Beating on the steering wheel at speed: possible causes and solutions to the problem

A long road tires everyone, and the driverespecially. With such a situation as the beating on the steering wheel at a speed that lasts a long time, many drivers came across. It is worth noting that the vibration of the car can be natural, and there are no prerequisites to worry. To such cases, uneven road surfaces are considered. In other cases, on an even surface, the presence of extraneous vibrations is an alarming signal, indicating a malfunction.

If you ignore the appearance of vibration, thenyou can seriously pay in the future not only for expensive repairs. At moments of vibration, special attention is paid to the steering wheel, its imbalance. Most often, the beating on the steering wheel at a speed arises from the lack of balance of the wheels, but this is not the only reason. There are many reasons for the vibration of the steering wheel, to determine which it is necessary to test the car on the track, periodically switching from one transmission to another.

The main causes of vibration of the wheel

When there are knocking on the steering wheel, rememberthe speed at which this happened. Then you should diagnose the car on the go and set the speed mode, at which the vibration disappears. Very often, the beating manifests itself during driving at low speeds and at medium revs, while the steering wheel beats quite unpleasantly. But if the driver slightly increases the speed, then the vibration ceases to manifest. Perhaps its repeated manifestation during a sharp acceleration.

When testing your car, you shouldLook at the manifestation of shaking during a sharp braking or with acceleration. It is necessary to view the vibration strength during the diagnosis. The reasons for the rudder's beating at speed are varied.

Improper balancing due to foreign matter

The most common reason for beating on the steering wheelis the presence of foreign matter on the inside of the wheel. That is why there is a violation of the balancing of the wheels, because of what the machine on the track starts to vibrate at different speeds. If there is dirt on the discs, and the road is uneven, then after a while the runout may stop due to the self-falling off of the clumps of dirt. However, in the presence of knocking, it is better to stop and look at the disks. If there is dirt, it is better to remove it with a special metal brush. The easiest way to determine the presence of it in cast discs, on stamped same wheels, such an inspection without removal will be very difficult. In this case, you need an overpass or a ski lift. Similarly, snow acts on the wheels, which clogs the discs on the inside as tightly as possible, which affects the vibration.

Lack of wheel balancing

The wheel disks are made uneven in shapeand the composition, because of which each region has different masses. The center is drawn to the side where the largest mass is located. As soon as the center shift occurs, the centrifugal force also shifts. As a result, the steering wheel is beating at speed because of the available transmitted forces along the chain of links at high speeds.

That is why it is necessary to producebalancing of wheels after each replacement of tires or disks. Balancing is the process by which the mass of the wheel is aligned throughout the contour using special elements, popularly known as "weights". They are glued or clogged to the wheel disc on the inside.

Natural wear of tires

When the vehicle is operated for a long timemeans with improperly balanced wheels there will be a rapid wear of the tires at some points, which subsequently leads to a strong vibration. In addition to the wear of the rubber, the pressure will increase when working on the bearing of the hub and some elements of the suspension, which will increase the beating on the steering wheel at speed.

Determining the disturbed balancing is quite easy. When driving at high speeds, a weak vibration appears. On the example of cars, the speed should be at least 60 km / h. Visually the wheels will be intact, there will be no deformation marks on the tires and disks.

Deformation of wheels

The degree of its development has a strong influence on thepresence of vibration. The deformation of the wheels occurs when the disc enters the pit at high speed. Curvature of the wheel can be determined by visual inspection: if the disk fell into the pit and has deformation in some places, dents will be observed on the rim of the wheel. In most cases, the front of the disc is deformed less often than the inner side. Among cast and steel wheels, deformation is inherent in the latter. Sometimes the disc is curved from the moment of its purchase. Check the curvature of it can be on a special stand for wheel balancing, which is available in any tire shop. If the wheel will be walking the figure-eight, then it will tell about the presence of a strong deformation or curvature from the moment of manufacturing. Because of this, not only does the steering wheel vibrate. It is transmitted over the entire suspension, and then spreads around the body.

When worn or deformedtires will be observed beating the rudder at a speed of 120 km / h. In this case, not only the beating of the rudder, but also the vibration of the machine, which depends on the degree of wear, can take place. The only way out of this situation is a complete replacement of disks or tires.

Insufficient tire pressure

If there is insufficient pressure in the wheels, then vibration will begin to occur throughout the vehicle (less often it goes to the steering wheel). After you have pumped the tires, you can solve the existing problems with vibration.

Weak wheel fastening

Running at low speed can be observedwith a weak fastening of the discs to the hub. If there is a strong vibration at the beginning of the movement, you must stop immediately and make a visual inspection of the fixing bolts.

As a rule, some of them can calmlytwist your hand. However, if they do not scroll, you need to take the balloon wrench and tighten the bolts. Otherwise, ignoring the situation will lead to a simple unscrewing of the wheel from the drum, which can cause an accident. At low speeds, it will not be so dangerous, but still you should not bring the car to such a state. Also acyclic, that is non-constant beating of a rudder at different speeds can be observed.

Malfunction of a suspension bracket or a steering system

There are other reasons whythere is a beating on the steering wheel at speed due to untimely maintenance of the vehicle. The disabled suspension strongly affects the grip of the car with the road. In the presence of play in the suspension elements or steering system during the rotation, the same vibrations will occur as with the use of bent wheels. This reason is indirect.

Runaway when braking at speed

This is a very serious malfunction. If there is a ripple at high speed at the moment of braking, this is the main sign of wear of the brake discs. This indicates that the discs or drums have traces of deformation, that is, the surface will be wavy. It can be caused by a long period of operation or by overheating of the drum or disc during sudden braking.

If there is a deformation of the drum or disc, thenvibration will be observed only during braking, when pressing the pads on the disc. Solving the problem can only be done by replacing these elements with new ones.

Running in the corners

When driving, beating on the steering wheel at a speed canmanifest themselves during the turn. In this case, you can safely say about the need for a diagnosis with a subsequent replacement of the suspension, because the failure came out the joints or silentblock. When turning, in addition to shaking, you will hear a characteristic crunch from under the wheels. When carrying out the replacement of the CV joint, it is necessary to check the efficiency of the bearing of the hub and, if a large workpiece is found, replace it. To prevent vibration when cornering, you need to conduct periodic inspections at the service station. When self-inspection of the car on the pit, the first sign of the approaching vibration is a crack on the anthers. Replace them with grease filling.

When driving on an uneven road, runoutindicates a violation of the steering rack. A lever bushing can break out. Also on the beating on the steering wheel is affected by a failed shock absorber. Thus, there are many reasons that cause a beating on the steering wheel while driving. In each case, the first thing to do is to perform a visual inspection and repair the malfunction.

So, we found out the reason for the rudder beating at high speed and when braking.
