What Causes Noise When Turning the Steering Wheel?
2 Answers
Possible causes of noise when turning the steering wheel include: 1. Turn signal: Sound from the turn signal rebound clip. 2. Steering column: Noise from the steering column dust cover. 3. Clock spring: Interference noise from the clock spring. Below is a detailed introduction: Sound from the turn signal rebound clip: If the noise occurs when turning the steering wheel after activating the turn signal, it may be due to the rebound clip of the turn signal auto-return mechanism. This sound is normal because the steering column has three return positions per full rotation. Turning the steering wheel will produce a clicking sound, and a full rotation will result in three clicks. This sound will not occur when the turn signal is turned off.
I've seen quite a few cars making strange noises when turning the steering wheel, which is mostly due to issues with the steering system or suspension components. For example, insufficient or dirty power steering fluid can cause the power steering pump to make louder noises when operating. Or, wear and tear at the ball joint or stabilizer bar connections can result in a rattling sound when the car turns. A faulty wheel bearing is also a common cause, producing a humming noise during turns. Additionally, insufficient lubrication of the gears inside the steering gear can lead to harsh screeching sounds. If these minor issues are not addressed promptly, they can evolve into safety hazards, such as sudden steering failure at high speeds. It's advisable to regularly check the power steering fluid and suspension components to ensure proper lubrication and prevent accelerated wear. Specifically, I once helped a friend fix a car where the noise was caused by loose wheel hub nuts—tightening them solved the problem. Remember, don't wait until the problem worsens to get it fixed; safety comes first.
