Car Makes Noise When Turning: What's the Cause and How to Fix It?
Hearing unusual noises from your car, especially when turning, can be a worrisome experience. It could indicate a minor issue or a more serious problem that needs immediate attention. This article will guide you through some of the common causes of noises when turning and what you can do to fix them.
Common Reasons for Noise When Turning
Here are the most likely culprits for that unsettling noise your car makes when you turn the steering wheel:
1. Power Steering Fluid:
- The Issue: Low power steering fluid is a common cause of noise when turning. The fluid helps lubricate and cool the power steering system. When the fluid level is low, the pump struggles to generate enough pressure, leading to a whining or groaning sound.
- Solution: Check the power steering fluid reservoir. If it's low, top it off with the correct type of fluid (usually ATF - Automatic Transmission Fluid). If the level is consistently low, there might be a leak, which needs to be addressed by a mechanic.
2. Worn-Out Steering Rack:
- The Issue: The steering rack is responsible for converting the steering wheel's movement into wheel movement. A worn-out rack can cause clicking, grinding, or clunking noises when turning, especially at low speeds.
- Solution: Replacing the steering rack is often the only solution. This is a job best left to a mechanic as it involves specialized tools and expertise.
3. Worn Suspension Components:
- The Issue: Worn-out suspension components like ball joints, control arms, or tie rod ends can create a knocking or clunking sound when turning. These parts are designed to allow for smooth suspension movement but can wear down over time.
- Solution: A mechanic needs to inspect the suspension components. They may need to be replaced or tightened.
4. Worn Wheel Bearings:
- The Issue: Wheel bearings support the weight of your car and allow the wheels to rotate smoothly. Worn wheel bearings can cause a grinding or rumbling sound, especially when turning.
- Solution: The affected wheel bearing needs to be replaced. It's crucial to address this issue promptly as a damaged bearing can cause your wheel to seize up while driving.
5. Loose or Damaged CV Joints:
- The Issue: Constant Velocity (CV) joints are located in the drive shafts and allow the wheels to turn at different angles without losing power. A worn or damaged CV joint can cause a clicking or popping noise when turning.
- Solution: The damaged CV joint needs to be replaced. This is a relatively complex repair that requires specialized tools and knowledge.
6. Brake Rotors or Pads:
- The Issue: Worn or warped brake rotors can cause a grinding or squeaking sound when turning. This can also happen with worn or contaminated brake pads.
- Solution: Inspect the brake pads and rotors. Worn pads need to be replaced, and warped rotors might need to be resurfaced or replaced.
7. Wheel Alignment Issues:
- The Issue: Incorrect wheel alignment can cause uneven tire wear and unusual noises when turning. This is often accompanied by a feeling of the car pulling to one side.
- Solution: Get a wheel alignment done by a professional mechanic.
8. Loose Steering Column:
- The Issue: A loose steering column can lead to clunking or rattling noises when turning. This is less common but can occur due to wear or impact.
- Solution: A mechanic can inspect the steering column and tighten or replace any loose parts.
When to Seek Professional Help
If the noise is severe or persistent, or if you notice any other unusual symptoms like steering wheel vibration, difficulty turning, or fluid leaks, it's best to consult a mechanic right away. They can diagnose the problem accurately and provide the necessary repairs to restore your car's safety and smooth operation.
Remember: Ignoring a noise when turning could lead to more serious damage and potential safety hazards.
