Why does he hit the steering wheel while driving or braking?

To my great regret, almost all car owners are sure that the vibration and beating of the rudder mean only the need for balancing the wheels. In fact, unbalanced wheels cause vibration on the steering wheel.

Vibration problems can literally derail themselves. And even more so - this malfunction has the property of sneaking up on an unsuspecting car owner unnoticed. And then one day, at some point, the rudder is already beating very hard, the vibrations are given to the entire body, the rudder is beating when driving and during braking. But the car owner has already got used to these vibrations and is in no hurry to STO for troubleshooting. Well, those who are faced with this problem and wish to understand it, should know the causes of these vibrations and beats on the steering wheel. In fact, there are a lot of different reasons. Knowing the reasons, you can easily eliminate the breakdown without significant costs and thus stop the vibration.

Diagnostic method

To conduct an accurate diagnosis, you need to operate the car in different modes. When driving along the track at different speeds, you need to feel when the rudder hits when driving (braking). Also it is necessary to remember, at what speed the vibrations begin and on what end. It is recommended to check how the machine behaves when accelerating and when braking - vanish or amplify the vibration.

Violation of balancing due to snow and mud

This is one of the most popular and most probable reasons why the steering is felt beating. Vibrations can suddenly appear and also stop after overclocking. It is very easy to see dirt on modern cast discs, and in the case of steel stamped ones it is already difficult. They have too small ventilation holes, and a decorative hood can significantly interfere with normal viewing. If you hit the steering wheel, you should look for dirt from the inside of the steel stamped disc.

Beats only at high speed: violation of balancing

Tires and rims are not ideal. They may be initially uneven or with a heterogeneous composition. Since the weight of tires and disks in places can be different, when rotating, it will pull to itself the center of gravity. This is a centrifugal force. When the wheel rotates at high speeds, this effort will necessarily be given through the traction to the steering wheel. To avoid such problems, it is necessary to perform wheel balancing after any replacement of disks or rubber. The essence of this process is to level the masses of the wheel at each point by means of weights that are glued to the inner or outer surface of the disk.

The operation of the car, on which the wheels have a bad balance, can provoke heavy wear in some places of the tire for a long time. As a result, the protector through 15-20 thousand kilometers of run will be "bitten off" in some places. Use such a tire or restore it makes no sense. The driver will feel that he hits the steering wheel even more when driving. Also with this wear elements of the suspension and the bearing of the hub. All this entails expensive repairs.

Symptoms of unbalanced wheels

The main features of tires with impaired balancing are, of course, strong vibrations when driving at high speeds. For passenger cars this speed is higher than 60 kilometers per hour. If the rudder hits hard when driving at speed, it is recommended to carefully inspect the wheels - they should not have dents and other deformations on their surface. If the car owner did not catch large pits while driving, the tires do not have much wear, and the vibration is only on the steering wheel at the time of acceleration, then most likely, the issue can be solved by simple balancing. However, do not think that you can solve the situation only by balancing the front wheels. The problem of vibrations can be won only if all four wheels are properly balanced.

Deformation of discs or tires

In some cases, if the rudder beats when driving, the reasons can be in curved wheels. This problem is easily identified by any qualified employee of a tire fitting shop after testing this wheel on the stand. He will definitely tell about it. It is important that the motorist himself was present during the test process and made sure that there is no problem.

However, if during the rotation, observing one point of the edge, it is clear that the wheel is jumping, this is the first sign. It should be determined whether the disk is jumping along with the tire. If so, the cause of the beats is the disk. If the latter does not jump, then the tire itself is damaged. Most of the discs bend due to falling into road pits. This often happens in the spring period of time. This can be determined even without the need to dismantle the wheel - it is enough to inspect the rim for dents. Particular care should be taken on the inside of the wheel. The most commonly used are steel stamped discs.

But not only dents can provoke vibrations. The wheel can be curved in itself - even on the stand it can rotate perfectly, and after installation on the car the owner will feel that his, for example, "Ford Focus" beats the steering wheel while driving. This phenomenon happens due to the fact that on the stand the wheel is fixed on the central hole, and on the car - through the holes for nuts or bolts. Sometimes they do not provide the maximum level of fastening. And the disc may not be even.

Worn or defective tires are also often the cause of beating on the steering wheel or vibrations throughout the body. Among the most common deformations are the damaged cord, bumps on the side walls, the manufacturer's marriage.

Insufficient level of pressure in the wheels

Sometimes, but quite rarely, the wheel rushes when driving a VAZ or any other car due to incorrect air pressure in the tire. This is one of the simplest reasons and it is very easy to diagnose it, and it is not difficult to eliminate it.

Dangerous Vibration

This fault is from a series of easily removable and easily diagnosed. Often hits the steering wheel when driving due to loose fasteners at least one of the wheels. The reason is actually very simple, but also very dangerous - if the wheel turns off, the result will be deplorable. As for car repair, it will be quite expensive. If this reason is not noticed on time, the car owner will come to replace the brake discs, wheel disks, hub elements. Vibrations in this case can occur at different speeds and even at very small ones, and the cyclicity of the beats is not always observed.

Steering links

Very often the steering wheel beats hard when driving (VAZ 2109 including) due to excessively worn out tips, as well as a strong development on the steering rods. To find out whether this is so, it is necessary to check the steering rods themselves for looseness. Then you need to ask the assistant to tightly grasp the steering wheel and pull up the steering wheel on the jack lifted by the jack - they should not have a free wheeling. If there is any backlash, or pulling and dangling altogether, this is the cause of the beats. The part needs to be replaced, and then - to make a break-down.

Steering Rack

Often beats the wheel while driving at any speed due to the heavily worn steering rack. If the wear is large, then the backlash of the steering wheel will increase. To eliminate this malfunction, it is recommended to press the clamping bolt on the rail. Tighten until the steering wheel returns to the middle position when turning. Then, loosen the bolt about one side. After this operation, the beating will decrease, or may completely disappear.

Ball bearings

This is one possible reason. First of all, you need to make sure that there is no play of the wheels on the ball joint. For diagnostics, the machine is lifted on the jack and the ball is supported on a static support that is on the ground. In this case, the wheel should be slightly in the air. Further one hand is taken for the wheel at the top, the other - at the bottom, and the wheel reel. If there is any play, then the ball bearing is worn out and needs to be replaced. After that, the vibrations can also stop. If they stayed, you need to look further.

If the wheel hits the brake when braking

When the car owner feels vibrations or beats only in the process of braking, then there is a great chance that the problem lies with deformations or any other problems with the brake drum / disc.

Both of the above elements change their shape or are deformed due to high wear or overheating when the driver brakes for a long time and is strong enough. Also, deformation occurs after a strong braking, and then falling into a puddle - the disk overheated and drastically cooled. After such tests, the surface of the part will take a wavy construction. The drum will change its shape to an oval shape. If you hit the wheel while driving (VAZ 2114 is no exception), then here is the reason for the rough exploitation of the car. Repair in this situation is impossible, and to fix the problem will only help replace worn or deformed parts.

Vibration and heartbeat on the "ten"

These cars are nothing special from other models and brands do not differ. If you hit the steering wheel while driving VAZ-2110, then the cause is the following malfunctions. Among them, one can distinguish brake pads, but this is very rare. And most often after replacing the pads the problem returns again. But to check their condition will not be superfluous.

Among non-standard reasons, the hub of vibrations may be a hub. In this case, it is recommended to punch it on the lathe or directly on the car with the help of special tools.

In addition, the cause of vibrations on the handlebars or the body may be the CV joint, which simply collapsed. In this case, the beats are felt during acceleration, and when the car is running down, the vibrations disappear. At low speed, they do not exist. In addition to beatings, strong noise can also be heard.

Summary

It must be remembered that a car is a one-piece mechanism where one malfunction can provoke a lot of other problems. If there is a beating on the steering wheel, you must immediately look for the cause and repair the malfunction. Riding with these vibrations is simply dangerous. As you can see, the problem is completely solved. The main thing is to notice symptoms in time and not to delay with their elimination.
