What Causes the Steering Wheel of Volvo S90 to Make Abnormal Noises When Turning?
1 Answers
Abnormal noises when turning the steering wheel may include sounds from the turn signal reset, noises from the steering column dust cover, sounds emanating from within the steering wheel, noises from the shock absorber plane bearing, or sounds from the stabilizer bar. Here are the specific details: 1. Sounds from the turn signal reset: If the turn signal is activated while turning, the noise might be from the rebound clip of the automatic turn signal reset mechanism. This situation requires confirmation. If it is indeed the case, then this is a normal occurrence. 2. Noises from the steering column dust cover: If the noise comes from below the steering wheel, it might be from the steering column dust cover. Due to insufficient lubrication of the dust cover, friction sounds can occur. In this case, applying some grease inside the dust cover will eliminate the noise. 3. Noises emanating from within the steering wheel If the noise comes from inside the steering wheel, the issue is most likely caused by the airbag clock spring inside. Remove the steering wheel airbag clock spring and apply some grease to see if the noise persists. If it still occurs, replace the airbag clock spring as it may be damaged. Be gentle when removing the steering wheel, or disconnect the airbag fuse to prevent the airbag from deploying. 4. Noises from the shock absorber plane bearing: If the noise originates outside the vehicle, it might be due to insufficient lubrication of the shock absorber plane bearing. Open the hood and listen to see if the noise is coming from the shock absorber top mount. This will confirm if the noise is from the plane bearing. Applying grease to the plane bearing may help. If the noise persists after greasing, replacement is necessary. 5. Noises from the stabilizer bar: If the noise is not from the shock absorber, check if the stabilizer bar bushings are loose or damaged. Loose or damaged stabilizer bar bushings can cause noises not only when turning the steering wheel but also when driving over uneven roads. Loose bushings can be fixed by adding shims, but damaged ones must be replaced.
