What Are the Causes of Abnormal Noises from the Car Steering Wheel?

Here are the specific causes of abnormal noises from the car steering wheel: 1. Faulty airbag clock spring. If the sound comes from inside the steering wheel, it may be caused by interference from the airbag clock spring inside the steering wheel. 2. Lack of oil in the shock absorber plane bearing. When turning the steering wheel, if the abnormal noise comes from outside the car, it may be due to a lack of oil in the shock absorber's plane bearing. If the shock absorber plane bearing lacks oil, applying some grease can solve the issue. 3. Loose stabilizer bar bushings. If the noise does not come from the shock absorber's plane bearing, check whether the stabilizer bar bushings are loose or damaged. Loose or damaged stabilizer bar bushings 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. 4. Dirty power steering fluid. If the power steering fluid is too dirty, it will increase the pressure in the power steering system, and the power steering fluid should be replaced promptly.
When there is an abnormal noise from the steering wheel, I often encounter this situation, which usually has various causes. Loose fixing screws on the steering column can cause creaking sounds, especially noticeable on bumpy roads. Worn ball joints or lack of lubrication in the steering system can produce squeaking noises when turning. Loose buttons or airbag modules on the steering wheel itself can also cause rattling sounds. Additionally, overheating of the power steering system components, such as the hydraulic pump or electric motor, may lead to a humming noise. Safety should not be overlooked; once abnormal noises persist, it is advisable to promptly check for loose screws, apply lubrication, or visit a repair shop to avoid the risk of steering failure at high speeds, which could lead to accidents. Both new and old cars require regular maintenance to extend the lifespan of their components.
