What Causes Steering Wheel Shaking and Abnormal Noises?
2 Answers
The main reasons for steering wheel shaking accompanied by abnormal noises are as follows: 1. Noise from the shock absorber plane bearing: If a clunking sound occurs when lightly shaking the steering wheel while stationary, it is likely due to insufficient lubrication in the shock absorber's plane bearing. You can confirm this by opening the hood and listening to see if the sound originates from the shock absorber's top mount. If it is indeed the plane bearing, applying grease may resolve the issue. If the noise persists after greasing, replacement is necessary. 2. Noise from the stabilizer bar: If the sound does not come from the shock absorber, check whether 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 sometimes be fixed by adding shims, but damaged ones must be replaced. 3. Noise from the steering column dust cover: If the noise comes from below the steering wheel, it might be due to the steering column dust cover. Lack of lubrication in the dust cover can cause friction noises. Applying grease inside the dust cover should eliminate the noise. 4. Noise from inside the steering wheel: If the noise originates from within the steering wheel, it is most likely caused by the clock spring (airbag spiral cable). Remove the steering wheel airbag, apply grease to the clock spring, and check if the noise persists. If it does, the clock spring needs replacement. Be cautious when removing the steering wheel, or disconnect the airbag fuse to prevent accidental airbag deployment.
I was driving when I suddenly felt the steering wheel wobbling with strange noises—my heart skipped a beat! This is no minor issue! Common causes include loose components in the steering system, such as worn steering column joints, tie rods, or bearings, leading to the steering wheel shaking and producing creaking sounds. The noises may come from friction or damaged parts. If not repaired promptly, you could lose control during sharp turns—extremely dangerous. I once nearly had an accident on the highway and rushed to a repair shop for inspection, only to find that the linkage rod was broken. Replacing it fixed the issue. My advice: try shaking the steering wheel while parked to locate the noise source, and visit a professional shop as soon as possible. Don’t skimp on safety.
