Making noise when the steering wheel is turned. Low vibration also when it's making he noise. If I do need to add steering fluid, what specifications should I look for?

I hope you are using the right PS fluid for your vehicle! Have you checked that?

Power steering systems are tricky. Whenever you add fluid, you should (with the engine running and PS pump turning), turn the wheels ALL the way, both left and right while creeping as slow as a snail on an open parking lot ... at least twice (like R-I-G-H-T, then L-E-F-T, then R-I-G-H-T, then L-E-F-T)! Then re-check the PS fluid level again, and if still low, repeat the whole process! DON'T turn the steering wheel too fast!

could be one of the other pulleys making a similar noise. most commonly the alternator. easiest to figure out with vehicle running use stethoscope to determine which pully on serp belt making noise

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!

Does your car make a groaning noise when you turn the wheel? It could be a few different things. The first thing you want to do is check your power steering fluid. If it's low, top it off and see if that helped. It just takes a standard power steering fluid, nothing specific.

If the power steering fluid was low and that fixed the problem, you need to ask yourself the question - Why was the fluid low? There's probably a leak somewhere that needs to be fixed.

If the power steering fluid wasn't low, then there's a couple other things it could be. If the car makes a groaning noise when you turn the wheel, chances are that you have a bad power steering pump. If there's no noise and you just don't have any power steering at all then it could be a bad pump or a bad power steering rack.

Hopefully this helps you figure it out. Good Luck!

The squealing noise when turning the steering wheel happens in most cases when the power steering fluind is low. Check to see if there is power steering fluid in the reevoir. If not add fluid to the proper level and the squealing should stop. Good luck

power steering fliud is leaking,cud b rhe power steering pump or the steering rack needs to be checked.

YOU NEED TO BLEED POWER STEERING SYSTEM BY HAVING LOW FLUID AIR ENTER THE SYSTEM.PARK CAR ON SOLID LEVEL GROUND SAFELY RAISE SUPPORT VECHICLE ON JACK STANDS.YOU CAN LEAVE CAR ON GROUND BUT TURNING STEERING WHEELS BACK AND FORTH WILL WEAR SPOT IN TIRES.TURN STEERING WHEEL TO THE LEFT WITH THE ENGINE OFF.CHECK POWER STEERING FLUID.ADD MORE FLUID IF LOW.MAKE SURE FLUID LEVEL ON COLD MARK ON DIP STICK.THE YOU CRANK CAR UP LET IDLE LITTLE HIGH FOR 15 SECONDS.THEN TURN OFF ENGINE.CHECK POWER STEERING FLUID LEVEL MAKE SURE ITS ON COLD MARK AT DIP STICK.THEN YOU START THE CAR UP WHILE IDLING TURN STEERING WHEEL IN BOTH DIRECTIONS SLOWLY TO THE STOPS DONT HOLD IN STOP TURN STEERING WHEEL LEFT AND RIGHT FOR SEVERAL TURNS.STOP ENGINE CHECK FLUID IF FLUID TAN STILL HAS AIR IN SYSTEM.LET CAR SET A LITTLE WHILE TRY THE BLEEDING PROCEDURE AGAIN.THERE IS A REASON POWER STEERING FLUID WAS LOW CHECK ALL POWER STEERING HOSES AT POWER STEERING PUMP TO THE RACK PINION ASSEMBLY.

yes power steering is most likely very low , repair leak , as the fluid is flameable

drain power stearing fluid and refill with mercon automatic transmission fluid and add motorcraft xl - 3 friction modifier.

if still the problem persist, you mau have to chnge steering gear
