common vehicles for a power steering pump leak to occur on and require a pump replacement. If not a leaking pump it could be power steering hose leaking fluid. I suggest that you have a power steering fluid leak inspection done otherwise you will have to keep filling up your power steering reservoir until it is fixed.

My engine whines. It was low on power steering fluid, but adding did not make it goes away. Does it sometimes take a few minutes 2000 Mercury Villager
ANSWER : Hi there – your whining noise is probably due to air still being in the steering system, which can be removed by turning the steering all the way to the right, then to the left – repeat a couple of times, then re-check the steering fluid level, and add more fluid if necessary. Given your mileage, you may need to flush the steering fluid and replace the filter, which is in the bottom of the fluid reservoir. If it is clogged, the pump can’t get fluid fast enough, and will whine as though the fluid were low. I recommend a steering fluid service performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location and perform this maintenance service.
grinding noise while turning right or driving straight
ANSWER : Hello. If the noise is still there when the engine is off and if you are not turning the wheel, then it is typically either a failing bearing in the rear differential or it can be a failure in the transfer case if it is four wheel drive.
The transfer case is a very common failure on this vehicle. If it is two wheel drive then I typically start by draining the oil from the rear differential and inspecting the fluid for metal.
Any metal in the fluid indicates a bearing failure. If that is also fine, then it may be an issue within the transmission. It may be a failure in one of the thrust bearings. If you need to get this looked at, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose your car’s grinding noise.
power steering fluid is leaking
ANSWER : With a power steering fluid leak that big, you certainly should have the vehicle inspected as soon as possible to find the exact cause. Any of the components you listed can be the source of the leak. The power steering pump as well as the rack & pinion steering unit rely on the fluid for lubrication as well as cooling. The whining you hear is from the pump when the fluid runs low or empty. Your issue can be caused by something as simple as a fluid hose right now, but continued ’running dry" of the power steering fluid, can result in damage to both the pump and the rack & pinion unit. If that happens, you can take what may be a repair of a few hundred dollars and turn it into a repair of a couple of thousand dollars.
Power steering is making noises seems like is looking power does the power steering pump makes the car to automatically stops lock
ANSWER : Noises from the power steering system can be due to low fluid level, as well as a loose drive belt, so be sure to check those two possibilities first. If there is still no resolution, that is if the noise problems persist, you should request a steering noise diagnostic. If faults with the power steering pump are causing the engine to loose power, then you should mention those issues to the mechanic when he does the noise diagnostic so that the mechanic can evaluate the freeness of the pump pulley and look for other faults. If, though, the engine is losing power, due to other causes such as ignition or fuel system faults, those will have to be separately diagnosed.
Car making whining noise and leaking power steering fluid.
ANSWER : A whining noise while turning the wheel could certainly be caused by low power steering fluid. Air being sucked through the power steering pump is what causes the whining noise. I would suggest that you ask for help from a mechanic to check for your power steering fluid leak so your power steering won’t whine anymore.
power steering problem.
ANSWER : Hello. Noise could be a sign of trapped air, low fluid level, or a mechanical fault in the pump. While the system is cold, check the fluid level. If the fluid level is OK, remove the cap and turn the steering wheel left and right to full extent while it is on. If there is air in the system, that will help purge it. Replace the cap. If the noise remains, it needs to be determined if it is coming from the pump or another accessory, pulley, or belt. YourMechanic has experts in this type of power steering diagnosis and once the fault is found, they will let you know of the cost to repair.
