What Causes the Hissing Friction Sound When Turning the Steering Wheel?
2 Answers
The reasons for the hissing friction sound when turning the steering wheel: 1. If the turn signal is activated while turning, this sound may be caused by the rebound clip of the automatic turn signal return mechanism; 2. If the abnormal noise comes from below the steering wheel, it might be due to the dust cover of the steering column. Lack of lubrication in the steering column dust cover can cause friction sounds; 3. If the noise originates from outside the vehicle, it could be due to insufficient lubrication in the shock absorber's plane bearing. If the plane bearing of the shock absorber is making noise, applying some grease to it may help. If the noise persists after greasing, replacement may be necessary.
When there's a hissing or friction sound from the steering wheel, my experience suggests it's mostly related to the power steering system. For example, insufficient fluid or air bubbles in the power steering pump can cause a sound similar to airflow when turning the wheel; a loose power steering pump belt can also produce friction noise, resembling belt slippage. For specific checks, you can start by opening the engine compartment hood and locating the power steering fluid reservoir to see if the level is between Min and Max. If the fluid has turned black, it's time to replace it. Try adding some new fluid yourself, but make sure to choose the correct type and not exceed the limit. If the fluid is normal but the sound persists, it might be due to air leaks in the pipes or pump wear, which requires professional tools for diagnosis. Don't underestimate this hissing sound—long-term neglect can lead to heavier and less responsive steering, which is especially dangerous if sudden steering failure occurs at high speeds. It's recommended to regularly check the fluid level during routine maintenance to prevent issues before they arise. If there's a problem, visit a repair shop early to avoid major repair costs.
