When the vehicle is malfunctioning, it is possible to hear some noise when turning the steering wheel. Detecting these sounds, recognizing them and acting accordingly is important to prevent further damage and safety issues.
Steering system by car
The car steering system is a system that rotates the front wheels in order to steer and control the car. Through the steering wheel, the driver is able to move the wheels.
The control system is one of the main elements of the car security system, and, ideally, the address should be soft and transmit accurate tactile information and a sense of security to the driver.
Currently, there are three types of power steering: hydraulic, electro-hydraulic and electric.
Malfunctions in the steering system are usually associated with the deterioration of certain components, a malfunction in the hydraulics, or external factors.
When the control system is faulty or does not work correctly, a number of noise may occur when the steering wheel is turned, which clearly show the type of malfunction.
Most characteristic steering wheel noise and their causes
Finding and eliminating noise when turning the steering wheel can be a daunting task, even for a professional workshop. Below, the most characteristic noises when turning the steering wheel, and the possible causes and malfunctions that cause:
- Growl when turning the steering wheel. It is possible that this effect is due to a too low level in the liquid. A pump is a component charged with creating pressure in a hydraulic system. If there is not enough fluid in the circuit, the pump, as a rule, generates air bubbles and a set of gears located in its internal part - it makes a crack when it is activated.
This noise when turning the steering wheel can also occur when air enters the pump due to lack of tightness in the track (damage, cracks, etc.).
- Click when turning the steering wheel. The click is due to the airbag. In this case, you may notice electronic problems (for example, problems in the steering angle sensor).
- Vibration when turning the steering wheel. If a little vibration is transmitted by the steering wheel and it takes more effort than usual to manipulate the steering wheel, then this is probably due to a breakdown of the pump or steering damper. In this situation, there is a lack of accuracy when turning the steering wheel.
- The sound of the steering wheel. If there is a knock, and, as a result, noise when turning the steering wheel, there is a possibility that the support of the wishbones is in poor condition.
- Crunch when turning the steering wheel. A problem in the ball can lead to poor handling. This can lead to crunches when turning the steering wheel. In addition, this situation gives the driver a feeling of lack of accuracy in the direction of the car, which forces you to adjust the trajectory of the car.
- Crackles when turning the steering wheel. There is a chance of crackles inside the box. These noises when turning the steering wheel, as a rule, arise due to wear of the internal seals.
- Squeak when you press the steering wheel on both sides. Maybe because some axis or CV joint are in poor condition.
- A rumble when turning the steering wheel. Turning the steering wheel may be accompanied by a thud from the area of the front shock absorbers. This situation indicates a possible anomaly in the cups of the shock absorbers of the front wheels.
- Noise when turning. When making a turn, you can hear a specific noise. This noise is often caused by asymmetric tire wear.
- Friction when turning the steering wheel. Sometimes, friction can occur when turning the steering wheel, because the gasket mounted on the panel does not contain proper lubrication.
- Clack noise when steering the steering wheel. not original bushings.
- Knock when you press the steering wheel. There is a possibility of such a noise when you press the steering wheel in both directions. It occurs due to the fault of the protective casing behind the steering wheel.
Some of the most important tips to avoid steering wheel noise are:
- Check and correct, if necessary, steering fluid level. When filling with liquid, it is advisable to ensure its cleanliness, in accordance with the manufacturer's recommendations, to prevent foreign particles from entering the circuit.
- Check for leaks along the chain. Particular attention must be paid to the junction of the surfaces of the switching elements.
- Monitoring and lubrication of steering elements (sliding bearings, flywheel, half shafts, rollers, etc.).
Many of the noises are directly related to car safety. Improving road safety is crucial, therefore, it is very important to comply with the terms and regulations of preventive work recommended by the manufacturer.
