How to Fix a Car That Makes Unusual Noises When Turning

Hearing strange noises when you turn your car can be unsettling. These sounds often indicate that something isn’t working as it should, and ignoring them could lead to more significant problems down the road. 

The good news is that you can diagnose and fix many of these issues with a little knowledge and the right tools. 

This guide will walk you through the common causes of unusual noises when turning and how to fix them.

Common Causes of Unusual Noises When Turning

Strange noises can vary, from clunking and squealing to groaning or popping. Each type of sound gives clues about the problem. 

Let’s look at the usual culprits:

• Low Power Steering Fluid
  • Sound: Whining or groaning noise when turning the steering wheel.
  • Cause: Power steering systems rely on hydraulic fluid. If the fluid is low, air can enter the system, causing noise.
• Worn or Damaged CV Joints
  • Sound: Clicking or popping noises, especially during sharp turns.
  • Cause: Constant velocity (CV) joints connect the transmission to the wheels. Over time, the protective boot can tear, allowing dirt to enter and grease to leak out.
• Faulty Wheel Bearings
  • Sound: Grinding or humming that gets louder as the car speeds up.
  • Cause: Wheel bearings allow the wheels to rotate smoothly. When they wear out, they can produce noises when the car turns.
• Loose or Worn Steering Components
  • Sound: Clunking or knocking noises when turning.
  • Cause: Components like tie rods, ball joints, or control arms may become loose or worn out.
• Brake Issues
  • Sound: Squealing or grinding noise while turning and braking.
  • Cause: Worn-out brake pads or debris in the brake system can create these sounds.
• Tire Problems
  • Sound: Thumping or squealing during turns.
  • Cause: Underinflated tires, uneven wear, or alignment issues can lead to noises when turning.

How to Fix Unusual Noises When Turning

Once you identify the potential cause, you can take steps to fix the issue. Below are solutions based on the most common problems.

1. Refill or Replace Power Steering Fluid

• Steps:
  • Open the hood and locate the power steering fluid reservoir.
  • Check the fluid level using the dipstick or markings on the reservoir.
  • If it’s low, top it up with the manufacturer-recommended power steering fluid.
  • Inspect for leaks in the system. If you find any, you may need professional help to repair or replace damaged hoses.

Pro Tip: Regularly check your power steering fluid to avoid recurring issues.

2. Repair or Replace CV Joints

• Steps:
  • Inspect the CV boot for tears or grease leaks.
  • If the boot is damaged, replace it immediately to prevent further harm to the joint.
  • If the CV joint is already worn out, it will need to be replaced.

Pro Tip: CV joint replacement can be tricky, so consult a mechanic if you’re unsure about handling this repair.

3. Replace Faulty Wheel Bearings

• Steps:
  • Jack up the car and remove the wheel near the noise source.
  • Check the wheel bearing for play by wiggling the hub assembly. Excessive movement indicates a bad bearing.
  • Use a bearing puller to remove the old bearing and install a new one.

Pro Tip: Replacing wheel bearings requires specialized tools. If you don’t have them, consider taking your car to a repair shop.

4. Tighten or Replace Steering Components

• Steps:
  • Inspect tie rods, ball joints, and control arms for looseness or visible wear.
  • Tighten any loose bolts or fasteners.
  • Replace any worn components with new ones.

Pro Tip: Misaligned steering components can cause uneven tire wear. Perform an alignment check after repairs.

5. Address Brake Issues

• Steps:
  • Inspect brake pads for wear. Replace them if they’re thin or damaged.
  • Remove any debris trapped in the brake system.
  • Check the rotors for grooves or warping. Resurface or replace them if necessary.

Pro Tip: Always replace brake pads in pairs (both front or both rear) to maintain balanced braking.

6. Fix Tire Problems

• Steps:
  1. Check tire pressure and inflate to the recommended level.
  2. Inspect tires for uneven wear or bald spots.
  3. Rotate or replace tires if needed.
  4. Perform a wheel alignment to correct tracking issues.

Pro Tip: Regularly rotating your tires extends their lifespan and prevents alignment issues.

Preventing Future Problems

Prevention is better than cure. Regular maintenance can help you avoid unusual noises when turning. 

Here are some tips:

• Check Fluids: Monitor power steering fluid levels and top up as needed.
• Inspect Tires: Regularly check tire pressure and alignment.
• Routine Servicing: Schedule regular inspections of steering, suspension, and braking systems.
• Listen to Your Car: Pay attention to new or unusual sounds and address them promptly.

When to Call a Professional

If you’ve tried the above fixes and the noise persists, it’s time to consult a professional mechanic. Some problems, like a failing steering rack or suspension issues, require specialized tools and expertise.

Final Thought

Unusual noises when turning are more than just an annoyance; they’re a sign that your car needs attention. 

By identifying the cause and addressing it early, you can save yourself time, money, and potential safety risks. 

With regular maintenance and quick action, your car will stay in top shape and turn silently, just as it should.
