What Causes the Abnormal Noise When Turning the Steering Wheel While Stationary in a New Car?
1 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.
