What Causes the Steering Wheel to Make Noise at Low Speeds?
2 Answers
The causes of noise when turning the steering wheel at low speeds include the sound from the turn signal return mechanism, noise from the steering column dust cover, and noise from the shock absorber thrust bearing. Below are the specific reasons: Sound from the turn signal return mechanism: If the turn signal is activated while turning, the noise may come from the return clip of the automatic turn signal reset mechanism. The driver should confirm this. If it is indeed the case, this is a normal occurrence. Noise from the steering column dust cover: If the noise comes from below the steering wheel, it is likely caused by the steering column dust cover. Due to insufficient lubrication in the dust cover, friction noise may occur. In this case, applying some grease inside the dust cover will eliminate the noise. Noise from the shock absorber thrust bearing: If the noise originates outside the vehicle, it may be due to insufficient lubrication in the shock absorber thrust bearing. Open the hood and listen to determine if the noise comes from the top mount of the shock absorber. If so, the thrust bearing is the source. Applying grease to the thrust bearing may resolve the issue. If the noise persists, the thrust bearing will need replacement.
I've encountered the issue of strange noises when turning the steering wheel at low speeds several times. The most common cause is the power steering system, such as an aging or low-fluid power steering pump, which can produce squeaking sounds during operation. Another frequent reason is wear and tear on the steering linkage and ball joints; cracked rubber bushings can lead to a rumbling noise at low speeds. Insufficient tire pressure or uneven tire wear might also cause friction with the wheel arch during steering, resulting in noise. In my previous car, the noise was caused by a power steering fluid leak, which was resolved after a check-up at the shop. Ignoring such issues can lead to increased wear over time and even loss of steering control, especially dangerous on curves. Therefore, don't delay—check the power steering fluid level and steering components as soon as you hear any noise. If there's a problem, get it fixed immediately. Safety first.
