Reasons for Buzzing Sound When Turning the Steering Wheel in Haval H6
2 Answers
Haval H6 steering wheel buzzing sound can be caused by friction between plastic components, issues with the steering wheel airbag clock spring, etc. Specific explanations are as follows: Friction between plastic components: Most parts of the car steering wheel are made of plastic. At lower temperatures, the plastic hardens, and friction between these components can cause abnormal sounds, which is a normal occurrence. Steering wheel airbag clock spring issue: In this case, the abnormal sound usually comes from inside the steering wheel. Applying some grease to the steering wheel airbag clock spring may help. If the sound persists, the airbag clock spring needs to be replaced. Loose or damaged stabilizer bar: Abnormal sounds can also occur when driving on rough roads. Adding shims to the stabilizer bar might solve the problem; if not, the stabilizer bar needs to be replaced. Problems with the shock absorber top bearing: If the shock absorber top bearing lacks lubrication, it can also cause abnormal sounds. Open the engine hood to identify the source of the sound. If it comes from the shock absorber top mount, the component needs to be replaced.
I've been driving my Haval H6 for over three years and recently noticed a humming sound when turning the steering wheel. This is usually caused by insufficient oil or deteriorated fluid in the power steering pump, as overly dirty fluid increases the pump's operating resistance. It could also be due to the aging and loosening of the power steering pump belt—last time I checked, I found small cracks in the belt. Worn gears inside the steering gear can produce similar noises, especially noticeable during sharp turns. If the sound worsens in cold weather, it's likely due to the fluid thickening, so it's advisable to switch to low-temperature steering fluid before winter. It's best to regularly check the color of the power steering fluid; it should be clear and slightly red when normal. If it turns black, replace it immediately to avoid damage to the entire power steering system.
