What Causes the Buzzing Sound When Turning the Steering Wheel?
2 Answers
Car steering wheel buzzing is related to the shock absorber pressure bearing, and the damage to the pressure bearing is largely connected to the operation technique. If the abnormal sound comes from inside the steering wheel, the issue is most likely caused by the steering wheel's clock spring (airbag spiral cable). Fault Diagnosis: If the abnormal sound comes from inside the steering wheel, the issue is most likely caused by the steering wheel's clock spring. Remove the clock spring and apply some grease to see if the noise persists. If it still buzzes, replace the clock spring as it is already damaged. Be gentle when removing the steering wheel, or disconnect the airbag fuse to prevent the airbag from deploying. Steering Wheel Usage Tips: Avoid turning the steering wheel while the car is stationary; try to steer only after the vehicle is in motion. When the car is parked, return the steering wheel to the neutral position to prevent unnecessary load on the suspension system and tires. When making a U-turn, try to avoid turning the steering wheel to its maximum limit.
I've been driving for over a decade and have encountered the humming sound when turning the steering wheel several times. This is mostly an issue with the power steering system. For example, if the power steering pump fails, has insufficient oil pressure, or internal wear, the system will produce that humming sound when you turn the steering wheel. Additionally, if the pump's belt is loose or worn, it can also create noise, but the humming sound is more commonly associated with the hydraulic components. If the steering gear or linkage has wear or excessive play, the noise will worsen. It's recommended to regularly check the power steering fluid level—top it up if it's low. If the fluid level is normal, you should take it to a professional shop for inspection. Don't ignore this small issue, as the steering system could completely fail, making driving very strenuous and especially dangerous when turning. Addressing it promptly can save you a significant repair cost and extend your vehicle's lifespan.
