What you hae to do is check if the reservoir is leaking first if okthen it is either the piping or the steering pump. It is a process of elimination, you may need to clean the area first to discover where the leak is or work back from the point it is leaking on the belt. Until you identify where the leak is coming from it will be dificult to repair unless you just start to replace the pump and reservoir any way.

The power steering pump shaft may have broken inside the pump. I have seen this happen on a these trucks. Have your pump checked.

SOURCE: whining when i press gas

normally, the only part of your automatic transmission that will make a whining noise is the pump. it usually whines when iether the fluid is low or more commonly when the transmission oil filter is getting plugged up.

the power steering pump will also make a whining noise too.

turn the wheel all the way to the right and hold steady pressure against the stop. this puts maximum force on the power steering pump and, if the power steering pump is the one making the whine, it will change the sound of it. (usually louder).

if the trans pump is making the whine noise, it should sound different in neutral compared to drive. this test will really only work if it make the noise without the vehicle moving. if it wont do it at idle hold the rpms at 2000 or so.

if you decide the noise is coming from the transmission, and the transmission filter has not been replaced (assuming you installed a used transmission), replace the filter by removing the oil pan.



oh and also, if it is the power steering pump you should be able to make it make the whining noise while the vehicle is stationary. if it wont make noise unless its moving its not the power steering pump.

Power steering whining, sqreeching


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!

There is a loud "whining"


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

2004 F150 2X4 crew cab The steering was hard then works fine now its back to hard again have no idea where to look the fluid is full. The pump whines when it dosent work some time just at a lost would...


It sounds very much like your power steering pump is going out. It was very good to check the fluid, something else that you may want to check is the tension on the belt that is turning the power steering pump. In few cases a worn belt can lose it's grip on the pully, especially if it's cold outside. Also, sometimes the tension pully is bad and isn't able to keep the belt tight enough to get a good grip on the pully.
If you are sure the whining is comming from the power steering pump, you will most likely have to replace it.

I hope this helps you.

While turning the steering wheel there is a whining sound from the motor. What is it?


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.

Whining Noise


Hi, this sound is most likely coming from the power steering pump. I would first, check the power steering fluid level to see if it is full. if its not at the full mark, add some fluid. If the fluid reservoir is full upon inspection and the whining continues, the pump may be damaged and the pulley on the power steering pump could be slightly out of sync with the pump housing.

The second issue could be belt slippage. i would do a tension check on the drive belt and pulleys as well. make sure there isn't any ware and tare on the belt and make sure the tension is to specs.

Please rate and god bless:)
