Whining when turning steering wheel?


Whining when turning the steering wheel can be a frustrating and concerning issue for car owners. This article will explore the possible causes of this problem and provide insights into how it can be resolved.

Possible Causes

There are several potential reasons why a whining noise may occur when turning the steering wheel. Understanding these causes can help in diagnosing and resolving the issue effectively.

Low Power Steering Fluid: One common cause of whining while turning the steering wheel is low power steering fluid. The power steering system relies on an adequate amount of fluid to function properly. When the fluid level is low, it can result in a whining noise. Checking the power steering fluid reservoir and topping it up if necessary can often resolve this issue.

Worn Out Power Steering Pump: Another possible cause of whining when turning the steering wheel is a worn-out power steering pump. Over time, the internal components of the pump can wear out, leading to noise generation. If the power steering pump is the culprit, it may need to be replaced to eliminate the whining noise.

Loose or Worn Serpentine Belt: The serpentine belt in a car’s engine is responsible for powering various components, including the power steering pump. If the belt becomes loose or worn, it can slip and cause a whining noise when the steering wheel is turned. Inspecting the serpentine belt for signs of wear or tension issues and replacing it if necessary can often resolve this problem.

Steering Gear Problems: Issues with the steering gear, such as a worn-out steering rack or damaged bearings, can also result in a whining noise when turning the steering wheel. These components may need to be inspected and repaired or replaced by a professional mechanic to resolve the issue.

Other Factors: In some cases, the whining noise when turning the steering wheel may be caused by factors unrelated to the power steering system. For example, worn-out wheel bearings or suspension components can also generate similar noises. It is important to consider these possibilities and have a thorough inspection of the vehicle to identify the exact cause.


Resolving the whining noise when turning the steering wheel depends on identifying the underlying cause. If the issue is related to low power steering fluid, simply topping up the fluid reservoir can solve the problem. However, if the cause is more complex, it is recommended to seek the assistance of a qualified mechanic. They will be able to diagnose the issue accurately and perform the necessary repairs or replacements.

Regular maintenance of the power steering system, including checking the fluid level and condition, can help prevent issues like whining noises. Following the manufacturer’s recommended service intervals and addressing any problems promptly can prolong the lifespan of the power steering components and ensure smooth and quiet operation.


Whining when turning the steering wheel can be caused by various factors, including low power steering fluid, a worn-out power steering pump, loose or worn serpentine belt, or steering gear problems. Identifying the specific cause is crucial in resolving the issue effectively. Regular maintenance and prompt attention to any problems can help prevent such noises and ensure optimal performance of the power steering system.
