Strong vibration at a set rate: causes

Many motorists are familiar with the problem, when the set speed there is a vibration. The reasons for this phenomenon – mass. Often the source can even drive a motorist crazy. Let's consider the main causes of shaking, we want the car rode silently and smoothly. In 75% of cases the problem is detected and eliminated, and the owner can once again feel relaxed and comfortable.

Vibration: don't feel depressed

If the car shakes, and where the source is unclear, do not panic. If the car from 3 to 5 years, it is likely that any components of worked allocated by the manufacturer of the resource and worn out. So iron "horses" show your age. Not worth it when shaking is detected to carry a car in a HUNDRED on the diagnosis – the reason you can find yourself.

The steering wheel Shakes at high speed

Quite often when driving the steering wheel there is a strong vibration at a set rate. At first, she barely noticeable, but over time it becomes more tangible. It can be cause serious damage and lead to accident.

The First thing you need to check the wheel balancing. For this you can go to the nearest tire. If your wheel is unbalanced, it is one of the popular reasons of shaking at a set rate. Fixing the problem won't be expensive. Sometimes the disc is clogged with dirt or snow, then these beats may arise and will cease. To determine the presence of dirt in the case of alloy wheels is very simple and the steel where the holes for ventilation of small hard. Dirt gather inside details.

The Need for balancing

No tires, no rims are not perfect in terms of geometry and composition.
So, because of the different masses in different parts of the wheel, the places where the most weight will pull the wheel axle. At high speeds the force will be transmitted to the traction to the wheel.

It is Very important from time to time to carry out the balancing. Especially after changing tyres or discs. Using such procedure it is possible to align the mass of the wheel at each point. The use of the car with neutralisieren wheels can cause rapid wear of the undercarriage and suspension, as this issue fix is more difficult.

If the balancing is broken

The Main symptoms – a gentle shaking of the entire vehicle at a set speed. If you have not changed the wheel, if the disks are perfectly flat, and the driving style is neat, but there was a strange vibration at high speed, the problem is.

We should Not think that if the heartbeat is felt on the steering wheel, it is necessary to balance only the front wheels. Better to do this operation on all four.

Deformed disc or a damaged tire

Often after diagnostic procedures can determine the cause of the beating curves of the wheel. It can define any person by mounting on a special stand. If you test the wheel on a test stand it jumps, then it's time to start worrying. It is important to see jumps if the disk together with the tire. Jumps? Blame the disk, no? So, the tire replacement.

Pressure within

Less vibration at high speed due to an insufficient pressure level.
It is very easily diagnosed and eliminated.

Unreliable attachment of the wheels

Such a problem too easy to fix and diagnose. This is a simple, but very dangerous cause. The mounts can be weakened even on one wheel, and that was enough to cause shaking. If the problem is not solved in time, possible emergency situation. If the wheel will bounce when driving, the repair will be quite expensive – you will have to replace the disc and hub, brake disc.

The Symptoms in this case are very similar to vibration due to tires or bent discs. But there is a recurrence, though not on all speeds.

Alignments

If the wheel is set at the wrong angle, it is also one of the causes of bad beats. Adjustment of these angles – an important process after the detection of the vibrations of the body. What can I do to resolve? To adjust the alignment on a special stand. Also recommend replacing the rubber if it's obvious that she wears is wrong.

Check the suspension and chassis

Vibration at high speed may occur as a result of natural wear struts or shock absorbers. The suspension is no longer running smoothly, which is one of the reasons for the problem. Especially it can be noticed on rough roads or when driving at speed.

Another popular cause of shaking – bearing at the front. This detail can be found at the top, above the absorber. Also the front of her checking under the hood. If you managed to find a worn bearing should be replaced and then the problem will be solved.

Ball joints, in most cases wear out because of the traffic on the roads of low quality. In our country, these items need to be changed very often. If you find the play in the bearings, then maybe the replacement will be able to regaincomfort.

Check and if necessary replace tips of steering draught. Over time, this mechanism appears backlash due to wear. Thanks to this tip wheels of the car can rotate in parallel. The wear of the tips is causing the vibration.

Vibrate when typing speed

It's awful, especially when you need rapid acceleration, for example, if you need to overtake another vehicle. Often when you press on the pedal the acceleration runs choppy and uneven. For correct diagnosis it is required to follow a few simple steps.

Check the oil level in the transaxle. Unexpectedly, but low transmission fluid level causes vibrations during acceleration. Also the machine can significantly lose in dynamic characteristics. Jerks when pressing on the accelerator pedal – it can also be due to lack of oil.

A Dirty filter automatic transmission leads to various unpleasant effects. You can replace with your own hands or to use the services of specialists.

A Worn driveshaft – this is a guaranteed tangible vibration of the vehicle at a set speed. Here vulnerability – cross. If necessary, replace the item, otherwise it may lead to more serious damage.

Also, this problem can be caused by uneven engine operation. This often happens after the repairs. Sometimes professionals from a HUNDRED simply forget to perform balancing of the crankshaft and flywheel. Another reason – an incorrectly tuned carb.

Pillow engine, transmission and other causes

This is another possible group of causes due to which a car may shake upon acceleration. All these problems can occur for various reasons. For example, the surveys detected the failure of one of the pillows of the power unit. It's just to find out – increase the engine speed at the time of occurrence of vibration.

Even the vibration of the body during acceleration 80km/h and 100km/h can occur at any problem with the transmission. To test this hypothesis is very simple. Recommend to speed about 85 km/h, then depress the clutch pedal and monitor how the machine behaves. Turn on third gear and dump the clutch. Disperse with 50 miles on the last transmission box.

If the character beats will not change during all these activities, CAT is not guilty. If the level of vibration will increase with the box connected, then you can check out her involvement.

This method is also suitable to mechanical boxes, and automatic transmission. In the case of the machine at speeds of about 90 km/h to turn on the box 3.2,D,N, and then to monitor the transmission and car. Watch for vibrations. Most often wine boxes in the beat is minimal, but practice shows that such probability is.

What else to look for?

Vibration at high speed can be experienced due to unreliable mounting of the engine and exhaust parts. It is better to perform this check on the wound, and then plugged the motor. Also, there are times when shaking causes the damaged radiator fan.

Next, check attachments. Often the problem can be solved by replacing the drive belts or pulley balancing. Can't hurt to check the clutch basket and the flywheel. This can be done in the following way. Depress the clutch and set the selector to first gear. Next, start the engine and wait a few seconds. Then the lever is translated in neutral position, and the pedal is removed. Vibration still there? Look for a problem in the flywheel and the clutch basket.

CV joints in the front axles

Though It is not so popular reason, but it's pretty vulnerable spot, causing vibration at high speed – not uncommon. Experienced motorists recommend starting a diagnosis with this mechanism. The procedure must include a tactile check. In the presence of scratches – the CV joints replacement. It is better to replace this part in pairs.

To Summarize

So, among the frequent causes, you can highlight the attachment of the wheels, poorly recorded discs, warped driveshaft, constant velocity joints, hub bearings.

Vibration during acceleration from anything. The reasons are many. But if you try, they can be detected independently and not pay for diagnostic services in STO. But if you can't understand yourself, do not delay your decision indefinitely. It leads to bad consequences. With simple actions you will definitely find the causes of vibration on your car and eliminate them. Treat failures seriously, as neglect may be the cause of the accident.
