When your car makes noises while turning, it often indicates an issue with the suspension or steering parts. These mechanical systems, over time, accumulate dirt and wear, leading to unusual sounds. As cars age and miles add up, linkages and other components can become loose or worn, causing concerning noises when you turn the steering wheel.
Diagnosing the problem early can prevent expensive repairs. It’s important to take steps to identify the cause of the sounds. Understanding the root causes helps in diagnosing and repairing the issue effectively, ensuring your car remains safe and reliable.

Common Causes of Noises When Turning
When turning, noises such as clunks, rattles, and thumps might occur due to various categories of mechanical issues. Rotational noises often arise from worn components, causing clinking or knocking sounds during motion.
Pops and squeals may signal problems with the steering system, particularly when turning. Each of these noises, whether subtle or loud, indicates specific issues that can be identified by paying attention to their unique characteristics. Understanding the categories of these sounds can help diagnose the root causes of the noises when turning.
Tire-Related Issues
One common reason for weird noises when you turn is your car’s tires. Here are some tire issues to think about:
Tire tread wear. If your tire treads are worn unevenly, your car might make noise, like squealing, when you turn. Look at your tires for signs of uneven wear or unusual patterns. Rotating your tires regularly can help avoid this problem.
Low tire pressure. Low tire pressure can make the edges of your tires wear out faster. It also makes the wheel work harder against the road, causing squealing or scuffing noises. Check that your tires are inflated to the right level for your vehicle.
Power Steering Problems
Your car’s power steering system helps you steer easily. But it can sometimes make noise:
Low power steering fluid. If your power steering fluid is low or empty, you might hear a whining or groaning noise when you turn the wheel. Check the fluid level and add more if needed. Also, look for any leaks in the system.
Worn power steering pump. If your power steering pump is worn out, it might make a high-pitched squeal or a droning noise when you turn. If you hear this, it might be time to replace the pump.
Suspension and Steering Components
Issues with your car’s suspension and steering can also cause strange noises:
Worn ball joints or bushings: If these parts are worn out, they can make clunking or knocking sounds when you turn. Check them and replace if needed.
Loose or damaged tie rod ends: These parts connect your steering to the wheels. If they’re loose or broken, they can make clicking or popping noises, and rattle over bumps. They might need replacing.
Seized strut bushings: The upper mount on front struts can get dirty or rusty. This can make steering feel off and cause popping or crunching noises.
Damaged CV joints: If a CV boot on an axle shaft is torn and dirt gets in, it can cause popping noises when you turn.
Brake-Related Concerns
Sometimes, the noise could be due to your brakes:
Worn brake pads: If you hear a grinding noise while turning, it might be because your brake pads are worn out. Check them and replace them if they’re too thin.
Caliper issues: Problems with the brake calipers, like a stuck caliper or worn pins, can also cause noise when you turn. Have a mechanic check and fix any caliper problems.
How to Diagnose the Problem
To diagnose the problem, start with a visual inspection of your vehicle. Check the tires for any signs of wear or damage. Inspect the undercarriage for leaks or loose parts. The power steering fluid reservoir should be examined for low fluid levels or leaks.
During a test drive, listen for any unusual sounds like squeals, thuds, clicks, or grinding noises. Observe how the vehicle behaves during slow and sharp turns. Note any differences in noise when driving straight versus turning.
Replicate the conditions that cause the noise to better diagnose the issue. A grinding noise might indicate worn components, while a squeal could be due to loose parts. Identifying and noting these sounds can reveal the problem’s source. Continue to inspect and observe all components to pinpoint the underlying issue.
Addressing the Issue
Addressing the issue of car noises when turning involves several DIY steps. Start by checking tire pressure; properly inflated tires reduce noise. Ensure tires are rotated regularly to avoid uneven wear. Inspect power steering fluid levels for leaks, which can cause noises.
Examine the suspension system for loose or worn parts. Worn brake pads or components might also be a source of the noise. If you find any issues, such as loose parts or leaks, consider whether they need to be corrected or replaced.
If the problem persists, it may be time to consult a professional mechanic. Their expertise and specialized tools will help diagnose and fix the problem accurately. Consider the extent and location of the issue when discussing prices for repairs. Some issues might be minor and budget-friendly, while others could require a more significant investment.
Preventative Maintenance Tips
To prevent future steering noise issues, follow these simple tips:
Check your tires for wear. Uneven wear may signal other problems.
Stick to your car’s maintenance schedule. Regular upkeep can help catch issues early and prevent noise.
Monitor power steering fluid levels. Low or dirty fluid should be addressed quickly to avoid wear.
Fix problems promptly. Early repairs prevent more damage.
