The car body vibrates: causes and consequences. Car vibration, causes, remedies Shakes the car when driving on a flat road

There can be a huge number of options for malfunctions in a car, and not always a specific breakdown gives specific signs of its presence. Drivers often complain about body shaking during acceleration or at a certain speed. There can be quite a few problems that determine this indicator. If your car has vibration during acceleration, you should look at all possible breakdowns and immediately replace the failed nodes.

By the nature of the vibration, it is not always possible to tell exactly where the problem lies. On different cars, only the steering column can vibrate, giving the driver into the hands, or the entire body can shake. It all depends on the design, nature and degree of damage to the components and assemblies that are worth changing. Let's look at the main causes of vibration during acceleration.

We study the wheels and chassis - the main cause of vibrations

The main indicator that the wheels or the drives of these same wheels are to blame for your problems is shaking at a certain speed. Often these are body vibrations in the range of 80-100 kilometers per hour, but sometimes the shaking may not go away even after 60 km / h, so in any case, you need to fully diagnose the chassis.

At the same time, it is not necessary to go to the service station and carry out expensive diagnostic operations. It is enough to apply all your knowledge and study each chassis unit for a possible breakdown. The most common problems in this case are the following points:

• the wheel mounts are unscrewed, which causes vibration on one of the wheels;
• the brake disc is poorly fixed, at speed it begins to vibrate;
• the wheel drive shaft is bent - the body vibrates constantly, with an increase in speed, the vibration intensifies;
• CV joints are damaged - this is the most common problem that causes vibrations on the body;
• wheel bearings are damaged, which causes shaking at any speed.

The most common malfunction in this manifestation is CV joints. To check their serviceability, it is enough to take the shaft with your hand and try to turn it. If the shaft has play more than a couple of millimeters, the CV joint must be replaced. Interestingly, the vibrations of the car body during acceleration can cause both external and internal CV joints.

You can also easily determine the malfunction of this chassis mechanism by examining the anthers. If the rubber part of the anther breaks, we can safely talk about the malfunctions of this mechanism. If water, dust and dirt get into the CV joint, the assembly does not survive for more than a few days.

Wheel alignment and rubber quality is another reason for shaking

If the angle of the wheels is incorrect, vibration, the machine can be pulled to the side, uneven rubber eating, and other unpleasant manifestations. In different models, these problems manifest themselves in different aspects. Adjusting the toe-in angles is one of the first processes to be performed after detecting such a nuisance as body vibration.

Also, tires that are worn incorrectly, or a disc after a serious blow, can cause problems. The main processes that can be taken to eliminate body vibration in this case are as follows:

• adjustment of the angle of the wheels at the station with the wheel alignment service;
• replacement of rubber with visual indicators of uneven or excessive wear;
• replacement or repair of a disk on which dents and uneven rims are visible;
• wheel balancing - often during operation, balancing weights fly off.

If the balance weights have come off the wheel, it may well cause vibrations at speeds of 80 kilometers per hour or more. The problem is that it is simply impossible to determine this on your own and find out which wheel needs to be sent for balancing. Therefore, you will have to go to a tire fitting and balance all the wheels of your car.

This is one of the most inexpensive and safe options for breakdowns due to vibration of the body or steering wheel during acceleration. Therefore, the first step is to check for the presence of such malfunctions, and then translate suspicions into other options.

Engine mounts, tie rods and other problems

There is another group of problems that cause vibrations when accelerating a car. These problems are difficult to collect in one bunch, because they are all different and arise for various reasons. Often vibration occurs when one of the engine mounts is broken. This can be easily checked by increasing the speed while shaking.

Also, the gearbox can be the culprit for such a manifestation of problems. If the car starts to shake at 80 kilometers per hour, you can very easily check the fault of the checkpoint by doing the following procedures:

• accelerate to a speed of about 85 kilometers per hour;
• depress the clutch and watch the vibration change;
• engage third gear and slowly release the clutch;
• try acceleration from 50-55 kilometers per hour in last gear.

If the nature of the shaking does not change in all these experiments, the box has nothing to do with this problem. If there is more shaking when the gearbox is connected, you will have to check its involvement in this problem.

You can also check the automatic box. It is enough to switch the gearbox selector to modes 3, 2, D, N at a speed of about 85-90 kilometers per hour and observe the operation of the box itself and the change in vibrations. Often the box is not to blame for the vibration of the car body, but there are such cases.

Summing up

If you have not been able to find a problem that caused vibrations in the body or steering wheel in your car during acceleration, you should contact the experts. Do not leave this problem, because it can worsen and create dangerous driving conditions for the driver and passengers of the car. It is necessary to respond as quickly as possible to all possible problems and eliminate them by replacing the failed elements of the machine.

Often, to determine the problem, you don’t even have to go to the service station and use expensive diagnostics. It is enough to inspect the car yourself and determine which problems caused the vibrations of the body. Have you had similar problems in your experience, and what parts of the machine caused them?

Vibration of the body at speed means that there are problems with some of the units of your car. Vibration is often caused by steering malfunctions, destruction of engine or gearbox mounts, and other malfunctions.
Vibration in the body when braking may be due to wear of the pads or imbalance (wear) of the brake drums (or discs).

Damage from vibration

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

At speed, the vibration of the car body is not only discomfort for the driver and passengers, it is also harmful to the car as a whole. After some time, cracks appear in the body of the car from vibration. In addition, bolts and nuts begin to loosen spontaneously, which leads to dangerous consequences in the future. Thus, there is a risk of emergency situations. In addition, vibrations are harmful to human health, cause vasoconstriction, impair blood circulation, and lead to the deposition of salts in the joints, reducing mobility during prolonged exposure.

Causes

Vibration in the body during acceleration occurs due to an imbalance in the chassis of the car, there are several reasons at once:

• constructive reason, due to the design of the part that violates the balance, for example, the tire inflation valve affects the wheel balance (may violate it);
• Technological reason, here the vibration is caused by a deviation from the dimensions and parameters of those elements that are being replaced;

For example, the mass of the repair connecting rod may deviate from the normal value, due to which an uneven load distribution occurs in the motor and, as a result, vibrations during acceleration, in motion, and even vibration along the body at idle.

• Operational reason, vibration occurs when the part is unevenly worn, deformed, or may be due to loss of properties (destruction) of vibration isolators.

Vibration isolators are motor mounting cushions, boxes and others. They reduce the shocks that are transmitted from the engine to the frame and body of the car. These supports (pillows) are usually made of a pair of metal elements that are separated by a rubber layer. Vibration of the body during acceleration and at idle can occur due to their destruction. Occurs when the rubber material is worn out or the manufacturing technology is violated. If the vibration of the body during acceleration is due to pillows, they should be replaced immediately

If the engine vibrates constantly, then the most effective way is to balance the parts. Of course, it will be difficult to 100% eliminate vibrations that occur from the engine, but it is realistic to significantly reduce the level of vibrations to a minimum.

When performing the balancing procedure, the part is subjected to diagnostics. With the help of a special device, its heaviest side is determined. Then the master decides whether to lighten the heavy part or make the opposite side heavier. This option is used when balancing wheel disks. It is important to note that it is almost impossible to independently determine the light and heavy side of the wheel, and the crankshaft - all the more, without equipment and experience.

Balancing Methods

There are a couple of ways to balance a particular part:

• Static way;
• dynamic way.

Each of these methods has its own characteristics.

Static balancing– performed without forced rotation of the part. This method does not require expensive equipment, it can be used in a garage. However, it should be remembered that the imbalance is not completely removed in a static way. The essence of the method is that the part to be balanced is mounted on prisms or bearings. Then the element rotates around its own axis, at the end of the rotation it takes a position in which its heavier side will be located below the axis of rotation. It is important to note that the prism must be strictly horizontal, and the bearings must rotate with minimal resistance. Then the heavy side will outweigh the light side, and the part will deviate from the center because of this.

Dynamic balancing- this method requires the use of constant rotation of the part using special equipment. This method allows you to completely get rid of the imbalance, while the method can be applied to the most rigid parts of any size (such as a crankshaft, cardan, flywheel, and others).
All data on deviations with high accuracy is issued by a computer. By dynamically balancing parts of the crankshaft, wheel hub, clutch basket and brake drums (or discs), the heavier side is lightened by removing material from it. It all depends on the type of product, whether drilling or other machining is performed.

How to find the reason

How to find the source of vibration without specialized tools? Without special equipment at hand, it is impossible to determine the excess of the vibration level of the hull. In addition, each owner of the car perceives this subjectively - for one driver, vibrations and knocks during acceleration of the car are a common thing. For another driver, even a rustle can be cause for panic.

However, shaking is considered unacceptable in the following cases:

• When objects lying on the dashboard begin to move on their own;
• When a strong (giving in the palm of your hand) vibration of the steering wheel is felt;
• When the steering wheel vibrates and the body vibrates, the cause of the problem is often the imbalance of the front wheels;
• When the reflection in the interior mirror starts to blur;
• If vibration of the floor or controls is felt, especially at low engine speeds;

First, you should remember that shaking can occur due to uneven operation of the motor. Perhaps, most recently, you contacted a service station for the purpose of repairing a motor (for example, replacing a crankshaft). In this case, it is likely that the new crankshaft did not go through the balancing procedure along with the flywheel. In addition, increased oscillations on the body arise from improper adjustment of the carburetor, or throttle. In this case, the mixture does not completely burn out, and the engine idling turns below 800 rpm.

The first step is to inspect the condition of the engine mounts, box, intake and exhaust systems and parts that are located near them. Perform diagnostics first with the engine off, then with the engine running. Engine mounts (pillows) must always be solid. If a crack appears, or the pillow shrinks, the pillow is replaced. Vibration in the body after replacing the pillow with your own hands should disappear. Engine protection can sometimes be very close to the sump - when there is a small gap between the protection and the sump, most likely vibration and knocks occur due to their contact.

Then you need to check the quality of the tightening of the threaded connections, the fastening of the motor and other units. If you find a loose bolt, you will need to tighten it to the required level. There are times when vibrations appear due to the impeller of the fan that cools the radiator. In this case, remove the impeller and listen to the operation of the motor without it. Then you need to turn off the attachments one by one (removing the drive belts), and check the level of engine shaking after starting and when it is operating in different modes.

It may be necessary to balance the pulley or replace the belt. Sometimes the clutch basket with the flywheel becomes the cause of concussions. To calculate them, you need to press the clutch pedal to the floor, start the engine “in gear”, and after a couple of seconds turn on the “neutral”, then remove your foot from the pedal. If the shaking continues, then it is due to the flywheel or basket. An imbalance of the cylinder-piston group is possible, especially if one or two pistons or one or two connecting rods have changed from all.

The instruction says if the vibration of the body after 80 kilometers per hour, most often it occurs due to transmission elements or the chassis of the machine.

When the vibration of the motor changes with the speed of the car, most likely one of the nodes following the gearbox output shaft vibrates. These are cardan or drive shafts, parts of the transfer case (if it is installed in your car), wheels or hubs. By the way, when body vibration occurs during braking, the price of the issue is your life! The problem lies in the brake discs or drums. Your safety depends on the proper operation of the brakes, so you can’t delay repairs. Such vibrations on the steering wheel are especially noticeable.

Another reason for shaking can be poor-quality rubber tires. Its composition can be very rigid, because of this, the load on the front wheels increases when the speed of the car drops. Vibration of the car at a speed of only 10-15 kilometers per hour indicates an imbalance in the wheels. As a rule, a similar problem occurs after changing the car's shoes to winter tires. Eliminated by wheel balancing. If the wheels are front, it can manifest itself in the form of a beating steering wheel.

To check if the wheels are to blame for the vibration during acceleration, you need to swap the front and rear places. However, it is best to diagnose the car, then its elements will be checked at the stand and the cause will be reliably identified. Disc imbalance is solved by hanging weights. The mass of weights can reach from 5 grams to 100 grams. After proper balancing weights, during acceleration, the vibration will disappear. Best of all, balancing will be done at a tire fitting shop, the owner himself will not be able to cope with this.

Vibration after a major overhaul is caused by an imbalance in the cylinder-piston group, its incorrect assembly or deformation of parts. Pistons and connecting rods are always selected by weight. The difference in weight should not be more than 5-10 grams.

Attention: The pistons must also be of the same diameter, otherwise there will be a difference in the compression of the cylinders, hence vibrations and damage to parts.

Another common cause of oscillation is the cardan shaft:

To fix this problem, you need to remove the shaft. Then follow the steps in the following order:

• It is necessary to check the condition of the crosses at the ends of this shaft;
• Check that each crosspiece moves freely in any direction when pressed without effort;
• If it is necessary to make efforts, or in some direction the crosspiece does not move at all, then it must be replaced;
• If it is necessary to replace the crosses, at the same time you need to check the presence of grease in the caps for roller bearings;
• Having completed the check of the crosses, you can proceed to check the spline connection of the cardan;
• To do this, you need to simultaneously twist the parts of the cardan around the axis;
• In this case, the free play should not exceed 1 millimeter;
• When the spline part is damaged, then the cardan must be replaced;

Another reason for the occurrence of vibrations in the body at idle is the incorrect fastening of the transfer case, you need to adjust it. If you don't have one, you can skip this paragraph. You need to raise the car with a jack or a lift. Wheels during work should not come into contact with the ground. In addition, it is necessary to provide free access to any fasteners of the handout.

Start by inspecting the condition of the fasteners. They usually do not have good strength, as they are made of aluminum alloy. On inspection, pay attention to cracks and chips on them. If there is a need to replace the old mount with a new one, then a gasket must be laid between the mount and the body, which is best made from a conveyor belt. When removing the transfer case, special attention should be paid to the intermediate shaft located between the gearbox and transfer case. After performing the checks described by us, the dispenser should be returned to its place. First, it is hung on the fasteners, while the nuts are not fully tightened. Then you need to ask an assistant to accelerate the car to 80 km / h. Only then can the nuts be tightened to the end.

That's all, now you are able to determine the cause of the shaking and eliminate it.

Probably, not every driver noticed such a phenomenon, but still a lot of motorists were faced with the fact that the car was shaking while driving. The most common causes of this defect are:

• Poor wheel balancing (you can find out what wheel balancing is by following the link);
• Problem with brake discs;
• Play of one of the driving wheels;
• Other reasons that are almost impossible to determine on their own;

We have already discussed what balancing is, but we repeat that when there is an imbalance on the wheels or on one of the wheels, this will certainly affect the smoothness of movement. In this case, the car will definitely start to shake, and the faster the car moves, the more noticeable the shaking will be. If the imbalance is on the front wheels, then the steering wheel may begin to shake at speed, and if on the rear wheels, then the shaking will be transmitted to the car body.

To test this version, you need to thoroughly wash the rims inside and out. It may be that 20-30 grams of dirt give a very noticeable imbalance. If after these steps the problem has not disappeared, then you should go to a tire service and ask to check the balance. If even after balancing the problem does not go away, then you should think about other reasons.

Why can shake the steering wheel at speed

If we have discarded the first possible reason, then we will move on to the second. It is important to understand that if the steering wheel shakes at speed, then the problem is somewhere in the front of the car. Perhaps you recently had a long trip, or you braked for a long time and then got into a puddle. I bring to the fact that perhaps your brake discs have been driven, and they have ceased to be the form in which they were originally. That is, an imbalance also appears here, but not as a wheel, but as a bundle of the hub, disk and wheel as one whole. The reason is unlikely, but there is a place to be and this must also be checked and excluded.

Also, according to the statistics of service centers, one of the probable causes may be the play of one of the wheels parallel to the ground. If there is such a possibility, then raise the car on a lift and check this version and also exclude it.
Among all the possible reasons, there can be anything, so to make sure of this for sure, you will need to use the services of specialists, because this is your safety.

Many motorists are familiar with the problem when vibration occurs when accelerating. The reasons for this phenomenon are many. Often, the search for a source can even drive a car enthusiast crazy. Let's look at the main causes of shaking, because you really want the car to drive quietly and smoothly. In 75% of cases, the problem is detected and eliminated, and the car owner can again feel calm and comfortable.

Vibrations: don't get depressed

If the car shakes, and where the source is unclear, do not panic. If the car is from 3 to 5 years old, then most likely, any components have worked out the resource allotted by the manufacturer and have worn out. So iron "horses" show their age. When shaking is detected, it is not worth taking the car to the service station for diagnostics - you can find the cause yourself.

Shaking steering wheel when accelerating

Quite often, when driving, a strong vibration occurs on the steering wheel when accelerating. At first, it is barely noticeable, but over time it becomes more and more noticeable. This can cause serious damage and lead to an accident.

The first step is to check the wheel balance. To do this, you can go to the nearest tire shop. If your wheels are out of balance, then this is one of the most popular causes of shaking when accelerating. Fixing the problem won't be expensive. Sometimes the disc becomes clogged with mud or snow, then these beatings can occur and stop. Determining the presence of dirt in the case of alloy wheels is very simple, and in steel, where the ventilation holes are small, it is difficult. Dirt collects inside the part.

The need for balancing

Neither tires nor wheels are perfect in terms of geometry and composition.
So, due to the different masses in different parts of the wheel, those places where the weight is greater will pull on the wheel axle. At high speeds, the force will be transmitted to the traction, then to the steering wheel.

It is very important to balance from time to time. Especially after changing tires or wheels. With this procedure, it is possible to align the masses of the wheels at each point. Driving a vehicle with unbalanced wheels can cause rapid wear on the chassis and suspension, which is more difficult to fix.

If the balance is off

The main symptoms are slight shaking of the entire car when accelerating. If you haven't changed the wheels, if the rims are perfectly flat and the driving style is neat, but at the same time there is a strange vibration when accelerating, then this is the problem.

You should not think that if the beats are felt on the steering wheel, then only the front wheels need to be balanced. It is better to do this operation on all four.

Warped disc or damaged tire

Often, after diagnostic procedures, it is possible to find out another cause of beating - crooked wheels. This can be determined by any tire fitting specialist at a special stand. If it jumps when testing a wheel on a test bench, then it's time to start worrying. It is important to see if the disc jumps with the tire. Jumping? Blame the disk, no? So the tire needs to be replaced.

pressure inside

Less commonly, vibration during acceleration occurs due to insufficient pressure.
This is very easy to diagnose and fix.

Unreliable wheel mounts

This problem is also easy to fix and diagnose. This is a simple but very dangerous reason. Fastenings can be loose even on one wheel, and this is enough to cause shaking. If the problem is not fixed in time, emergency situations are possible. If the wheel comes off while driving, the repair will be quite expensive - you will have to replace the disc and hub,

The symptoms in this case are very similar to vibrations due to tires or bent rims. But there is a cyclicity here, though not at all speeds.

wheel alignment

If the wheel is installed at the wrong angle, this is also one of the causes of unpleasant beats. Adjusting these angles is an important process once body vibrations are detected. What can be done to fix it? Adjust wheel alignment on a special stand. It is also recommended to replace the rubber if it is seen that it is wearing out incorrectly.

Check suspension and chassis

Vibration during acceleration can occur as a result of natural wear of the struts or shock absorbers. The suspension stops working smoothly, which is one of the causes of the problem. This is especially noticeable on rough roads or when driving at speed.

Another popular cause of shaking is the support bearing on the strut. This part can be found on top, above the shock absorber. It is also checked from the front under the hood. If it was possible to find a worn bearing, it should be replaced, and then the problem will be solved.

Ball joints wear out in most cases due to driving on poor quality roads. In the conditions of our country, these details need to be changed very often. If you find a backlash in the supports, then perhaps a replacement will be able to regain comfort.

Check and, if necessary, replace the tie rod ends. Over time, play appears in this mechanism due to wear. Thanks to this tip, the wheels of the car can turn in parallel. Tip wear causes shaking.

Vibration when accelerating

This is terrible, especially when you need to accelerate quickly, for example, if you need to overtake another car. Often when you press the pedal, acceleration is jerky and uneven. A few simple steps are required to make a correct diagnosis.

Check the oil level in the gearbox. Unexpectedly, low gear oil levels cause vibration and shaking during acceleration. Also, the car can noticeably lose in dynamic characteristics. Jerks when pressing the accelerator pedal - this can also be due to a lack of oil.

It comes from anything. There are a lot of reasons. But if you try, you can detect them yourself and not pay for diagnostic services in the service station. But if suddenly you cannot figure it out on your own, do not put off the decision indefinitely. This leads to bad consequences. With the help of simple steps, you will definitely find the causes of vibrations on your car and eliminate them. Treat malfunctions with all seriousness, because a neglected problem can cause an accident.

The sources of vibrations during movement can be different, but in any case, they indicate malfunctions in certain parts of the car. By their nature, it is often possible to identify a malfunction. How to make such a diagnosis and what to look for in case of vibrations, we want to tell in this article.

1 What are vibrations and when to sound the alarm?

Vibrations occur in the car as a result of the action of centrifugal forces. Moreover, they are present in any car, even a new one, and this is normal. Accordingly, the car owner needs to feel the threshold when the vibration, when driving, goes from acceptable to "unhealthy", i.e. indicating any malfunction. There is no device that measures the level of vibrations. Therefore, you need to rely only on your own feelings.

Of course, it is not easy for novice motorists to cope with this task, so you should pay attention to the following symptoms:

• objects lying on the torpedo, even when moving on a flat road, move and fall;
• even with a light touch on the steering wheel, vibration is clearly felt;
• in the rearview mirror it is impossible to catch the focus.

Please note that vibrations have the most negative effect on the condition of the entire car. Therefore, it is necessary to identify them as early as possible, find the cause and eliminate it.

2 Isn't it time to fix the weight on the disks - from simple to complex

The most common cause of vibration is wheel imbalance. Therefore, troubleshooting begins with it. And it absolutely does not matter when the last time you performed wheel balancing was a month or a week ago. Even if you left the service station and "caught" the hole unsuccessfully, the setting may be broken. Also, unbalancing often occurs as a result of unscrupulous service station workers who fix the weights poorly or perform the settings incorrectly, for example, do not wash the wheel before fixing it on the stand.

Vibration associated with wheel imbalance, as a rule, appears at low speeds - 30-40 km / h, sometimes - 60-70 km / h. With a set speed of up to 80-100 km / h, it turns into a real shaking, at which it is impossible to continue moving. There is only one way out in such a situation - to call in the nearest tire shop and fix the problem, escaping with a slight fright and several hundred rubles.

Sometimes vibrations occur due to uneven tire pressure. Therefore, be sure to check it and, if necessary, correct it.

3 Vibrations of the internal combustion engine - the power unit is peddling

If vibrations appear only during acceleration, problems must be sought in the operation of the engine. As a rule, they are accompanied by a loss of power, twitching that occurs only at certain speeds and a decrease in vehicle dynamics. In this case, first of all, it is necessary to check the fuel system. Start looking for the cause from a simple one - replacing the fuel filter.

I must say that the fuel filter can become unusable not only because of the high mileage, but also after pouring low-quality fuel. If the fuel pump is clogged, then the carburetor / injector will probably also need to be flushed. Note that flushing the carburetor may be required even after a long period of inactivity of the car, for example, if you do not use the car in the winter.

If there are no malfunctions in the fuel system, attention must be paid to the electrician. Unfortunately, they manifest themselves in almost the same way as fuel system malfunctions, so it will not work to determine by the symptoms why the car is vibrating. Most often, the following elements of the ignition system fail:

• candles;
• candlesticks - even a small, barely noticeable crack in the cap is enough for the candle to work intermittently and cause the engine to "tune";
• high voltage wires.

I must say that in some cases you can even hear a characteristic crackle under the hood, indicating a breakdown of the high-voltage wire. To find out exactly where the spark jumps, we start the engine in the dark and open the hood. Most often, a spark can be seen visually. If the wires and candles are normal, we check electronic sensors on modern cars. It will not work on your own, so you should contact qualified specialists with special equipment.

4 Transmission problems - how to diagnose?

Often the causes of vibration are related to the transmission. Determining them is quite simple: if the box is mechanical, we simply squeeze the clutch while driving. On the automatic transmission, you need to switch the lever to the "N" position. If the vibrations are gone, then this indicates problems in the gearbox. True, on rear-wheel drive vehicles, in addition to the box, the cardan, or rather, its crosses, as well as the rear axle gearbox, can serve as a source of vibration. The latter, in the event of a malfunction, makes a loud noise during movement.

There are situations when vibrations appear only after pressing the clutch pedal or shifting the lever to the "N" position on the automatic transmission. In this case, the following components of the car can be blamed:

• torque converter;
• clutch basket;
• flywheel;
• crankshaft;
• unbalanced connecting rods and pistons.

To prolong the life of the box, do not forget that it also requires an oil change, even if the manufacturer himself reports that the oil is filled for life and does not need to be replaced. The fact is that by the standards of automakers, the life of a car is only 5 years.

You are unlikely to learn more accurately to identify the cause of transmission malfunctions. Actually, this is useless, since in any case, to eliminate them, you must contact the service center.

That's all the most common causes of vibrations in the car while driving. True, another source of them is the suspension or steering system. However, identifying such problems is usually not difficult even for beginners, since vibrations are accompanied by characteristic knocking sounds and manifest themselves when driving on rough roads or when entering turns at high speed.
