How Does Power Steering System Work??
Before discussing the different types of steering wheel noise, it’s important to understand how the steering system works.
The steering system helps drivers steer their vehicle by using a hydraulic pump to create pressure that assists in turning the car’s wheels. The engine powers the pump, and a belt or chain connects it to the crankshaft. When you turn the steering wheel, that motion is sent to the pump, creating pressure. That pressure is sent to a cylinder that contains fluid. The fluid moves through small tubes to the steering rack, which helps turn the wheels.
The steering system is important for drivers because it makes it easier to steer their car. It’s beneficial when you’re driving in a city where there are a lot of turns. It would be much harder to make these turns without the steering system. The steering system is also helpful when driving on the highway. It keeps the car going in the direction you want it to go and prevents it from veering off the road.
Causes of Various Types of Noise When Turning Steering Wheel While Stationary
Now that we know how the power steering system works, let’s discuss the different causes of various types of noise when turning the steering wheel while stationary:
- Low Tire Pressure
- Insufficient Power Steering Fluid
- Dry Jounce Bushing
- Worn Out Column Bearing
- Fluid Leakages
- Faulty Power Steering Rack
- Faulty Struts & Shocks
- Worn Out Power Steering Belt
- Steering Pump Malfunctioning
- Bad Tie Rod Ends
- Air Bubbles, Water, and Impurities in the Power Steering Fluid
- Faulty Ball Joints
- Hard Arm Control Bushing
- Clogged Power Steering Fluid Lines
Let us see these causes of noise when turning steering wheel while stationary in a bit of detail:
1. Low Tire Pressure:
If your tires are not inflated properly, it can cause the steering wheel to make a noise when you turn it. When the tire is under-inflated, it will bulge out at the bottom. This can create excessive wear on the ball joint and steering rack. It can also damage the sidewall of the tire, which can lead to a blowout.
Make sure to check your tire pressure regularly and inflate your tires to the recommended level. This will help keep the steering wheel noise from occurring.
If you have an inflator kit, make sure to use it to inflate your tires properly. These kits are easy to use and can be found at most automotive stores.
2. Insufficient Power Steering Fluid:
If there is not enough steering fluid in the system, it can cause the steering wheel to make noise when you turn it. The power steering system needs a certain amount of fluid to operate properly. If there is not enough fluid, the pump will have to work harder to create pressure. This can cause the steering wheel to make noise.
To ensure you have enough fluid in the system, check the power steering fluid level regularly. If it’s low, add more fluid to the system. Be sure to use the correct fluid type, as using the wrong type can damage the power steering system.
If your car has an automatic transmission, make sure to use Dexron III or Dexron VI steering fluid. If your car has a manual transmission, use Type F fluid.
You can find the correct type of fluid at most automotive stores.
If you’re not sure how to check the steering fluid level or add fluid to the system, consult your owner’s manual or take your car to a mechanic.
3. Dry Jounce Bushing:
If the jounce bushing is dry, it can cause the steering wheel to make noise when you turn it. The jounce bushing is a part of the suspension system. It helps absorb shocks and bumps when you drive over them.
If the jounce bushings are dry or if you have broken suspension bushings, they will not be able to absorb these shocks and bumps. This can cause the steering wheel to make a grinding noise when you turn it.
To keep the jounce bushings from drying out, make sure to lubricate them regularly. You can do this by using a spray lubricant or silicone grease. Lubing the jounce bushings will help keep them in good condition and prevent them from making noise.
4. Worn-Out Steering Column Bearing:
If the steering column bearing is worn out, it can cause the steering wheel to make noise when you turn it. The steering column bearing is part of the steering system. It helps support the weight of the steering wheel.
If the column bearing is worn out, it will not support the weight of the steering wheel. This can cause the steering wheels to make noise when you turn it.
To keep the steering column bearing from wearing out, make sure to lubricate it regularly. You can do this by using a spray lubricant or silicone grease. Lubing the steering column bearing will help keep it in good condition and prevent it from making loud rubbing noise.
5. Fluid Leakages:
Leaking steering fluid may cause noise when turning the steering wheel while stationary. This noise is often described as a humming, buzzing, or clunking noise. It may be constant or intermittent, and it usually worsens with speed.
There are a few things you can do to help reduce the noise caused by steering fluid leakage. Ensure the fluid is at the correct level, and add more if needed. You can also apply a sealant or lubricant to the power steering rack seals. If these measures do not work, you may need to replace the seals.
6. Faulty Power Steering Rack:
A faulty power steering rack can cause the steering wheel to make noise when you turn it. The power steering rack is responsible for supplying hydraulic fluid to the power steering system. If it is not working properly, it can cause the steering wheel to make noise.
It can also make it difficult to turn the wheel, particularly when the car is moving. If you experience either of these problems, it’s important to have the power steering rack replaced as soon as possible.
7. Faulty Struts & Shocks:
If your struts or shocks are faulty, it can cause the steering wheel to make noise when you turn the steering wheel. The struts and shocks help support the car’s weight and absorb bumps in the road. Additionally, if your vehicle is bouncing or swaying more than usual, it might be an indication that you need new struts or shocks.
Replacing your struts or shocks can be expensive, but it’s worth it in the long run. Not only will it make your car more comfortable to drive, but it’ll also help you stay safe on the road.
8. Worn Out Power Steering Belt:
If the power steering belt is worn out, it can cause the steering wheel to make noise when you turn it. This is because the belt cannot properly transmit the power from the engine to the steering wheel. To fix this, you will need to replace the power steering belt.
The power steering belt helps transfer power from the engine to the steering system. If it is not working properly, it can cause the steering wheel to make noise.
9. Steering Pump Malfunctioning:
A malfunctioning steering pump can cause the steering wheel to make noise when you turn it. A whining noise usually accompanies this. If you have a steering pump that’s not working properly, it will need to be replaced.
The steering pump is responsible for supplying hydraulic fluid to the power steering system. If it is not working properly, it can cause the steering wheel to make noise.
It can also make it difficult to turn the wheel, particularly when the car is moving. If you experience either of these problems, it’s important to have the steering pump replaced as soon as possible.
10. Bad Tie Rod Ends:
If the tie rod ends are bad, it can cause the steering wheel to make a whining sound when you turn control arms. The tie rod ends connect the steering system to the wheels. If they are not working properly, they can cause the steering wheel to make noise.
This is because the front tires are trying to move in two different directions simultaneously. When the car is stationary, the car’s weight is pushed down on the brake pads, which creates friction and heat.
The heat then causes the metal plates on the brake pads to expand, which pulls the brake pads away from the rotor. The caliper then pushes the brake pads back against the rotor, creating more friction and heat. This process can cause a lot of noise, especially if there is grease or dirt on the brake pads.
11. Air Bubbles, Water, and Impurities in the Power Steering Fluid
There are several possible noise causes when turning the steering wheel while stationary. Air bubbles, water, and impurities in the steering fluid can all cause a noise that can be annoying and difficult to diagnose.
Air bubbles can form in the steering fluid for various reasons. One common cause is air entering the system when the fluid is replaced. Another is when the system is overfilled, which can happen if the reservoir is not checked often or when the cap is not on tight. Air bubbles create noise as they pass through the narrow spaces in the steering gear.
Water can enter the system in several ways. One is when the system is overfilled, as mentioned earlier. Another is when the vehicle has been driven through deep water. Water can also enter the system if there is a leak in the hoses or seals. When water enters the system, it will mix with the steering fluid and create noise.
Impurities in the steering fluid can also cause noise. These impurities can come from several sources, including dust, dirt, and metal particles. When these impurities are present, they will create noise as they move around the fluid.
12. Faulty Ball Joints:
A ball joint is a type of joint that connects the steering knuckle to the lower control arm. This type of joint allows for a certain amount of movement in all directions. A faulty ball joint can cause noise when turning the steering wheel, especially when the vehicle is stationary.
13. Hard Arm Control Bushing:
The control arm is a metal bar that connects the steering knuckle to the car’s chassis. It is responsible for transmitting steering input to the wheel. The bushing is a rubber or plastic that sits between the control arm and the chassis.
It helps to reduce noise and vibration. A hard arm control bushing can cause noise when the steering wheel is turned.
14. Clogged Power Steering Fluid Lines:
The steering fluid lines carry hydraulic fluid from the pump to the steering gear. If these lines are clogged, it can cause noise when turning the steering wheel. This is because the hydraulic fluid will not flow freely through the lines.
If the fluid lines are blocked, the pump will have to work harder to send fluid to the steering gear, creating a whining noise. You can often fix this problem by flushing the system and refilling it with fresh fluid.
How can I Fix Power Steering Noise Problems?
You can do many things to fix power steering noise problems. The first step is to identify the cause of the noise. Once you know what is causing the noise, you can correct the problem.
- If the noise is coming from air bubbles in the steering fluid, one solution is to replace the fluid. Another is to overfill the reservoir. This will cause the air bubbles to rise to the top and escape from the system.
- If the noise is coming from water in the steering fluid, one solution is to replace the fluid. Another is to dry out the system by driving for a while with the heat on high. You can also try to locate and fix the source of the water leak.

Frequently Asked Questions
Can low power steering fluid cause grind noise?
Yes, low power steering fluid can cause grind noise. Low fluid levels can put excess stress on the power steering system, leading to component wear and eventually grinding noises. It’s essential to check your power steering fluid level regularly and top it up as needed to help prevent this from happening.
What can cause the power steering to be hard?
A few things can cause the power steering to be hard. One of the most common causes is low fluid levels. If the power steering fluid level is low, it can cause the pump to work harder and make the steering harder to steer.
Another common cause is dirty or contaminated fluid. If the fluid isn’t clean, it can cause the pump to work harder and make the steering harder to steer.
Finally, a worn power steering pump can also cause the power steering to be hard. If the pump is worn, it won’t produce as much pressure as it should, which will make the steering harder to steer.
Why does my power steering only work when I accelerate?
There are a few potential causes of this issue. One possibility is air in the system, which a leaky hose or seal can cause. When the power steering pump starts, it draws in the air and the fluid, which can cause the steering to feel stiffer when you’re not accelerating.
Another possibility is that there is dirt or debris in the system, which can also cause the steering to feel stiffer. If you’ve recently had your power steering fluid replaced, it’s possible that the new fluid isn’t compatible with the old fluid, which can also cause problems.
