Strong vibration when dialing speed: causes

Many car enthusiasts are familiar with the problem when when speed dialing a vibration occurs. There are a lot of reasons for this phenomenon. Often the search for a source can even drive a motorist crazy. Let's consider the main reasons for the appearance of shaking, because you want the car to go quietly and smoothly. In 75% of cases, the problem is detected and eliminated, and the car owner can again feel calm and comfortable.

Vibration: do not fall into depression

If the car shakes, and where the source is, it's unclear, do not panic. If the car is from 3 to 5 years, then most likely, any components worked off the manufacturer's assigned resource and worn out. So the iron "horses" show their age. It is not necessary to detect the shaking of cars in the SRT for diagnosis - the cause can be found independently.

Shakes the wheel when dialing speed

Quite often when driving on the steering wheel there is a strong vibration when dialing speed. At first, it is barely noticeable, but in time it becomes more tangible. This can cause serious breakdowns and lead to an accident.

The first thing to check is the balancing of the wheels. To do this, you can go to the nearest tire service. If your wheels are unbalanced, then this is one of the popular reasons for shaking when dialing speed. Eliminating the problem will not be expensive. Sometimes a disc is clogged with dirt or snow, then these beats can arise and stop. Determine the presence of dirt in the case of cast discs is very simple, and in steel, where the ventilation holes are small, it is difficult. Dirt is collected inside the part.

Necessity of balancing

Neither tires nor wheels are not perfect in terms of geometry and composition.
So, because of the different masses in different parts of the wheel, those places where the weight is bigger will pull on the wheel axle. At high speeds, the force will be transferred to the traction, then to the steering wheel.

It is very important to carry out balancing from time to time. Especially after changing tires or disks. With this procedure, you can align the masses of the wheels at each point. Using a car with unbalanced wheels can lead to rapid wear of the chassis and suspension, and this problem is more difficult to fix.

If the balancing is broken

The main symptoms are a slight shaking of the entire car when speed is set. If you do not change the wheels, if the wheels are perfectly flat, and the driving style is neat, but with all the same, strange vibration occurs at speed dialing, the problem is precisely this.

Do 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.

Deformed disc or damaged tire

Often after diagnostic procedures it is possible to find out one more reason for the beats - the curved wheels. It can be determined by any specialist in tire fitting on a special stand. If, when testing the wheel on the test bench, it jumps, then it's time to start worrying. It is important to see if the disk is jumping along with the tire. Jumping? Blame the disc, no? So, the tire is under replacement.

Pressure inside

Less often, vibration during speed dialing is due to insufficient pressure.
This is very easy to diagnose and eliminate.

Unreliable fastening of wheels

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

Symptomatics in this case is very similar to vibration due to tires or bent discs. But here there is a cyclicity, however, not at all speeds.

Collision alignment

If the wheel is installed at the wrong angle, this is also one of the reasons for the appearance of unpleasant beats. Adjusting these corners is an important process after detecting body vibrations. What can be done to eliminate it? Adjust the camber on the special stand. Also it is recommended to replace the rubber, if it is clear that it is worn out incorrectly.

Check the suspension and chassis

Vibration in speed dialing can occur as a result of natural wear of the racks or shock absorbers. Suspension stops working smoothly, which is one of the reasons for the problem. Especially it can be seen on uneven roads or when driving at speed.

Another popular reason for shaking is the support bearing on the rack. This part can be found from above, above the shock absorber. Also in front it is checked under the hood. If it is possible to detect the worn bearing, it should be replaced, and then the problem will be solved.

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

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

Vibration when dialing speed

It's terrible, especially if you need a quick overclock, for example, if you need to overtake another car. Often when you press the pedal, acceleration is performed by jerks and unevenly. To make the right diagnosis, you need to perform a few simple steps.

Check the oil level in the gearbox. Unexpectedly, but the low level of the transmission oil causes vibration and shaking during acceleration. Also the machine can noticeably lose its dynamic characteristics. Jerks when you press the accelerator pedal - this can also be a consequence of a lack of oil.

The dirty filter of the automatic transmission leads to various unpleasant effects. You can perform replacement yourself, or you can use the services of specialists.

A worn cardan shaft is guaranteed tangible vibration of the car when speed dialing. Here the vulnerable place is the cross. If necessary, replace the part, otherwise it can lead to more serious damage.

Also, such unpleasantness can be caused by uneven engine operation. This often happens after repairs. Sometimes professionals from the SRT simply forget to perform the balancing of the crankshaft and the flywheel. Another reason is a misconfigured carburettor.

Engine pillows, gearbox and other reasons

This is another possible group of reasons, because of which the machine can shake during overclocking. All these problems can arise on different occasions. For example, as a result of inspections, a breakdown of one of the cushions of the power unit is detected. It's easy to find out - increase the engine speed at the time of vibration.

Still body vibration at acceleration of 80 km / h and up to 100 km / h can appear at malfunctions with a check point. Check this hypothesis is very simple. Recommend a speed of about 85 km / h, then squeeze the clutch pedal and watch how the car behaves. Turn on the third gear and release the clutch. Accelerate from 50 km in the last gear box.

If the nature of the beats does not change during all these activities, the checkpoint is not to blame. If the level of vibration increases, when the box is connected to the work, then you can check its involvement.

This method is suitable for both mechanical boxes and automatic transmissions. In the case of an automatic machine at speeds of approximately 90 km / h, turn on the box 3.2, D, N, and then monitor the operation of the automatic transmission and the car. Watch for vibrations. Most often the fault of the box in the beats is minimal, but practice shows that such a probability exists.

What else to pay attention to?

Vibration at speed dialing can be felt due to unreliable engine attachment and exhaust system parts. It is better to carry out this check on the engine, which is started and then muffled. Also, there are times when a damaged radiator fan causes a shaking.

Then check the attachments. Often, the problem can be solved by replacing the drive belts or by balancing the pulley. It is not superfluous to check the clutch basket and flywheel. You can do this as follows. Squeeze out the clutch and install the selector for the first gear. Then start the engine and wait a couple of seconds. Then the lever is moved to the neutral position, and the foot is removed from the pedal. Vibration is still there? Look for the problem in the flywheel and clutch basket.

SHRUSS in front axles

This though not so popular reason, but quite a vulnerable place, because of what the vibration when typing speed - a common phenomenon. Experienced motorists recommend starting the diagnosis with this mechanism. The procedure must necessarily include a tactile check. In the presence of scratches - hinges of equal angular under replacement. It is better to replace this part with a pair.

Let's sum up the results

So, among the common reasons can be identified wheel mounts, poorly fixed brake discs, deformed drive shaft, joints of equal angular speeds, bearings of the hub.

There is a vibration when dispersing from anything. There are a lot of reasons. But if you try, you can find them yourself and do not pay for diagnostic services in the SRT. But if suddenly you can not figure it out on your own, do not postpone the decision in the long box. This leads to bad consequences. With simple actions, you will certainly find the causes of vibrations on your car and eliminate them. Take the trouble seriously, because a running problem can cause an accident.
