What Causes the Abnormal Noise When Turning the Steering Wheel While Stationary in a New Car?
2 Answers
New cars producing abnormal noises when turning the steering wheel while stationary can be attributed to sounds from the shock absorber top bearing, the stabilizer bar, the steering column dust cover, or interference from the clock spring. Noise from the shock absorber top bearing: If a noise occurs when gently shaking the steering wheel while stationary, it is likely due to insufficient lubrication in the shock absorber's top bearing. To confirm, open the hood and listen if the sound originates from the shock absorber's top mount. Applying grease to the top bearing may resolve the issue; if the noise persists, replacement is necessary. Noise from the stabilizer bar: If the noise is not from the shock absorber, check the stabilizer bar bushings for looseness or damage. Loose or damaged stabilizer bar bushings can cause noises not only when turning the steering wheel but also when driving on uneven roads. Loose bushings can be fixed by adding shims, while damaged ones require replacement. Noise from the steering column dust cover: Inspect the steering column dust cover. A lack of lubrication in the dust cover can cause dry friction noises. Applying grease inside the dust cover should eliminate the noise. Noise from clock spring interference: If the noise comes from within the steering wheel while turning, it may be due to interference from the clock spring. Remove the steering wheel and apply grease to the clock spring. If the noise continues, replacing the clock spring is the only solution.
Having driven for so many years myself, it's quite common for new cars to make strange noises when turning the steering wheel while stationary, mostly due to issues with the steering system. For example, the power steering pump might produce a "creaking" sound, especially when the hydraulic pump is idling under high pressure; it could also be that the steering tie rod or ball joint wasn’t tightened properly, a common oversight during new car assembly. Another possibility is loose suspension components, such as the shock absorber connection points, causing metal friction sounds. Additionally, new tires can make a rustling noise when grinding in place, particularly on rough road surfaces. I think this situation shouldn’t be ignored, especially since it’s a new car still under warranty. It’s advisable to check the source of the noise after parking, record a video, and then directly visit the 4S dealership for a free inspection. Also, try to avoid turning the steering wheel while stationary during normal driving to reduce the burden on the steering system and extend the lifespan of its components.
