Do you hear a strange noise or creaking sound every time you turn your steering wheel? Various factors can cause steering wheel noise, and it’s essential to understand what they are and how to address them.
When turning your steering wheel, it should be relatively quiet, except for a slight power steering pump noise, especially when making low-speed manoeuvres. Any other sounds or noises are a sign that something may require attention in the steering or suspension systems.
Here are potential causes of steering wheel noise when turning and what you can do to fix it:
Faulty steering rack
The steering rack is usually durable and requires minimal maintenance, but dirty power steering fluid or a malfunctioning power steering pump can damage it and shorten its life. One of the early warning signs of a faulty steering rack is clicking or whining noises when turning, particularly at low speeds. Such steering wheel noises can be a symptom of a faulty steering rack, which can affect the overall driving experience.
Low power steering fluid level
Another reason you may hear some steering wheel noise when turning is the low power steering fluid level. The power steering system needs power steering fluid to function. It acts as a lubricant for the moving components in the system. Its level barely drops unless there is a leak in the system. When this happens, it denies the system the much-needed lubrication and results in a whining noise.
Dry ball joints
Ball joints are a crucial component in your vehicle’s suspension system, linking the control arm and the steering knuckle. It needs to be lubricated to function well. However, over time, the lubrication can degrade, leading to increased wear and tear. One common symptom of worn ball joints is a rattling or clunking steering wheel noise when turning. This means that the ball joint is failing and needs to be replaced as soon as possible.
Faulty serpentine belt
The serpentine belt is a critical component that transmits power from the engine to several essential parts including the power steering pump. With the wear and tear of daily use, the belt can become weak and need replacement. A clear sign of a worn serpentine belt is a steering wheel noise, specifically a high-pitched squealing or whining sound when turning the wheel.
Potential solutions for steering wheel noise while turning
If your vehicle produces a screeching or high-pitched noise while turning the steering wheel, it’s most likely that the problem lies within the power steering system. To pinpoint the cause of the noise, start by checking the power steering fluid level while ensuring the filter is clean. You should also inspect the serpentine belt for any noticeable cracks or signs of damage. These are common problems you may address at an auto-parts store or service centre. If the noise continues, your car might have a larger issue with the power steering pump.
Grinding, knocking or rattling noises while turning the steering wheel means there’s a problem with the suspension. You should never ignore these steering wheel noises, as they can pose a danger. You can easily inspect some suspension parts for damage. However, you should have a professional mechanic inspect and replace them if necessary.
