How to Fix a Car That Makes Noise When Turning
When you're driving, and your car starts making strange noises when you turn the steering wheel, it can be unsettling. Whether you're making a sharp left or a gentle right turn, these sounds often signal an issue with the vehicle. As someone who’s been through the process of diagnosing and fixing these types of problems, I understand how frustrating it can be. Not only can it be annoying, but if left unchecked, it can also point to serious issues with your car’s steering or suspension system. So, let me walk you through the steps I took to identify and fix the noise in my car when turning.

1. Identifying the Source of the Noise
The first thing you need to do when your car starts making noise while turning is to identify where the noise is coming from. Is it coming from the front of the car? The rear? The sound could be anything from a high-pitched squeal to a low, grinding noise. To begin the process, I carefully observed the following symptoms:
- Squealing or screeching: Often, this noise is related to the serpentine belt or a worn-out steering component.
- Grinding: This typically points to an issue with the power steering system or worn-out wheel bearings.
- Clunking: This sound may come from the suspension or steering linkage, such as a faulty tie rod or ball joint.
- Rubbing or scraping: Could indicate an issue with the brakes, like worn brake pads or debris stuck in the brake system.
By listening carefully and identifying the type of noise, you can narrow down potential causes. For me, the sound was a slight grinding noise that only occurred when I made sharp turns. This suggested there might be a problem with the power steering or suspension components.

2. Checking the Power Steering Fluid
One of the first things I checked was the power steering fluid level. Low fluid levels can cause the power steering pump to whine or create a grinding noise, especially when turning the wheel. Here's how I checked:
- Locate the power steering reservoir, usually near the engine, and ensure the engine is off and cool.
- Remove the cap, wipe the dipstick clean, then reinsert it and pull it out again to check the fluid level.
- If the fluid is low, top it off with the recommended power steering fluid for your vehicle.
- Start the car and turn the wheel to see if the noise persists.
If the fluid level was low and adding more fluid resolved the issue, that’s great! However, if the noise continued after topping up the fluid, it could indicate a more serious issue, such as a leak or a failing power steering pump. In my case, even after topping off the fluid, the noise remained, which led me to explore other causes.
3. Inspecting the Steering System
Next, I turned my attention to the steering system. The steering system is made up of several components that can wear out over time. I inspected the following parts:
- Steering rack: The steering rack is responsible for translating the motion of the steering wheel to the wheels. If it’s damaged or worn out, it can cause noises when turning.
- Tie rods: These are crucial for connecting the steering rack to the wheels. If they’re loose or worn, they can cause clunking or popping noises when turning.
- Ball joints: These allow the wheels to move smoothly as you turn. If they’re worn out, they can produce a knocking or clunking sound.
To inspect these parts, I jacked up the front of the car and gently wiggled the wheels to check for any excessive play in the steering system. I also listened carefully for any sounds coming from the steering rack or the tie rods. Sure enough, I noticed that the tie rods were a little loose, which was contributing to the noise when I turned the wheel.
4. Checking the Suspension Components
If the noise doesn’t come from the power steering or steering components, the next place to check is the suspension system. The suspension system is responsible for keeping your car’s wheels aligned and absorbing shock from the road. Worn-out suspension parts can cause a range of noises when turning, including clunks, pops, or rattling sounds. Here’s what I checked:
- Shock absorbers: If the shock absorbers are worn, they can create clunking noises, especially when turning or going over bumps.
- Ball joints and control arms: These components play a crucial role in the suspension’s performance. If they wear out, they can cause knocking sounds when turning.
I inspected the suspension components and noticed that one of the control arms had some play in it. This was likely the culprit of the clunking noise I was hearing when turning. Replacing the control arm resolved the issue, and the noise stopped immediately.
5. Inspecting the Wheel Bearings
If the noise you’re hearing sounds like a grinding noise and isn’t fixed by addressing the power steering or suspension system, then it’s time to check the wheel bearings. Wheel bearings are responsible for allowing the wheels to rotate smoothly. If they’re worn or damaged, they can cause a grinding or humming noise, especially when turning. Here’s how I checked:
- Jack up the car and secure it with jack stands.
- Grab the wheel at the 12 o’clock and 6 o’clock positions and try to wiggle it. If there’s play, the wheel bearing may be worn out.
- Listen carefully as you spin the wheel to check for any unusual sounds, such as grinding or roughness.
In my case, I found that the wheel bearing on the passenger side was severely worn, and that was causing the grinding noise when I turned. Replacing the wheel bearing was a relatively straightforward repair, but it did require removing the wheel, brake components, and the axle shaft, which made it a bit more involved than I initially expected.
6. Checking the Brakes and Rotors
If you’re hearing a scraping or rubbing sound when turning, the issue might be with your brakes. Worn-out brake pads or debris stuck in the brake system can cause noises, especially when you turn the wheel. Here's what I did to check:
- Remove the wheel and inspect the brake pads for wear.
- Check for any debris or rocks stuck in the brake components.
- Inspect the rotors for grooves, scoring, or damage.
In my case, I discovered that the brake pads were worn down and needed replacing. After replacing the brake pads and cleaning the brake system, the noise stopped. If you have a similar issue, it’s a good idea to replace the brake pads and inspect the rotors to ensure they’re not damaged.
7. Consider Professional Help
Sometimes, no matter how much you inspect and repair, there may be issues that are harder to diagnose or fix on your own. In such cases, I recommend taking your car to a trusted mechanic. They have the expertise and tools to perform more thorough diagnostics and repairs. If you’re not sure what’s causing the noise, or if the repairs are beyond your comfort level, a mechanic can provide the necessary assistance.
After following these steps, I was able to identify and resolve the noise in my car when turning. It took a bit of time and effort, but the satisfaction of solving the issue myself was well worth it. I hope this guide helps you diagnose and fix the noise in your car, saving you time and money in the process. If you’re ever in doubt, don’t hesitate to seek professional help.
