Discovering abnormalities in the steering wheel involves the following phenomena and causes: 1. Abnormal noise after turning on the turn signal. Fault phenomenon: Normally, there should be no abnormal noise when the turn signal is activated. If you hear a faint "click, click" sound under the steering wheel, it indicates an issue. Cause analysis: Since the abnormal noise occurs after the turn signal is turned on, it is necessary to analyze whether the noise is related to the turn signal switch. After removing the steering wheel and activating the turn signal, it was found that the return mechanism of the turn signal switch was faulty, causing conflict between the steering wheel and the switch return device during steering, resulting in the noise. 2. Impact on left and right wheels, abnormal noise from the front wheels. Fault phenomenon: When impacting left or right, abnormal noises such as "squeaking" or "grinding" are heard from the upper part of the front wheels. The noise is related to changes in the steering angle. Cause analysis: When the front wheels turn left or right, the rotating part involves the strut bearing at the top of the shock absorber spring. Typically, after such abnormal noise occurs, it indicates abnormal wear of the bearing at the top of the shock absorber, leading to the noise.

I often drive and notice that steering wheel abnormalities mostly reveal themselves during high-speed driving. For example, holding the steering wheel feels like it's constantly shaking, similar to a phone vibrating, which is often caused by tire imbalance or wear. At low speeds, if turning the steering wheel feels heavy and laborious or there's too much free play, with the wheels responding sluggishly, it indicates potential issues with the power steering system. After parking, I usually give the steering wheel a simple shake to check for play: if there's noticeable looseness or squeaking noises, it's likely due to loose connecting components. These signs should not be taken lightly. Once detected, I arrange for repairs as soon as possible to prevent worsening conditions that could lead to steering failure or accidents. It's all about driving safety—don't delay handling it to save money.

Through daily driving experiences, I can detect steering wheel issues using simple methods. First, start the vehicle and gently turn the steering wheel while stationary to listen for sounds—if there's squeaking or clicking, it indicates internal component wear. While driving, observe if the vehicle consistently pulls to the right or left, especially on flat roads, by firmly holding the steering wheel to sense any drifting tendency. If the steering wheel vibrates excessively on bumpy roads, it may stem from wheel hub or suspension faults. After parking, check the power steering fluid level and lightly shake the steering wheel to inspect for excessive play. These steps help identify potential issues early, preventing costly repairs. Timely maintenance ensures efficient steering system operation.

As an ordinary driver, I pay close attention to every change in the steering wheel's feedback. When driving on city roads, if there's any delay in steering response or misalignment before turning, I immediately become alert. Or if the steering wheel develops slight involuntary vibrations during straight-line driving accompanied by unusual humming noises, it often indicates balance system issues. I'll stop to check by gently shaking the wheel for excessive play, though these symptoms usually stem from daily wear and tear. Neglecting such details may compromise turning safety, so I always prioritize professional inspections for peace of mind.
