Why Does My Car Make Noise When Turning?

Anyone who’s ever been behind the wheel of a car can tell you that a smooth, quiet turn is one of those simple, but vital, parts of driving. But what happens when that gentle, effortless turn suddenly becomes a grinding, scraping, or clicking sound? If you’re hearing strange noises when you turn your car, it’s not just an inconvenience—it’s a sign that something may be wrong with your vehicle. And while it might seem tempting to ignore the sound, doing so could lead to more severe problems and costly repairs in the future.

Why a Smooth Turn is Essential for Vehicle Safety

When you turn your vehicle, several key components work together to ensure that the turn is safe and controlled. Power steering, suspension systems, and brakes are all engaged to make the turn feel effortless and keep your car in control.

If any of these components begin to fail, it can create noticeable issues, such as difficulty steering, a bumpy ride, or strange noises. A grinding noise while turning indicates that something is amiss, and diagnosing the problem early is essential to prevent further damage and ensure that your car remains in top shape.

What it Means When Your Car Makes a Grinding Noise While Turning

A grinding noise when turning can mean several different things. It’s important to pay attention to when the noise occurs, whether it happens while turning left, right, or both, and the type of noise (grinding, clicking, or squealing). All of these factors can help narrow down the cause.

The noise itself is often a sign of a mechanical problem that needs to be addressed. Ignoring these sounds can lead to more serious issues down the road, so addressing the problem early is key to preventing a simple fix from turning into a major repair.

Common Causes of Grinding Noise While Turning

1. Worn-Out CV Joints

Constant velocity (CV) joints are an essential part of your car’s drivetrain. These components transfer power from the engine to the wheels, allowing your car to move smoothly and turn with ease. When your CV joints wear out, it can lead to a variety of issues, including a loud grinding or clicking sound when turning left or right.

Signs of Failing CV Joints:

• Clicking or popping noises when turning.
• Grinding noises are more pronounced during sharp turns.
• Vibrations while driving at higher speeds.

2. Failing Wheel Bearings

Over time, these wheel bearings can wear out, leading to friction that causes grinding noises when turning. The problem often becomes more noticeable at higher speeds, where the load on the bearings is greater.

Symptoms of Bad Wheel Bearings:

• A grinding noise that increases with speed.
• Noise that gets louder when turning left or right.
• A rumbling sound that persists even when the car is coasting.

3. Damaged Power Steering Components

Power steering is what makes turning your car feel easy and controlled. If you’re hearing a grinding noise when turning, it could be a sign of low power steering fluid or a failing power steering pump. In some cases, the steering rack or other components in the power steering system may also be to blame.

Signs of Power Steering Problems:

• A whining or grinding noise when turning the wheel.
• Difficulty steering, especially at low speeds.
• A jerking or unresponsive feeling when you turn the wheel.

4. Brake System Issues

Your brake system plays a significant role in both stopping and controlling your car. A grinding noise when turning could also be a sign that your brake pads are worn down, your rotors are damaged, or your brake calipers are malfunctioning. In these cases, the grinding sound occurs when the brake pads or other components make contact with the rotors while turning.

Brake Issues to Look Out For:

• Grinding noises when turning or braking.
• Squeaking or squealing sounds that persist while driving.
• Reduced braking power or responsiveness.

5. Suspension Problems

The suspension system of your vehicle includes a variety of parts, such as struts, control arms, and ball joints, that work together to ensure a smooth and stable ride. If any of these components become worn or damaged, it can lead to friction and noise when turning.

Symptoms of Suspension Issues:

• Grinding or clunking sounds when turning the steering wheel.
• A bumpy or unstable ride when driving over uneven surfaces.
• Difficulty controlling the vehicle, especially when making sharp turns.

Diagnosing the Grinding Noise: Step-by-Step Guide

If you’re hearing grinding noises while turning, follow these steps to diagnose the issue:

1. Identify the Direction:
   • Pay attention to whether the noise happens when turning left, right, or both. This can help pinpoint the source of the issue.
2. Listen for Additional Sounds:
   • In addition to grinding, listen for clicking, clunking, or humming sounds. Different types of noises can indicate different problems.
3. Inspect Key Components:
   • Check the CV joints, wheel bearings, brakes, and suspension for visible signs of wear or damage.
4. Test Drive:
   • In a safe location, attempt to recreate the noise by turning the steering wheel. Take note of any patterns or changes in the sound.

Solutions to Fix Grinding Noise While Turning

If you’ve diagnosed the problem and it involves any of the components mentioned above, here’s how to address the issue:

1. Replacing CV Joints or Axles:
   • If your CV joints are the cause, they may need to be replaced. This is a job best left to professionals, and Burt Brothers is ready to help with both repairs and replacements.
2. Fixing Wheel Bearings:
   • Wheel bearings can be replaced to restore smooth turning. Professional replacement ensures that the job is done right the first time.
3. Power Steering Repair:
   • If low fluid or a failing pump is the cause, topping up the fluid or replacing the pump can restore proper steering function.
4. Brake System Maintenance:
   • If your brakes are the problem, replacing worn brake pads, resurfacing rotors, or repairing calipers can resolve the grinding noise.
5. Suspension Repair:
   • Worn struts, ball joints, and control arms can be repaired or replaced to eliminate the noise and ensure smooth handling.

When to Seek Professional Help

While some of these issues can be addressed with basic maintenance, others may require professional attention. If the grinding noise persists despite your efforts, or if you’re experiencing difficulty steering or a loss of control while turning, it’s time to bring your car to a professional at Burt Brothers. Ignoring grinding noises can lead to expensive repairs down the road, so it’s best to address the issue early.
