What causes abnormal noise when turning the steering wheel of a car?
2 Answers
The abnormal noise from the car's steering wheel can be attributed to three main reasons: 1. Friction noise from the steering wheel horn electrode: This is common in cars without airbags and only a horn button on the steering wheel. Since the horn switch rotates with the steering wheel while the connecting wire beneath it remains stationary, the wire can easily break when turning the steering wheel if it's still connected by wires. 2. Excessive play in the universal drive assembly: There is a universal joint at the front end of the steering column. Lack of lubrication or increased play in the universal joint can cause abnormal noise, requiring lubrication of the universal joint. 3. Noise from the steering wheel return lever: The turn signal has an automatic return function. When the turn signal is on and the steering wheel is turned, the steering column hitting the return lever produces noise, which is not a malfunction.
I've been driving for many years and have encountered steering wheel noises several times, which is quite annoying. The most common issue is insufficient or dirty power steering fluid, causing the power steering pump to squeak. It's crucial to add new fluid or replace it immediately. Another possibility is dust or wear inside the steering column, especially after driving on bumpy roads, producing a grinding sound. If the belt is loose or worn out, it can also cause a creaking noise when turning. Sometimes, chassis components like the steering knuckle may loosen, requiring tightening of the screws. Ignoring these issues can lead to steering failure, which is extremely dangerous. I always recommend checking the fluid and chassis first before considering part replacements—don't delay.
