What causes abnormal noise during low-speed steering?
4 Answers
When a car produces abnormal noise, the first step is to identify the source of the noise. Here are specific explanations: 1. Sound from turn signal reset: If the turn signal is activated while steering, the noise may come from the reset mechanism's recoil latch. The owner should verify this situation. If confirmed, it is a normal occurrence. 2. Noise from steering column dust cover: If the noise originates below the steering wheel, it might be caused by the steering column dust cover. Lack of lubrication in the dust cover can generate friction noise.
After driving for so many years, I've found that low-speed steering noises are quite common, mostly due to issues in the steering system or suspension components. If the power steering pump's belt is loose or worn out and lacks oil, it may produce squeaking or clicking noises when turning the wheel. Worn suspension ball joints or bearings can also cause clunking sounds under turning loads. Uneven tire pressure or deformed tread patterns can create friction noises as well. These noises are usually more noticeable at low speeds because the slower vehicle movements expose more issues. For self-inspection, I first try to identify the source of the sound when turning—whether it's near the steering wheel or around the wheels—then check if the power steering fluid level is sufficient, topping it up if low. If accompanied by a heavy steering wheel, it might indicate a hydraulic system failure, requiring professional adjustment or repair. Ignoring this long-term can affect handling safety. Don't underestimate this warning signal—regular maintenance of steering components can save you a lot of money.
Hey, as a DIY car owner, I've found that low-speed turning noises can range from minor to serious. Common causes include worn universal joints on the steering shaft or loose power steering belts that creak when turning; aging and detached rubber bushings on suspension links that cause squeaking during turns; or foreign objects stuck in brake discs causing friction noises. These sounds are clearer at low speeds because the engine load is light, making them less likely to be drowned out. I recommend starting with a simple test: have a friend listen outside the car to roughly locate the noise; then check the color and level of the power steering fluid—if it's cloudy or low, it needs replacing. Avoid frequently turning the steering wheel to full lock to protect the system. From a safety perspective, don't delay repairs for too long—replacing a small part won't cost much. Pay attention to your car's smoothness in daily use, as unusual noises are often early warnings.
After years of repairing and modifying cars, I've found that most steering noises are caused by mechanical wear. A squealing sound at low speeds when turning is most commonly due to a faulty power steering pump or low fluid level, while a loose belt can produce a screeching noise. Worn suspension joints, such as ball joints, can create a clunking sound when turning, and aging wheel bearings often produce a low-frequency humming noise. The source of the noise provides clues: sounds near the steering wheel may indicate a steering column issue, while noises from the wheel area point to suspension or bearing problems. Simple checks include inspecting the power steering fluid level for low or contaminated fluid, and listening to the noise frequency – continuous clicking suggests loose components. It's advisable not to attempt DIY disassembly; instead, leave diagnosis and repairs to professional shops to ensure driving stability.
