In this comprehensive guide, we’ll demystify the eight primary reasons causing the scraping noise when turning left at a low speed, and we’ll provide solutions to fix them. Moreover, we’ll also address some common queries related to this issue. But before we delve into it, let’s try to understand what we mean by a scraping noise.
| Reason | Cause | Fix |
|---|---|---|
| Something caught in the wheel | A small rock or piece of gravel that’s become lodged between the tire and the wheel well | Inspect the wheel and remove any foreign object that’s causing the noise |
| The brake pads need to be replaced | The brake pads wear down and become too thin, causing a metal-on-metal scraping sound as they rub against the brake rotors | Replace the brake pads as soon as possible and check the condition of the brake rotors |
| The car is out of alignment | The wheels are not parallel to each other and point in different directions, causing them to rub against each other as you turn | Take your car to a mechanic and have the wheels aligned |
| The power steering fluid is low | The fluid level is low, causing the power steering pump to work harder and make a scraping noise | Check the power steering fluid level and add more if it’s low and check for any leaks or cracks in the power steering system |
| The shocks are worn out | The shocks can’t dampen the movement of the suspension as well, causing the tires to rub against the wheel wells as you turn | Replace the shocks as soon as possible and check the condition of the springs, struts, and bushings that support the shocks |
| The CV joint is damaged | The CV joint is exposed to contamination and corrosion due to a cracked or torn rubber boot, causing a scraping noise when turning | Replace the CV joint as soon as possible and replace the CV boot and grease the new CV joint properly |
| The wheel bearing is bad | The wheel bearing is contaminated or worn out due to a damaged or loose metal cap, causing a scraping noise when turning | Replace the wheel bearing as soon as possible and check for any damage or wear on the hub, axle, or spindle that support the wheel bearing |
| The sway bar is loose or broken | The sway bar is attached to the suspension by bushings and links that are loose or broken, causing the sway bar to move excessively and make a scraping noise when turning | Tighten or replace the sway bar bushings and links as soon as possible and check the condition of the sway bar itself |
Defining a Scraping Noise
Imagine the harsh sound produced when two metal surfaces slide against each other; that’s what a scraping noise sounds like. The intensity and frequency of this noise can vary, primarily depending on the root cause and the speed of the vehicle.
But remember, a scraping noise is not the same as a squeaking or grinding noise – two other common sounds heard when turning. A squeaking noise, often high-pitched, is typically the result of friction between rubber or plastic parts, while a grinding noise, usually low-pitched, is caused by worn-out or damaged metal components.
This guide will specifically focus on the scraping noise that comes into play when you take a left turn at low speed. Wondering why a similar problem, but occurring when turning right, might have different implications?

The Importance of Addressing Scraping Noise
You may think, “Why such a fuss over a noise?” Well, the reason is that a scraping noise when turning left at low speed can signal a problem with your vehicle’s essential components, such as the steering system, suspension, brakes, or wheels. These elements are critical for your car’s performance, safety, and handling capabilities.
Ignoring a scraping noise can lead to potentially hazardous situations, including:
- Reduced braking efficiency and extended stopping distance
- Loss of steering control, escalating the risk of accidents
- Damage to the tires and wheels, leading to accelerated wear and tear
- Potential harm to the engine and transmission, negatively affecting fuel efficiency
That’s why identifying and addressing the source of the scraping noise as promptly as possible is of utmost importance.
Diagnosing The Cause
So, how can you identify the culprit causing that scraping noise when you take a left turn at a slow pace? Look for clues like:
- The timing and conditions of the noise – Does it only occur when turning left or also when turning right? Is it exclusive to low speeds or does it persist at high speeds as well? Is it linked to your braking or acceleration actions?
- The origin of the noise – Can you discern if it’s coming from the front or rear wheels? Is it from one side or both? Can you tell if it’s an internal or external sound?
- The nature of the noise – Is it loud or soft? Consistent or intermittent? Smooth or rough?
Your answers to these questions can help you pinpoint the potential causes
. Now, let’s uncover the eight key reasons behind this particular issue.
Top 8 Reasons for Scraping Noise When Turning Left at Low Speed
1. Something is caught in the wheel
Imagine you’re driving along a country road, and suddenly a small stone or a stick gets caught in the wheel well or the brakes. Unknowingly, you carry on driving. But when you take a left turn, you hear a peculiar scraping sound. The simple explanation? That foreign object lodged within your wheel.
How to fix it: The solution here is as simple as the problem – carefully inspect the wheel wells and brakes to find the intrusive object and remove it. Always ensure your safety while doing so; the object might be hot or sharp.
2. Worn-out brake pads
Your vehicle’s brake pads take quite a beating every time you drive, gradually wearing down. Over time, the protective layer of the brake pad becomes thin, and the metal base starts to come in contact with the brake rotor. This metal-on-metal interaction is often the cause of a scraping noise, especially when turning left at low speed.
How to fix it: The worn-out brake pads need replacement. Whether you choose to do it yourself or take it to a professional mechanic is a personal choice based on your comfort level and expertise. If you’re experiencing related issues such as shaking when accelerating, you might want to read our article on Steering Wheel Shaking When Accelerating for more insight.
3. Misaligned wheels
An improperly aligned wheel can rub against the wheel well or the steering components when turning, causing a scraping noise. This problem is more likely to surface when turning left at low speeds due to the added pressure on the left wheel.
How to fix it: If misalignment is the root cause, getting your car wheels realigned by a professional mechanic can help resolve the issue.
4. Low power steering fluid
If your power steering fluid level is low, it can make your power steering pump work harder, leading to a scraping noise when turning left at low speed. Besides, low fluid can also cause your steering wheel to feel heavy or stiff.
How to fix it: Check your power steering fluid level. If it’s low, top it up with the recommended type of fluid. Be cautious to avoid overfilling it.
5. Worn-out shocks
Your car’s shocks or struts absorb the bumps on the road to offer a smoother ride. Over time, they wear out and can make a scraping noise when turning, particularly at low speeds due to increased pressure on the suspension components.
How to fix it: Replacing the worn-out shocks or struts can solve the problem. A professional mechanic should ideally perform this task.
6. Damaged CV joint
Constant Velocity (CV) joints are part of the drivetrain and allow your car to maintain constant speed while turning. A damaged CV joint can make a scraping noise, specifically when turning left at low speed.
How to fix it: Replacing the faulty CV joint will rectify the issue. Again, this task is best left to a professional mechanic due to its complexity.
7. Bad wheel bearing
The wheel bearing allows your car’s wheels to rotate smoothly. When it goes bad, it can cause a scraping noise when turning left at low speed, as the left wheel bears more weight.
How to fix it: A bad wheel bearing requires replacement. Whether you DIY or take your car to a mechanic depends on your comfort level with the task.
8. Loose or broken sway bar
The sway bar connects the left and right wheels,
ensuring balance and stability when turning. If its links or bushings are loose or broken, they can create a scraping noise when turning left at low speed.
How to fix it: You’ll need to tighten or replace the sway bar bushings and links. Also, inspect the sway bar itself for any deformity and replace it, if necessary.
How to Prevent Scraping Noise When Turning?
Prevention is always better than cure, and it’s the same with the scraping noise issue. Regular maintenance of your vehicle can help prevent the scraping noise from ruining your peaceful drives.
Here’s what you need to do:
