Common Causes of Popping Sounds While Turning Your Vehicle

Common Causes of Popping Sounds While Turning Your Vehicle

Hearing a strange popping noise while turning your vehicle can be alarming. It often signals an underlying issue with the suspension or steering system, which should not be ignored. Here are some common causes of this sound and what they might indicate about your vehicle’s condition.

1. Bad Strut Mount Assembly

The strut assembly reduces road shock and is part of your car’s steering system. It includes a bearing that helps with pivoting. When the strut mount is worn, you’ll often hear a popping noise when turning. This could also lead to tyre wear and steering vibrations.

2. Worn or Damaged Ball Joint

Ball joints are essential components of your vehicle’s suspension and steering systems. They connect the steering knuckle to allow pivoting while turning. A popping or clunking noise can occur if these components become worn or damaged, especially during turns.

3. Bad CV Joints

If your car is a front-wheel drive, it has Constant Velocity (CV) axles that transfer power from the engine to the front wheels. Over time, the outer CV joints, which allow for smooth turning, can wear out, causing a popping or clicking noise when you turn and accelerate.

4. Broken Coil Spring

The coil spring is an important part of the suspension system, helping to absorb shock from road imperfections. When a coil spring breaks, you may hear a popping, knocking, or clunking sound, which can also lead to alignment issues and uneven tyre wear.

5. Defective Struts

Struts, which work alongside coil springs to absorb shocks, can also cause a popping sound when damaged. If the piston or internal components fail, the strut will no longer effectively absorb impacts, causing odd noises during turns.

6. Worn Control Arm Bushings

Control arm bushings connect the suspension to the frame of your car. When these bushings wear out, they can produce a popping or snapping sound when you turn the wheel. Over time, this sound may worsen and lead to squeaking.

How To Fix the Popping Noise

Addressing the cause of the popping noise requires careful inspection and part replacement. Here’s a general guide on how to diagnose and fix the issue:

1. Determine Which Side the Noise is Coming From

Start by identifying which side of the car the noise is coming from. This will help you pinpoint where to focus your inspection. Having a friend ride with you while you turn can help narrow it down.

2. Inspect Coil Springs and Strut Mounts

Lift the car and visually inspect the coil springs and strut mounts for any obvious signs of damage or wear. Not all issues may be visible immediately, so further investigation may be necessary if nothing is apparent.

3. Check the Suspension and Bushings

Look under the car at the bushings and suspension components. If any bushings are separating or worn, they’ll need to be replaced. Make sure to also check the tie rod ends for excessive play, as these connect the steering to the wheels.

4. Replace Broken or Worn Parts

If any parts are damaged or worn, replace them. It’s a good idea to replace suspension parts in pairs (e.g., both coil springs) to maintain vehicle balance. While working on the suspension, inspect other components like ball joints and bushings to ensure they are in good condition.

By following these steps, you can identify and resolve the source of the popping noise, improving your vehicle’s performance and safety. If you’re unsure or unable to fix the issue, consulting a professional mechanic is always a good option.
