What Causes Steering Wheel Noise in Cars?
2 Answers
Causes of steering wheel noise in cars include: friction between the steering column and floor mats, faulty clock spring, insufficient lubrication in the shock absorber's plain bearing, and loose stabilizer bar bushings. Below are detailed explanations: 1. Friction between the steering column and floor mats: If the noise comes from below the steering wheel, it may be due to oversized floor mats installed in the car that come into direct contact with the steering column. As the steering column rotates, friction occurs. If lubrication is lacking, this friction can produce noise, which can be resolved by applying lubricating oil. 2. Faulty clock spring: If the noise originates from inside the steering wheel, it might be due to a faulty clock spring inside the steering wheel. In this case, remove the clock spring from the steering wheel, apply grease, and observe if the noise persists. If the noise continues, the clock spring needs to be replaced. 3. Insufficient lubrication in the shock absorber's plain bearing: If the noise comes from outside the vehicle, it may be caused by insufficient lubrication in the shock absorber's plain bearing. Applying grease can resolve this issue. If the noise persists after lubrication, the plain bearing needs to be replaced. 4. Loose stabilizer bar bushings: If the noise does not originate from the shock absorber's plain bearing, check if the stabilizer bar bushings are loose or damaged. Loose or damaged stabilizer bar bushings can cause noise not only when turning the steering wheel but also when driving over uneven roads. This can be fixed by adding shims, but if the bushings are damaged, they need to be replaced.
I've been driving for decades and have encountered many situations with steering wheel noises. Usually, it's because the bearings inside the steering gear are worn out, causing a squeaking sound when turning, which becomes more noticeable over time. A loose steering column can also make the steering wheel wobble, producing a clicking noise. Issues with the suspension system's connecting rods or arms can transmit sounds to the steering wheel. If the power steering system is leaking oil or the belt is loose, the humming noise becomes more pronounced when turning. Don't underestimate these small noises—they often signal bigger problems. Ignoring them can lead to steering difficulties or loss of control, which is very dangerous. It's recommended to perform regular inspections and lubrication, such as getting a professional diagnosis every six months to prevent issues from escalating. Remember, safe driving comes first.
