Why is there a strange noise when turning the steering wheel in place?
2 Answers
If there is a strange noise inside the car when turning the steering wheel, the following aspects should be mainly considered: 1. Sound from the turn signal rebound clip: If the noise occurs only when turning the steering wheel after the turn signal is turned on, it is usually the sound from the rebound clip of the turn signal auto-return mechanism, which is a normal sound. Following the direction of the turn signal, turning the steering wheel will produce a "click" sound, and three "click" sounds will occur when the steering wheel completes one full rotation. This is because there are three auto-return positions on the steering column, hence this sound. As long as the turn signal is turned off or the steering wheel returns to its original position and the turn signal switch resets, this sound will disappear. 2. Sound from the steering column dust cover: Whether turning the steering wheel in place or while driving, if the noise comes from below the steering wheel, the steering column dust cover should be checked. This is because the steering column dust cover can easily produce friction sounds due to lack of lubrication. The solution is simple: apply some grease inside the dust cover to help with lubrication, and the noise will disappear.
I just encountered this issue, and I suspect it might be related to the steering system. A common cause of strange noises when turning the steering wheel while stationary is a problem with the power steering pump, such as insufficient power steering fluid or a leak, which can cause the pump to squeal. It could also be due to worn gears inside the steering gear or aging power steering lines. Another potential issue is with suspension components, like loose shock absorber mounts or ball joints, which can make noise under the heavy load when turning the wheel while stationary. Check the power steering fluid reservoir level—if it's low, top it up and see if that helps. If not, it's best to have a professional take a look. Safety-wise, don't underestimate this noise; if left unchecked, it could lead to steering failure, which would be a serious problem. Regular maintenance, like changing the power steering fluid periodically, can help prevent such issues.
