What Causes the Friction Sound When Turning the Steering Wheel?
2 Answers
The reasons for friction sound when turning the steering wheel are: 1. Lack of lubrication: Friction sound between the steering column and floor mat; If you hear abnormal noise coming from below the steering wheel when turning it, check the steering column and car floor mat. An oversized aftermarket floor mat may directly contact the steering column, causing friction as the column rotates. Insufficient lubrication can lead to friction noise, which can be resolved by applying some lubricant. 2. Clock spring (spiral cable) failure: If the noise originates from inside the steering wheel, it's often caused by interference from the clock spring inside. Remove the steering wheel and apply some grease to the clock spring to see if the noise persists. If it does, replace the clock spring as it may be damaged. 3. Lack of lubrication in shock absorber top bearing: If the abnormal noise comes from outside the vehicle when turning the steering wheel, it might be due to insufficient lubrication in the shock absorber's top bearing. Open the hood and listen to determine if the noise comes from the shock absorber top mount location. If confirmed to be from the shock absorber top bearing, apply grease. If the noise continues after lubrication, replacement is necessary.
As someone who works with cars year-round, I often encounter steering wheel friction noises, which are commonly caused by gear wear or lack of lubrication inside the steering gear. When gear clearance increases or the grease dries up, metal components rubbing directly against each other produce the sound. It could also be an issue with the power steering system, such as rusted motor bearings in electric power steering or pressure differential changes due to hydraulic hose leaks. Accumulated dust in chassis components like ball joints or tie rod connections can also cause noise. I've handled similar cases—adding lubricant can help in early stages with mild symptoms, but severe cases require replacing the entire steering gear assembly. If left unaddressed, steering responsiveness will decline, and sudden lock-ups at high speeds are extremely dangerous, especially in rainy conditions when skidding is more likely. My personal advice: don’t hesitate—take your car to a repair shop ASAP for professional diagnostics. DIY attempts might make things worse.
