What Causes the Steering Wheel to Make Abnormal Noises When Turning Left or Right?
4 Answers
Under normal circumstances, there should be no abnormal noises when turning the steering wheel left or right while driving. However, issues such as problems with the power steering fluid, failure of the power steering pump, damage to the plane bearing, loose ball joints, or damaged dust covers can all cause abnormal noises when turning the steering wheel: Problems with the power steering fluid: If the fluid level in the reservoir is too low, air can enter the hydraulic system, forming airlocks in the oil pipes. This can lead to mechanical wear between steering components, resulting in abnormal noises. It is important to promptly add power steering fluid. Failure of the power steering pump: If the power steering pump emits a sharp noise, it indicates that the pump is damaged and needs replacement. Additionally, check if the drive belt of the power steering pump is slipping. If it is slipping, identify the cause and replace the belt or adjust its tension. Damage to the plane bearing: If abnormal noises occur when turning the steering wheel, it is recommended to inspect the dust cover of the front shock absorber. Apply lubricant to the top of the shock absorber. If the noise persists after applying lubricant, the plane bearing of the shock absorber is likely damaged and needs replacement. Loose ball joints: The tie rod ball joint is used for thrust steering during turns. If the ball joint is loose, it will produce abnormal noises when turning. In severe cases, the wheel may suddenly swing out or detach due to the ball joint coming loose. It is advisable to replace it promptly. Damaged dust covers: If the dust cover is cracked, dust and debris can enter the steering mechanism, causing abnormal noises. It is essential to replace the dust cover with a new one in a timely manner.
Steering wheel squeaking when turning left or right may be due to worn components or lack of lubrication in the steering system. With over a decade of driving experience, I've encountered this issue multiple times. The most common causes are loose tie rod ends or friction sounds from aged shock absorber top mounts. A noticeable squeak when turning the wheel, sometimes accompanied by slight wobbling, typically indicates these problems. Last year, my own car had similar symptoms - inspection revealed insufficient grease in the ball joints, which temporary improved after applying lubricant. However, prolonged neglect could lead to component failure, compromising driving safety. I recommend paying attention to these moving parts during routine maintenance, as proper lubrication prevents minor issues from escalating. The danger increases at highway speeds where steering failure risks multiply, so professional diagnosis with proper equipment should be sought immediately when noises occur. Avoid aggressive steering when stationary to minimize unnecessary stress and extend component lifespan.
A friend asked me about the cause of steering wheel noise, and I immediately thought it's most likely a chassis or suspension issue. Worn steering gear bearings, loose tie rod connections, or even lack of lubrication in the internal gears of the steering wheel can cause squeaking sounds. If you notice the noise occurs as you turn the steering wheel while driving, be cautious. If it only happens in cold weather, it might be due to aging rubber. I used to advise fellow car owners to check if the chassis bolts are loose themselves, but repairs require professional skills. Don't delay too long to avoid minor issues turning into major repairs. Regularly clean dust and mud from the steering area during car washes to keep components dry. Repair costs depend on the extent of damage—simple lubrication may cost a few dozen yuan, while replacing parts could run into hundreds, but it's a worthwhile investment for safety.
Steering wheel noise when turning is usually caused by mechanical friction, such as worn steering ball joints or damaged support bearings. If you hear a clunking sound when turning, it's time to take action. From my experience, uneven road surfaces can worsen the problem. Don't attempt DIY repairs—record the noise with your phone for a more accurate diagnosis by a mechanic. Safety first: stop immediately and check the condition of your tires.
