Usually this is caused by a leak. A worn out power steering belt can cause a squealing noise because the belt can slip when the wheel is turned. A failing power steering pump can also be the cause of a squealing noise because the system isn`t maintaining the proper fluid pressure.
Trapped Air In The Power Steering Fluid Or Pump It`s possible the whining noise is simply coming from trapped air bubbles in your power steering fluid. If you suspect this is the case, you can confirm it by removing the cap from the power steering fluid reservoir and checking if any bubbles or froth has formed in it.
Low Power Steering Fluid: If you hear a squealing noise while turning the steering wheel, it may be an indication that the power steering fluid is low. Fluid may become low because of a leak. You can check under the engine for leaks by looking for red or pink liquid, the typical color of most power steering fluids.
When the diaphragm fails it can cause an excessive vacuum on the engine. This vacuum causes a squealing sound as air goes throughs the system. Removing either the vehicles dipstick or the engine oil cap will cause the squealing the noise to stop. When the system is resealed, the squealing noise will reappear.
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.
Your car`s tie-rod ends, seals, ball joints and universal joints all need lubrication, and if they dry out, that could lead to a squeal, screeching or similar noise; you may even hear a grinding noise. Again, a technician or mechanic should be able to identify the problem and recommend a repair.
High-Pitched Squeal
A loose or worn fan belt, also known as the serpentine belt, is usually the cause. Replacing this belt or belt pulley should eliminate the sound. Consider having the timing belt checked as well.
Suppose you notice your car has started making a squeaking sound when you turn. In that case, there are three common culprits: a lack of lubrication in the suspension, low power-steering fluid, or friction between the steering wheel housing and the interior trim.
If lubrication is the main cause of squeaking it can be an easy and inexpensive fix to take on a DIY project with a grease gun and some spray-on lubricant; or even easier, take your vehicle to an express oil change and preventative maintenance supplier like Jiffy Lube of Southern California.
Common reasons for this to happen:
Failing Water Pump Pulley: The most common cause of squealing or squeaking from the timing belt cover is the water pump pulley. If the bearings in the pulley are beginning to fail, they will make noise.
Most of the time, this type of noise is associated with a problem with the pump`s power steering fluid. In some cases, it may not have enough fluid to operate noiselessly. Check the fluid reservoir (usually located near the top of the pump) to make sure it`s filled to the indicator line.
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.
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.
The power steering pump`s maximum pressure should be set at a minimum of 200 psi above the system operating pressures. For example, if the system`s requirements are a 1000 psi, then the pump`s maximum pressure should be set at 1200 psi or above.
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.
A high-pitched sound is shrill and high in pitch.
The brake pads are prone to wear and tear, become thinner over time, and make squeaky noises. As it`s a bad idea to drive with a squeaky break since it can lead to brake failure, the optimal solution is to drive to the nearest auto shop and have your brakes inspected by a qualified mechanic.
You can continue to drive safely for up to 2 weeks with a squeaky belt. However, it`s best to not delay too long and replace it as early as possible.
If your vehicle is making a squealing sound when the steering wheel is being turned, start by checking the power-steering fluid level and replacing or adding the fluid as necessary — and if that doesn`t eliminate the noise, make an appointment with a service technician to find out if something else is going on.
The most common reasons a Volvo S60 engine makes a ticking noise are low oil level or pressure, an issue with the ignition system, or an exhaust leak.

How Long Should My Power Steering Pump Last? A. There`s no set expiration date for your power steering pump. That said, you should count on having to replace the pump after 100,000 miles or so.
