Rubber creaking when turning the steering wheel in place - Skoda, Logan, Priora, Volkswagen

To change the direction of movement in the car, steering is provided . It consists of a rudder and a shaft that enters the mechanism connected to the trapezium. The last detail on most cars consists of a rail and outgoing from it to the wheels of long and short rod with hinges.

Varieties

To simplify the rotation of the steering wheel on modern cars installed amplifier. It can be of different types:

1) Hydraulic.

2) Electrical.

3) Electrohydraulic.

The hydraulic amplifier works on the strength of the special fluid that the pump pumps. The second mechanism works from the electric motor. And the third type contains elements of a hydraulic and electric amplifier. Each such type has a complex design, has its own advantages and requires different maintenance and operation.

Symptoms of control failure

With the increase in wear and tear on the parts of the steering control of the car when the steering wheel is turned on the spot, a squeak is heard, and various kinds of foreign knocking occur, with time increasing. They entail a malfunction or a complete refusal to work. The signs of a malfunction of this control include knocks in the steering gear, a rail, a tip or links. There is a creak when turning the handlebar in place and extraneous noise in motion. As a result, the machine does not listen well, loses stability on the road. While driving, the car can be carried away. Before you begin to eliminate a particular control malfunction, you need to understand why this can happen. The most common problem is a strong creak when turning the steering wheel in place. Most drivers do not know the cause of this malfunction, and at the same time they can manually disassemble the whole trapezium without specifying what the snag is, in fact. Therefore, depending on the device steering system, creaking when turning the steering wheel in place can occur for various reasons. It happens that the malfunction is not even in the steering trapezoid.

Squeak when turning without an amplifier

On cars "Dacia" and "Renault Logan" in the basic configuration does not provide the presence of an amplifier. Therefore, squeaks when turning the handlebar in place (Logan 1.6 including) may occur due to breakdown of the front suspension spring, wear of the bearing of the upper support of the telescopic pillar, or due to the wear of the rubber pillar of the pillar support. With a strong wear, and especially when the development is uneven, it begins to squeeze out. Hence, a rubber squeal arises when the steering wheel is turned in place.

Sounds on the car with hydraulic booster

The steering mechanism with the hydraulic booster consists of the same parts and trapezoids, only in the rail there are special oil channels. Through them, oil under pressure acts on the steering rods, which facilitates the rotation of the wheels. On WAG vehicles such as Skoda, a hydraulic amplifier is installed, and creaking when turning the steering wheel in place can occur not only due to the wear of the bearing with the rubber cushion of the upper pillar support or the spring. It may be the wear of the components of the power steering pump and its drive. There are the following reasons for the long-term exploitation of the creaking when turning the steering wheel in place (Skoda, among others):

- wear of the impeller of the power steering pump;

- wedging of the power steering pump;

- wear of the belt;

- pierced anthers in the steering rack (it will start to flow);

- wear of the drive pulley of the pump of the amplifier.

This trouble happens, even when the steering is working properly. In a strong reversal in place of the wheels, the load on the power-steering pump becomes large. Especially when the car is loaded. Sound occurs due to increased wear of the drive pulley or belt. In this case, the belt slips and creates such a noise. It's quite easy to make sure of this - you just need to pour some water on the pulley. The liquid will play the role of lubricant, and if the squeak disappears, it means that it is in the pulley or belt. Squeaking when turning the steering wheel in place ("Volkswagen-Polo") occurs for the same reasons as on "Skoda", as they are cars of the WAG concern.

Problems with the electric booster

Unlike hydraulic steering, the rotation of the wheels facilitates the motor. It is connected to the steering gear by a belt drive. On vehicles VAZ-2127 is installed control with an electric amplifier. Squeak when turning the steering wheel in place ("Priora" including) is possible for the following reasons:

- wear of the belt;

- wear of the pulley of the electric motor and steering gear;

- low voltage in the network;

- lack of "mass" of the car;

- malfunction of the electrical control unit.

Breakdowns

In addition to the wear of the pulley and the belt that connects the motor to the mechanism, it is also possible to creak when turning the handlebar in place due to a breakdown of the wire leading to the motor. Since it is difficult to turn the wheels in place, the electric motor is loaded, and with a weak battery it will not be possible to reach the required power. In this case, the battery is filled with electrolyte or the battery is completely replaced. Also, a weak charge in the battery can occur due to a poor current from the generator. Therefore, it is worth checking it for service and "ringing" the wires so that there is no unnecessary loss of electricity.

Eliminating extraneous sound

To eliminate the scratch when turning the rudder in place, first you need to determine the cause of extraneous sounds. On vehicles with power steering, if the system is malfunctioning, the "check" will light up on the instrument panel. Therefore, the driver should diagnose his car for errors. Special software at the service station will show where the disruption occurs and which sensor is out of order. When the cause is found, proceed to repair. If the problem is in the suspension, the damaged and worn out parts are replaced with new ones. In the steering with power steering replace the worn belt or pulley, check the serviceability of the pump and change the oil as needed. If the power steering pump is faulty, it is replaced with a new one. In vehicles with electric drive, check the integrity of the wires of the electric motor and generator. The generator's working capacity and the condition of the belt pulley are also diagnosed. Defective and worn out parts are replaced with new ones. To the steering with electrohydraulic booster apply the same measures as for individual types of steering. And since the system here is rather complicated and confusing, it will take more time and patience.

Service

In order for the steering to function properly, the driver must know how to properly service and operate it. To do this, carry out maintenance: replace the oil in the power steering pump, wear out the tips or steering rods, replace them with new ones, check the alignment of the wheels and adjust the angles when the corners do not match. Spare parts and oil should be from quality and original manufacturers. In the course of operation, the driver must monitor the condition of the steering, the operation of the hydraulic or electric amplifier. Also in the hydraulic system there should be no air. This will ensure a moderate load on the pump of the device. Check the tightening of bolts in the connections of the steering trapezoid or the attachment of the steering mechanism to the body, as well as the tightening of the motor or pump. If there is a big play on the rack, it can be twisted. But try not to overdo it. As a result, even with a hydraulic booster you will have a tight and uncomfortable control. While standing still, it is not recommended to turn the wheels out. Turn them not to the limit. This will lessen the load on the steering rack, the drive belt with pulleys, the power steering pump or the electric motor. Also, having turned on a place of a wheel of the car, it is not necessary sharply to touch and give in to turns of the engine. This greatly accelerates the wear of the steering parts. In addition, the service life of the hinges of equal angular speeds will be shortened, in case the car is front-wheel drive. If a cardan gear is used in the mechanism, it is recommended to lubricate the joint places periodically. It is produced by the method of syringing. Universal lubricant "Litol" is used. It can be used for squeezing car pivots, if an independent beam is used in the design from the front.

Conclusion

Proceeding from this, it is necessary to emphasize that the correct operation of the steering depends primarily on the driver. From the way he serves the mechanism, monitors his condition and exploits, his serviceability depends. Therefore, it is important to take care of the steering, take care of it for serviceability, maintain it in accordance with the maintenance book and repair it using only high-quality spare parts. Following these rules, the driver will ensure the long-lasting operation of the steering control of his car, which will give good control during the movement and its safety.
