Quite often, you may find it hard to turn the wheels or notice noise when turning the steering wheel while stationary. The difficulty indicates a deeper problem with your engine, suspension, or steering system.
Turning the steering wheel also needs ample power steering lubrication. Therefore, you can temporarily fix the problem by lubricating your vehicle and not risk wearing its critical components.
However, if you don’t get a mechanic to fix the repair, or replace the faulty parts immediately, you risk causing accidents to you and other road users.
You and your mechanic can identify the faulty parts by the kind of noise you hear when turning the steering.
You may hear a whining, grinding, clunking, chucking, or squeaking noise, depending on the fault of your engine, suspension, brakes, or steering system.
This article explores the technical causes of hurdles and noises when turning the steering of a stationary vehicle.
How Does Steering Work?
Before we can explore the causes of noise when turning the steering wheel, it’s important to understand how steering works. The steering wheel is connected to the front wheels of your car via a series of gears and linkages.
When you turn the wheel, it spins these gears, which in turn rotate the front wheels.
This system allows drivers to steer their cars in any direction they want, by rotating the wheel left or right. It also helps power the car forward or backward, depending on which way the front wheels are pointing.
Types of Sound Your Steering Wheel Can Make During Turns
Your car’s steering wheel can make a variety of sounds besides rubbing noises if the steering or suspension system is faulty.
It can create whining, popping, clicking or screeching noises during turns on the road. Let’s see what each type of sound means!
- Whining- This kind of noise happens if there is an issue with the steering pump.
- Popping- This noise indicates that the suspension system is either damaged or worn out.
- Humming- This kind of noise means that the car’s weight distribution is uneven.
- Rubbing- This kind of noise is created when there is a problem with the upper bearing of the system.
Knocking And Clunking Noise When Turning: What Are The Culprits
#1. Bad tie rods.
Tie rods play a key part in the system, they connect the steering arm to a vehicle’s steering rack. By doing this, tie rods will connect the tire direction with the turning of the steering wheel, which helps drivers to control their cars.
However, when a tie rod end is loose or worn, car owners can notice immediately a clunking noise.
More than that, worn tie rod ends also make turning more vague, and creaking noise when turning the steering wheel. So if a car makes noise when turning, tie rods are the part drivers need to check.
#2. Bad sway bar link.
Unlike tie rods, anti-roll bar, or sway bar link takes responsibility for reducing body roll while turning or cornering. It also helps keep the four-wheel vehicle stabilized on the road, and avoid rolling over when having a sharp turn.
However, if your car makes noise when turning, especially a clunking sound, the sway bar could have broken or damaged. And it needs to be fixed soon. Not only the knocking noise when turning the steering wheel, your vehicle will also have difficulty handling.
#3. Bad ball joints.
Last but not least, ball joints are the parts connecting the wheel hubs to the rest of the suspension components.
For that reason, if a ball joint goes bad or fails, you may notice a creaking noise when turning the steering wheel, which will be louder over time.
Depending on different cars, a few ball joints per wheel may not be load-bearing. So if your car makes noise when turning, check the bad ball joints now.
Suspension and Steering Components
Issues with your car’s suspension and steering components can also result in strange noises:
- Worn ball joints or bushings: Worn-out ball joints or bushings can cause clunking or knocking sounds during turns. Have these components inspected and replaced if necessary.
- Loose or damaged tie rod ends: Tie rod ends connect your steering system to the wheels. Loose or damaged tie rod ends can create clicking or popping noises as well as a rattle over bumps. They may need to be replaced.
- Seized strut bushings: The upper mount on front struts can get dirty or corroded. It can make steering motions feel inconsistent as well as cause popping or crunching noises.
- Damaged CV joints: If one of the axle shafts has a torn CV boot that’s allowed dirt inside, it can bind and make noises when you’re turning. It’s typically a popping noise.
Causes of the Noise When Turning the Steering Wheel While Stationary
#1. Insufficient Power Steering Fluid.
Low power steering fluid is one of the main causes of a whining noise when turning steering wheels when stationary.
Most cars using a rack and pinion steering systems comprise the circular steering that is connected to the gearbox through a metal rack.
This rack also has a tie rod to help turn the circular motion of the steering to linear motion and reduce the gear impact for the wheels to smoothly turn.
For the system to work seamlessly, it receives high-pressure fluid lubrication through two ports on the piston’s sides. Not only does the fluid lubricate the gears and column, but it provides great power for the piston to move.
#2. Poor Fluid Quality.
In addition to whining, you may a sharp grinding when turning the steering wheel of a stagnant car. This symptom indicates that you use the wrong lubrication fluid.
Nowadays, most vehicle manufacturers design vehicles that can only use specific lubrication according to the unique minerals ideal for lubricating the parts’ chemical compositions.
Examples of lubricants preferred by common manufacturers are Pentosin, Dextron, and P/S fluid. Using the wrong power steering lubrication causes damage to the entire power steering system.
#3. Fluid Leakages.
Leaking steering pumps is also a common cause of annoying noises when operating your vehicle.
The magnitude of the leaking power steering fluid will determine the extent of the whining, grinding, or clunking noise when turning the steering wheel while stationary in your car.
Similar to the cases above, the low lubrication capability wears the power steering belt bringing about severe difficulties in turning the steering column, metal rack, and gears.
You can identify power steering leaks through the stains at the bottom of your parked car. However, the fluid stains might also be from engine oil or brake fluids.
Therefore, check the steering fluid reservoir levels to rule out other automotive fluid leaks before you call your garage.
#4. Faulty Steering Rack.
Sometimes clunking sound when turning the steering wheel can mean you have a more severe problem than low steering fluid or a leaking steering system.
You can have a faulty steering rack after getting into an accident or because you have not serviced your vehicle for a while.
The clunking sound from a faulty rack usually knocks in pauses when you turn the tires from one end to the other. Repeated clunks indicate mounting or bad struts.
#5. Faulty Struts.
Whenever your car has suspension problems, it becomes very difficult to steer especially at low speeds or when stationary. The steering system relies on the vehicle suspension to turn its wheels.
Therefore, faulty struts and improper suspension cause strain to the steering system which could cause detrimental damage to its mechanics.
When your car makes noise when turning right but not left it indicates that you have failing ball joints and the tie rod end has worn out. The clunking sound is due to sudden weight shifts of the car as its tires turn.
#6. Worn Out Power Steering Belt.
When you have a broken or worn-out power steering belt, your car is likely to produce a sharp screeching or squeaking noise when turning the steering wheel left or right during low speeds or in a stationary position.
This belt is the connection between the engine and the power steering pump. It, therefore, requires enough lubrication from the power steering fluid to prevent it from wear and tear during your vehicle’s operation.
#7. Air Bubbles, Water, and Impurities in the Power Steering Fluid.
Typically, the presence of any impurities or air in the power steering fluid reduces its ability to lubricate the power steering system optimally.
Therefore, mechanical parts of the system are subjected to tension, friction, and pressure impacts that cause noise when turning the steering wheel while stationary. You can identify impurities by noting a difference in the power steering fluid color.
#8. Low Tire Pressure.
Low tire pressure can also cause a clicking sound when turning the steering wheel left or right when stationary. Low tire pressure causes an imbalance in the car weight distribution.
Therefore the steering system experiences discomfort when attempting to shift the tire direction causing extreme tension that brings about noises.
In addition to tire pressure, using worn-out tires or mixing different tire types can affect and cause power steering problems.
#9. Steering Pump Malfunctioning.
As mentioned earlier, the steering pump is responsible for creating sufficient pressure to support the power steering system. Therefore, pump impediments create a crucial problem for the steering system.
Although it may not hinder the steering movement completely, damaged pumps lead to further mechanical issues like torn steering belts which could damage the whole power steering system.
You notice malfunctioning steering pumps when the wheel becomes difficult to steer and makes a clicking noise in the steering column when steered in a stationary position.
Diagnosis and Inspection
To accurately diagnose the source of a popping noise when turning the steering wheel, a thorough inspection and diagnostic process is necessary.
Listen for the Noise While Stationary
Begin by listening for the noise while the vehicle is stationary and turning the steering wheel from lock to lock. This can help isolate the source of the noise and determine if it’s related to the steering or suspension components.
Inspect Suspension Components

| Inspection Point | Potential Issue |
|---|---|
| Strut Assemblies | Leaks or damage |
| Steering Rack/Box | Leaks or damage |
| Power Steering Components | Leaks or damage |
Perform a Test Drive
Conduct a test drive, paying close attention to when the popping noise occurs. Is it more pronounced during low-speed turns or high-speed maneuvers?
Does it happen when turning in both directions or only one? This information can help pinpoint the source of the issue.
| Observation | Potential Cause |
|---|---|
| Noise during low-speed turns | Ball joints, tie rod ends, suspension bushings |
| Noise during high-speed turns | CV joints, wheel bearings |
| Noise when turning in one direction | Steering rack/box, tie rod ends |
| Noise when turning in both directions | Ball joints, suspension bushings |
Use Diagnostic Tools
If available, use a mechanics stethoscope or chassis ear to help pinpoint the source of the noise while driving. These tools can amplify and isolate specific sounds, making it easier to identify the problematic component.
Safety Considerations
Ignoring a popping noise when turning the steering wheel can have serious safety implications. Worn or damaged steering and suspension components can lead to:
- Loss of control
- Increased wear on other parts
- Potential accidents or dangerous situations on the road
It’s crucial to address the issue promptly to ensure your safety and the safety of others. If you’re unsure about the cause or feel uncomfortable performing the necessary repairs, it’s always best to seek professional assistance from a qualified mechanic.
