Power steering pump whining and leaking
The power steering pump in my car is whining and is using fluid, though it is not leaking on the ground. In addition, the car is hard to steer and is smoking.
Experienced mechanics share their insights in answering this question :
Hello. If the system is losing fluid then there must be a leak somewhere. Most of the time the leak is at the rack and pinion so it tends to leak further back on the vehicle. If the pump only whines when it is low then that is common. If it whines when it is full also then it may need to be replaced. If the leak cannot be found I typically add dye to the fluid and allow it to identify where the leak it when using a UV light. If you need to have this inspected, consider YourMechanic, as a certified mechanic can come to your home or office to find the leak and repair the problem.

If you notice a squealing or whining noise whenever the wheels turn, there is a strong possibility that it is due to low power steering fluid. The power steering system uses a pump so the fluid can flow for smooth steering.
Causes of a Power Steering Fluid Leak
Worn seal on power steering pump. Cracked, perished or loose power steering fluid hose. Excessive pressure in power steering system caused by an overfilled reservoir, which could result in blown seals. Wear and tear in power steering rack, particularly the shaft ends and seals.
If there is a lack of fluid in your power steering system the fluid reservoir will get low. Your power steering pump draws fluid in from that reservoir and if there is a low fluid level it can also draw air in along with it causing the same bubbles and whining sound.
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.
Age and constant usage are the two biggest contributing factors to a power steering fluid leak. As the supply and pressure hoses start to age, they may develop holes through which the fluid can leak. Likewise, the O-rings and seals gradually lose their flexibility as your mileage increases.
If your car makes a whining noise when you turn the wheel, there may be a leak in the power steering pump. Or, the power steering fluid level may be low. Power steering making noise is something all motorists want to avoid.
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 there is air entrained in the power steering pump fluid, it can cause the pump to whine while it is running.
Power steering fluid is as vital to safe driving as oil is to continued engine prowess. Without this vital fluid, your power steering will fail. For example, if you have a power steering leak, you may not be able to turn the car with the force needed. This can lead to unsafe driving situations and a potential accident.
Product Description
STP® Power Steering Fluid + Stop Leak is scientifically engineered to reduce fluid loss caused by seals that leak due to wear or shrinkage.
Faulty power steering pumps often cause fluid to leak between the reservoir and the pump itself. However, remember that not all leaks can be associated with a faulty power steering pump. That`s why a thorough inspection should be done to determine the issue.
Additives in power steering stop leak fluids work to remove debris, neutralize acidity, and fill leaks. However, they are not a permanent solution to fixing a leak in your power steering. Over time, a leak can start again, and you`ll have to add the fluid again.
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.
Leaks commonly occur at junctions where a rubber hose transitions to a hard line or where a hard line screws into the rack or pump. If you find a leak at a connection, you can have your mechanic tighten the connection; if you have a soft hose that`s leaking, it`s best to replace that hose.
How long does it take to start working? Bar`s Leaks starts working the minute you install and start driving the vehicle. You will usually see results in about 200 miles or three (3) days of driving.
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.
One of the main symptoms the power steering hose is going bad or is failing is the steering wheel becomes difficult to turn. If there is not enough pressure in the system to get the power steering fluid to the rack, the vehicle will be difficult to turn or make maneuvers that would normally be no problem.
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.
While the transmission is the most likely cause, whining while accelerating can also be caused by low power steering fluid or more serious damage like faulty alternator bearings, a malfunctioning water pump, a broken piston or a bad AC compressor.
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.
BlueDevil Power Steering Stop Leak permanently seals leaks in power steering, differentials, and worn rack and pinion systems. It`s safe and easy to use and guaranteed to work to stop leaks. BlueDevil Power Steering Stop Leak works on gasoline or diesel engines.
Red Fluid. There are two fluids used by your vehicle that are red. These are the automatic transmission fluid and the power steering. Both of these are hydraulic fluids.

had power steering pump replaced but power steering fluid is leaking
ANSWER : This suggests that you may have a leak somewhere else in your power steering system such as one of the hoses or the rack and pinion system. As you may know, the power steering system is a highly pressurized system that can have as much as 300+psi of pressure in the system at times, so it is not uncommon for these types of leaks to happen. If you’d like to get this fixed, I would recommend having an expert from YourMechanic come to your location to diagnose the leak in your power steering system and make the the necessary repairs to fix it.

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.

Steering Issues
ANSWER : Hi there:
In most cases, when you notice a power steering fluid leak, it’s caused by a pinched or slightly damaged power steering hose or the fittings have cracked. The problem can also be caused by a power steering pump gasket or seal that has worn out and needs to be replaced. Without knowing specifics about your vehicle, it’s hard to give you exact replacement advice, so i’d recommend contacting a mobile mechanic to complete a power steering system inspection; so they can determine what’s causing the leak and recommend the right repairs.

The power steering pump seal keeps breaking when pump is replaced.
ANSWER : There may be a restriction in the power steering high pressure line causing an excessively high amount of pressure in the line and the pump. If the belt tensioner for the power steering belt is a manual tensioner that can be adjusted, the tension may be too tight causing a high load on the bearings at the power steering pump drive shaft. You can try having the power steering system flushed to see if this will clear any blockages and be sure to use an OEM quality power steering pump as some aftermarket components are not manufactured as well as the originals. Consider hiring an experienced technician like one from YourMechanic who can come out for a closer inspection of the vehicle in order to offer a more personal diagnosis if your power steering concerns.

leaky power steering pump, steering wheel will not turn
ANSWER : Hello. It could be possible that the steering gear or power steering pump have seized and are no longer functioning. In most cases of pump failure, the steering will still turn, however it will require increased effort due to the lack of powered assistance from the power steering system. If the steering wheel is now stuck, that could indicate the potential of a problem such as damage to the steering gear or linkage components. If the pump is leaking, I would start by addressing that first, as it will likely continue to leak until all of the fluid has been expelled, and may even be what is causing your steering wheel to get stuck. A professional technician, such as one from YourMechanic, can visit your location to replace your power steering pump.

Chrysler 3.8 L. T&C power steering rack and pump replacement.
ANSWER : As you may know, the power steering rack pumps power steering fluid through a series of small reed valves that help to produce hydraulic pressure as the system is pressurized by the pump. This is what allows the power steering system to assist you in steering your car. When either the pump or the rack is not working properly, one or the other can sometimes over compensate for the other to a certain degree, but will eventually be overworked and fail. It sounds like this may have been the case in your situation. I would suggest having a second opinion on the previous mechanic’s work. If you’d like a professional from YourMechanic can come to your home or place of business to properly diagnose and repair your power steering system.
