Maintain steady pressure while steering with premium power steering pump. It keeps your car's power steering in top shape for better safety and drivability.
If your vehicle's power steering feature unexpectedly stops working, it might be because of steering pump failure. Your vehicle's power steering pump may be causing a loss or decrease in hydraulic pressure. To be sure, you should seek the assistance of an auto mechanic. When you ignore a problem concerning the power steering pump, you might find yourself struggling just to steer your vehicle.
Operated by the engine belt, the power steering pump uses hydraulic pressure to help you control your vehicle's movement more easily. This pump is equipped with a set of rotating vanes designed to draw hydraulic fluid from a return line. As you turn your vehicle's steering wheel, valves regulate the flow of hydraulic fluid from the steering pump to the steering axis. This process increases the steering axis' torque, in turn decreasing the effort needed to turn your vehicle's wheels.
Your vehicle's power steering pump usually contains a valve that relieves pressure build-up in case of high engine speeds. But of course, this valve is not enough to prevent steering pump failure. Buzzing or whining noises coming from under the hood are typical symptoms of a faulty steering pump. Once your mechanic diagnoses that you need to replace your vehicle's steering pump, don't look anywhere else. You can get the best power steering pump replacement here from us.

The power steering pump is the heart of many power steering systems that don’t rely on electric motors. A functioning pump makes it much easier to control your vehicle on the road. If the pump gives out, you must replace it as soon as possible to prevent damage to the rest of the steering system.
What is a power steering pump?
The power steering pump is a machine that converts the energy generated by the vehicle’s internal combustion engine into hydraulic power. It delivers that power to the steering system, where it bolsters the torque produced by the driver turning the steering wheel.
The pump connects to the engine through a drive belt. When the engine runs, the belt transmits the energy to a rotary in the power steering pump.
As the rotary spins, it forces power steering fluid to travel through the pump. The pumped liquid gets injected back into the power steering system under high pressure.
This hydraulic pressure applies force on the rack and pinion steering column. The steering column connects the steering wheel with the rest of the steering system.
Turning the steering wheel adjusts the hydraulic pressure applied to the steering column by the power steering pump. When the wheel is at rest, the pressure on either side of the column stays even.
When you turn the steering wheel in one direction, the pressure in the matching side of the steering column increases. The rising pressure forces the column to turn that way.
How does power steering make driving easier?
Power steering reduces the physical exertion required to turn steering wheels and the vehicles they control. Drivers can get even the biggest, heaviest vehicles to make sharp turns with ease instead of having to wrestle with the wheel in cars with manual steering.
The power steering pump makes this convenience possible. As the heart of a power steering system, it generates the hydraulic pressure that makes it possible for the system to help move the steering wheel.
Symptoms of a bad or failing power steering pump
Common symptoms of a bad or failing power steering pump include:
Stiffness in the steering wheel
A power steering system makes it easier to turn the steering wheel. When the power steering pump fails, the system stops working. The wheel becomes stiff and harder to move than usual, forcing drivers to put more effort into turning them.
This stiffness becomes very apparent when you are driving slowly or have brought the vehicle to a stop. During those times, the pump puts in extra effort.
Wheels respond slower to the steering wheel
The steering wheel can kee[ its responsiveness despite the lack of sufficient hydraulic pressure from the faltering power steering pump. Instead, the wheels themselves can respond more sluggishly to the steering’s input.
The slower response time can also come with whining noises. If you encounter these two symptoms together, check your vehicle’s power steering pump.
Vibrations in the steering wheel
An operational power steering pump vibrates. While the vibrations can reach the steering wheel, they lack the strength to catch the driver’s notice.
However, a broken or worn pump produces greater amounts of vibration that can become noticeable and uncomfortable. If the steering wheel vibrates while the engine runs idle, check the power steering pump’s moving parts or the drive belt that runs it.
When you start your car’s engine, you may hear squealing noises from the vehicle’s hood for the first minute. The sound comes from the belt that runs the power steering pump. A worn or broken rotary can cause the belt to slip and squeal.
If the power steering system runs low on hydraulic fluid, it will issue whining sounds at every turn the vehicle takes. Refilling the power steering pump’s reservoir usually fixes the problem.
However, if you keep hearing the noises after replenishing the hydraulic fluid reservoir, the pump likely developed a leak. It’s possible to patch the leak, but you may need to replace the entire pump.
If you hear the power steering pump groan, you must replace it as soon as possible. Groaning noises warn that the pump has completely broken down and cannot deliver enough pressurized hydraulic fluid to where it’s needed. If you ignore the noises, the problems will spread to the rest of the power steering system.
Picking a power steering pump replacement
Power steering pumps come in three primary types:
- Vane pumps store the power steering fluid in their housing. When the hydraulic pressure builds up, the fluid exits the pump and goes to the steering gear. They are the most common type found in vehicles
- Roller pumps draw the power steering fluid while the latter undergoes pressurization and before the fluid leaves through the outlets. They use centrifugal force.
- Slipper pumps apply hydraulic pressure and release fluid with the help of springs.
The owner’s manual can tell you about the type of power steering pump in your vehicle. Try to get the same type or even the same model as the old pump.
Additionally, shops like CarParts.com have filter bars. If you enter the year, make, and model, you can quickly identify a power steering pump guaranteed to fit your vehicle.
No matter the type, get a pressure-resistant replacement. The new pump must withstand the considerable pressures needed to move power steering fluid.
Power steering pump cost
Manufacturers intend the factory-issue power steering pumps to last as long as the vehicle. But the component can fail or break down earlier than expected.
The cost of a replacement power steering pump on CarParts.com can range anywhere between $18 and $1,338. Various factors affect the prices. New pumps cost more than remanufactured units, while branded names likewise have higher price tags. Some pumps come with additional components like pulleys and hydraulic fluid reservoirs. You can purchase individual pumps, sets of 2 with the second serving as a spare, and power steering pump kits with power steering or pressure hoses.

How to Choose the Right Power Steering Pump
A power steering mechanism allows you to steer your vehicle more easily to your desired direction. With this mechanism, you can effortlessly steer and control your vehicle regardless of the road condition. Minimal effort is required when driving, so your energy is saved while you enjoy quicker steering response and
road feel. Most power steering mechanisms are hydraulically powered, so you need a good power steering pump to push a sufficient amount of fluid into your steering gear box. This high-pressure fluid is required to turn your vehicle's wheels. Without it, the hydraulic power steering mechanism is useless.
What should you look for in a power steering pump?
A pressure-resistant power steering pump is highly recommended, as it requires a great amount of pressure to force the fluid out into the gear box. You also have to consider the design of the pump's fins to determine if it can move the steering fluid inside efficiently. All pumps contain a spinning rotor inside the housing, but you have to check if this rotor is made of durable materials first, as it could easily break down when subjected to extreme pressure.
There are three types of power steering pumps: vane, roller, and slipper. Among the three, vane is the most commonly used type. Vanes trap the power steering fluid before subsequent pressure increase forces the fluid out of the housing. Rollers use centrifugal force to trap the pressurized fluid before it is pushed out through the pump's outlets. The slipper type, on the other hand, needs the assistance of springs to pressurize and release the fluid.
These types may or may not work well with your vehicle's power steering system. Check your owner's manual first to know which type fits your car's OEM requirements.
How much will a power steering pump replacement cost?
Power steering pumps generally cost around $80 to $150. Second-hand, reconditioned pumps are a lot cheaper, but don't get one unless you're working on a really, really tight budget. You can't expect these pre-owned pumps to work better than your old one, so don't waste your money on them. Add around $100 to $150 on top of the pump cost if a mechanic will do the replacement for you. If you're planning to take your vehicle to a dealer for pump installation, then labor cost will skyrocket to around $200 to $225. To save more money, it will be better if you'll just purchase a replacement and do the installation yourself.
