Vibration at a speed of 100-120 km / h: the main causes

Any driver is greatly alarmed by the situation,when there is a vibration at a speed of 100-120 km / h on the steering wheel or on the body. And it's not just a matter of uncomfortable feelings, although it needs to be said, these symptoms are a rather unpleasant phenomenon. If you do not take corrective measures in time, this can lead to a violation of the body geometry. This will not happen immediately, but slowly and gradually.

Distortions can trigger a violationaerodynamic characteristics, as well as deterioration of the car's handling. In addition, due to vibrations in the metal, cracks can form, which is not only dangerous in itself, but also requires expensive repairs.

And that's not the whole problem. If the machine is vibrating at a speed of 100-120 (VAZ 2110 is no exception), this leads to the unwinding of various fasteners. This phenomenon can lead to serious consequences - these are accidents, as well as various malfunctions and damages, which will be very difficult to eliminate. It is worth adding that this kind of shaking is a signal of breakdowns, which will only happen in the near future.

Vibration at a speed of 100-120 km / h occurs onfor different reasons. These can be quite innocuous problems. But sometimes there are serious cases that require a global intervention in the technical arrangement of the car. Further in the article we will consider the typical reasons for transferring vibration to the steering wheel and body of the car at high speeds.

Wheels

If there are knocks when driving,do not immediately be upset and think about the bad. Practice shows that the reason is most often hidden in tires. Sometimes, in this case, there is not even a need to go to the tire repair shop to make sure of it. Everything will be visible visually.

Balancing out of balance

If there is a vibration of the rudder at speed100-120 km / h, the first thing is to inspect the wheels and tires. They are not perfect. Disks can be uneven or uneven in composition. Since in different places of the tire or disk the weight is different, in the process of rotation the place where the mass is larger will pull the center of gravity. This is nothing but the effect of centrifugal force. Accordingly, at high wheel speeds, this effect will necessarily be transmitted through the rail and traction on the steering wheel. For other damages for the same reason, vibration will also occur on the body.

What is the way out of this situation? The driver needs to balance the wheels. It's better to do this periodically. Also, balancing is mandatory in case of "re-training". What is this process? This is the equalization of the weight of the wheel at each of its points. If violations are detected, the specialist applies special weights to the disc.

Operate the car for a long time atunbalanced wheels can not. This can cause severe wear in some places of the tire, which will increase the vibration. Also because of this, almost all the components and components of the car suspension are excessively worn out. The bearings of the hub are also subjected to heavy loads.

Symptoms of impaired balancing and diagnosis

Determine the disturbed balancing is possible withmovement at high speeds. In this case, the vibration on the steering wheel or on the body will be felt. Diagnose the problem by visual inspection. The wheel disks must be as level as possible, without any dents. If the car recently did not pass at a speed along the pits, and a slight vibration is felt on the steering wheel and on the body, then, most likely, the problem is in the disturbed balancing.

However, do not think that if you hit the wheel, then it's enough to give to balancing only the two front discs. Often, the problem can be rectified only if all four are balanced.

The alignment is disrupted

In direct dependence on the wrongly exposedangle vibration can only be at the moment of acceleration or in a certain range of speeds. Determine the wrong camber / convergence of the wheels can be very quickly - the tires wear out unevenly.

If only the outer one is rubbed or only their inner part is rubbed, then this is the same situation. Correct the problem by adjusting the angles. Then the vibration on the body at a speed of 100-120 km / h will disappear.

But the camber / convergence is adjusted, and the problemdid not go anywhere. The angle is fixed, it's a fact. But the car owner decided not to change tires, because they can still travel. But the rubber "drives" the way it used to. So, it is necessary to change tires or for a certain period of time to drive at low speeds, then the protector will wear out evenly and the problem will be solved.

Vibration on the body and deformed rims

Often the cause of unpleasant fluctuations becomesdeformation of disks. This is easily determined on the balancing stands. Most often, deformations occur due to driving on pits. The problem happens in the spring, when the number of them increases.

If there is no opportunity to stop at the booth, thenYou can try to find a dent visually. Most of all, the disc is jammed from the inside out. Steel stamped discs are more often subjected to deformations than their cast analogues.

In addition to dents, vibration at a speed of 100-120 km / hcan be caused and simply a curved disc. At the same time, the wheel can rotate smoothly on the stand. This is because it is fixed to the central hole on the device. By the same machine, the wheel is not centered during installation. Deformed disks come from the factory.

Chassis

Here, as well as with the wheels, we can distinguisha few reasons. So, when the drive shaft is bent on the wheel, there will be a vibration. This will be reported by constant shaking at the beginning of the movement. Its strength will grow when dispersed. At a speed of 100 km / h the car turns into a rattle. And if you accelerate even more, the car leaves the rectilinear trajectory.

Often, vibration at a speed of 100-120 occurs after the replacement of the brake discs. Shaking will inform the car owner of a loose disc. At the speed of the disk, the backlash, which is given to the body and the steering wheel.

CV joints are another reason. Check this item can be very simple. It is enough to take the shaft articulated and try to crank it. If there are any loopholes, even small ones, the CV joints must be replaced. An additional feature is a torn asshole.

And, of course, it is worth checking the wheel bearings. If they are damaged, the body will necessarily vibrate. The shaking is felt at any speed.

Worn Suspension

Strongly worn chassis parts canprovoke vibration in the steering wheel. The suspension affects the contact of the car with the road. If there is a backlash in the running gear, then this is the cause of the imbalance during rotation. But the backlash of the suspension is just a "catalyst" of shaking on the wheel. It by itself can not serve as the main reason for the fact that the rudder vibration appeared.

Speeds of 100-120 (VAZ-2108 - not an exception) can youdemonstrate it when the car has a malfunction of the steering gear. It is necessary to eliminate these breakdowns in the first place. It may be dangerous. However, diagnosing problems is necessary in the last place, if all other nodes are in perfect order.

Other reasons

All causes of vibration at a speed of 100-120 km / hcan provoke shaking and at another speed. But if the body shakes only on high, then the main suspect is the motor, or rather, its incorrect installation. This is often preceded by engine repairs. To get rid of the consequences, remove the suspension, loosen the engine mounts, and then reinstall it.

The wheel fastening is loose

This problem can easily be identified and eliminated, sincebecause of this, vibration occurs at a speed of 100-120. VAZ-2110 will produce a characteristic deaf sound. The case is in the weakened nuts and bolts fixing one wheel or several. Do not neglect the test, it can be dangerous. The wheel can simply unscrew while driving.

The very beating is very similar to the vibration on the steering wheel andbody when the reason was in wheels and tires. The difference here is that this shaking starts at low speeds. Observe this phenomenon can be at different speeds.

So, we have found out, for what reasons there is a vibration on the body when driving at a speed of more than 100 kilometers per hour.
