Why is there a noise when turning the car steering wheel?
3 Answers
Reasons for noise when turning the car steering wheel are as follows: Friction sound between steering column and floor mat: If the abnormal noise is heard from below the steering wheel when turning, check the contact between the steering column and the car floor mat. Oversized aftermarket floor mats may directly contact the steering column, causing friction during rotation. Lack of lubrication can produce friction noise, which can be resolved by applying some lubricant. Clock spring (spiral cable) malfunction: If the sound comes from inside the steering wheel, it's likely caused by interference from the clock spring inside. Remove the steering wheel and apply some grease to the clock spring. If the noise persists, replace the clock spring as it may be damaged.
When the steering wheel makes noise while turning, it often indicates an issue with the steering system. Based on my years of car ownership experience, this typically stems from several causes: First, wear in the universal joint or steering rack below the steering wheel can produce squeaking sounds when turning due to lack of lubrication, which is common in older vehicles. Second, loose ball joints or suspension links may cause noise from tire and component friction during turns, especially noticeable on bumpy roads. Third, power steering assistance problems, such as insufficient hydraulic pump fluid or electric power steering motor failure, often result in a humming sound. Fourth, aging internal components like horn contacts inside the steering wheel can also create unusual noises when loose. I've personally encountered this issue in several cars I've owned, primarily due to insufficient lubrication, which was resolved by adding lubricant. Ignoring these noises may lead to increased steering effort, accelerated wear, or even compromised handling safety. I recommend starting with simple checks, such as verifying fluid levels or listening for the noise source while turning the wheel. If the noise persists, consult a professional mechanic for diagnostic tools. Regular maintenance should include attention to lubrication and fastener conditions, with suspension system inspections every six months to prevent such issues.
What's the cause of the steering wheel making a noise when turning? I think it's related to daily driving habits. You might be experiencing similar issues: the steering universal joint or rack is loose, causing friction and noise when turning, like the sound of a bicycle chain getting stuck. In power steering vehicles, if the power steering pump oil is low or aged, it can also produce a humming noise. I've had my steering wheel make noise when turning before—initially thought it was a tire issue, but after checking, it turned out to be a loose small component that just needed tightening. Loose tire suspension systems are also common; for example, when the ball joint is severely worn, steering can produce a squeaking sound. Don't panic if you encounter this issue—try diagnosing it yourself first: park the car steadily and slowly turn the wheel to locate the noise. If your car has automatic or electric power steering, check if the related system is functioning properly. Infrequent noises might not affect safety, but ignoring them for a long time can make steering more difficult and increase repair costs. It's advisable to schedule a comprehensive inspection at a garage or service center, or combine it with your next oil change for lubrication and maintenance. Remember to drive smoothly and avoid sharp turns to reduce wear and tear.
