What Causes the Squeaky Electric Current Sound from the Steering Wheel?
2 Answers
Steering wheel electric current squeaky sound is caused by a faulty indoor temperature sensor. Steering wheel issues: If the abnormal sound comes from inside the steering wheel, the problem is most likely due to the airbag clock spring inside the steering wheel. Remove the steering wheel airbag clock spring and apply some grease to see if the noise persists. If it still squeaks, replace the airbag clock spring. Be gentle when removing the steering wheel, or disconnect the airbag fuse to prevent the airbag from deploying. Stabilizer bar issues: If the sound is not coming from the shock absorber, check whether the stabilizer bar bushings are loose or damaged. Loose or damaged stabilizer bar bushings will not only cause noise when turning the steering wheel but also produce sounds when driving on uneven roads. Loose stabilizer bar bushings can be fixed by adding shims, but if they are damaged, they must be replaced.
I've been driving for many years and have encountered the squeaky electric current sound from the steering wheel several times, with many possible causes. The most common issue is a problem with the motor or sensor of the electric power steering system, possibly due to wear and tear or aging leading to poor contact. If the sound is particularly noticeable during turns, it might be that the steering column bearings need lubrication—dryness can cause squeaking. Additionally, short circuits in the wiring or loose connectors can also produce an electric current sound, which is more common in older vehicles. Ignoring such noises may result in weakened power steering and a higher risk of losing control during high-speed turns, posing a safety threat. I recommend taking the car to a professional repair shop for diagnosis and repair as soon as possible, and avoid tampering with electronic components yourself. Regular maintenance and keeping the system clean can prevent many issues.
