Why vibrates the steering wheel when braking and at speed

14.04.2021

An unpleasant feeling covered you when the steering wheel is literally escaping from the hands, begins, as you think, belessly and uncontrolled. But this is not the case, the beating of the steering wheel at the time of braking and at speed is only a consequence, and not the true reason. There are only few of them. The main is the wrong operation of the machine nodes, due to which the beating through the suspension is transmitted to the steering wheel. If it does not get rid of it, the consequences will be serious, representing a danger to life.

Steering Wheel Vibration at Speed

The main cause of beating at speeds is associated with wheels, discs and anterior hub. This is primarily the dismantling of the wheels. The vibration begins, as a rule, at a speed of 90 km / h and almost ends with acceleration to 120. It means that at high speed, balancing weights are shifted and self-centering occurs, but with a decrease in speed, the beating increases again.

Such a process can be compared with the work of the washing machine. Folding into the drum of the machine lingerie unevenly, we create conditions for strong vibration at the beginning of the promotion. By typing the speed and aligning the center of gravity using a centrifugal force, the centrifuge continues to spin calmly without beating. Mass linen inside self-string. The same happens with our wheel. This wheel must be given to the tire-commercial workshop so that the specialists will be balanced.

Wheel unbalance can occur due to elementary dirt that fell on it and dried in separate places. To do this, you just need to clean the disk from the dirt.

Wheel vibration can cause a bus defect. The tire, which observes deformation or great wear is the explicit cause of the steering wheel.

The most common defects are the following:

  • rip metal strip (cord) inside the tire. In this part of the tire there is a characteristic convexity;
  • if you get into the Colds, in pits with sharp edges and driving through the rails, swollen or cones are on board tires;
  • tires with a factory marriage, which is visible to the unarmed look.

Often, the beating of the steering wheel comes from elementary inattention, when the wheel is not sufficiently fixed. Most likely, the driver did not delay as follows the mounting bolts. Stamped discs made of steel do not withstand a strong blow and there is a violation of its geometry. Damage to the wheels in this way, the cause of the steering wheel is caused. As a result of the strike, it is deformed, as a rule, only the edge of the disk. Forged discs hold well and least exposed deformation. You can eliminate such a problem with the restoration machine for rolling disks.

You can create a problem with vibration by putting unsuitable discs that are incompatible with the machine parameters of the machine. Suspended system nodes in this case are subjected to additional loads. The parts are wearing much faster, the backlats increase in the landing sockets and the steering wheel vibration begins.

Sometimes the wheel vibration occurs when the speed is set. In this case, the deformed hub is to blame, which became as a result of the strike. Suspension wear occurs similar use of unsuitable disks.

The beating of the steering wheel at a speed of over 90 km / h on the rear-wheel drives most often arises from the wrong balancing of the cardan shaft. When replacing the crossings, the order of their installation is confused, which leads to unbalanced and vibration. To eliminate this reason, you need to rotate the cardan shaft in the fastening places until the beating disappears.

The next cause of vibration at the speed-related speed can be the backlash of a small kardanchik, located under the casing in a place where the steering column enters the machine body. Try to pesame this cardan and feeling the backlash, remove it. Then, breaking this node, you look at the damage on it, which is the true cause of the fighting of the steering wheel at speed. Install a new drive steering knot, and the steering vibration will disappear.

Vibration of the steering wheel when braking

Such a problem is related to the elements of the brake system. The simplest and most common cause is a dirt that fell on the brake disc and dried there. You need to remove the caliper and clean it and the disk from the dirt, at the same time all the nodes are near.

Another reason for the occurrence of the vibration of the steering wheel when braking is when the disk and brake pads are wearing not always evenly. When the disk wear is unevenly, there are grooves and furrows appear on it, which do not allow the friction part of the pads to the disk mirror tightly. As a result, vibration appears. You can pump the disc, if its thickness allows, but it is much easier to replace everything in the complex, without comprehensive costs.

The occurrence of the steering wheel can help the sand, which fell into a disk or poor-quality friction pad pad, giving a lot of abrasive material when braking. When the disk thickness is suitable for the boundary size of the sizes, then it will behave from overheating during the braking process, the geometry will be impaired and the beating will arise, which will destroy the brake pads. At the same time, the friction part of the brake pad is fluent in the metal frame and the steering wheel vibration occurs.

Such a free chat can lead to the removal of the entire brake pad and the disk jamming, which is fraught with an emergency.

Attention! Fast finding the cause of the beating of the steering wheel when braking is the key to your safety.

Vibration steering wheel on turns, uneven road and idling

If you have noticed the steering wheel when performing turning, you can say with confidence that shruses or silent blocks are to blame. Replacing these parts The process is quite laborious, but the output is only one - you need to change urgently.

When replacing the shrurs, carefully check the status of the front hub bearings.

The very common cause of the beating of the steering wheel on the irregularities of the road surface is a notable tire pressure difference. The difference in pressure is allowed not more than half an atmosphere, if it is more, it becomes very difficult to manage the machine. Do not be lazy, carefully read the instructions, it is indicated which optimal pressure should be in tires with different loading. Hence the conclusion: before each departure it is necessary to check the pressure in the wheels.

Tip! Before each departure, be sure to check the pressure in all wheels.

When malfunctions in shock absorbers, when you pass the rotation at speed, it is noticeable how the steering wheel vibrates. The reason can be the extension rubber bushings and leakage of fluid from these nodes. It's time to put new shock absorbers.

Steering rack, or rather, its wear leads to the appearance of vibration on the steering wheel. The free strength of the steering wheel increases markedly and accounts for the rush part to press the bolt for adjustment. It is necessary to delay it until the moment that does not allow it to go to the neutral position. In this case, the vibration decreases, but does not disappear and the gap on the steering rake is gradually increasing on its impact. Output one - replacement of this node.

When the engine is running on idling turnover, the steering beating may occur due to strong wear of the airbag mounting of the motor and gearbox. The work on the replacement of these parts does not represent.

Cleaning or bad conditioner balancing may well cause steering wheel vibration. When the air conditioner fan always supports the maximum speed, it means that the radiator is strongly contaminated or even clogged. This mode of operation of the fan contributes to the appearance of the steering wheel. To eliminate the vibration, it is necessary to clean the air conditioner radiator, and it is only better to do on the car service.

The beating of the steering wheel may appear when malfunctions in the ignition system, and it is very noticeable when the engine is "Troje". The ignition system is a complex node, and it should not be joking with it. In this case, you need to replace the candles and pass the engine diagnosis.

Another interesting point when turning the steering wheel in place when the engine is running, vibration at idle can also occur. This happens when driving steering and tips or when weakening their tightening. Check out the steering thrust with the helper: it holds the steering wheel, and you are checking their free move on a subdomain car.

When the production in the steering rods is large and they are free to dangle, the steering wheel vibration occurs. During movement, it can lead to the separation of the ruling system traction and make the car uncontrollable that even at low speed will create an emergency situation. Replacing the power steering and tips, be sure to work to install the correct convergence and collapse.

Tip! Before any trip, check the tightening of steering and tips.

Big generation of ball supports also leads to the occurrence of vibration on the steering wheel. To check, lift on the jack completely the wheel, install the car on the reliable and stable support and lower the jack. One hand take over the top of the wheels, keep the other hand. Rash the wheel along the beam. If the node is generating, then you immediately feel the back. Such a support must be changed.

All car owners are tormented by the question, what does the vibration mean and what is its causes? However, whatever reasons - the beating of the steering wheel, the phenomenon coming out of a number of normal. This is alarm signal that sends us a car. To postpone the trip to the diagnostic center and the subsequent repair of the machine can not be in any way, otherwise you risk a car and your health.
