Car shaking is one of the common problems in cars,Although it seems "not serious",It only affects our driving mood,But often there are big problems hidden behind this "small problem",If the fault is not eliminated in time,It is very likely to cause greater hidden dangers,It will be too late to regret by then!Today I will talk to you about the culprits that cause "car shaking"。

First of all, we have to distinguish whether our car is shaking from the body or the engine,The distinction is also very simple。If the car is still vibrating when you turn on the ignition,Then it can basically be determined to be engine vibration。And if the car starts shaking after starting,The cause of the shaking can be determined to be the body shaking。


Cause of vehicle body shaking


There are not many reasons for vehicle body shaking,It can basically be determined that it is a chassis problem,The chassis problems that will affect body vibration are the following:


1. The brake disc is uneven

Picture


Because the car owner’s driving habits are bad,Frequently heavy braking、Sudden brake,This may lead to problems such as uneven consumption and deformation of the brake disc。You won’t notice it when driving,But every time you step on the brakes, the body will shake and the brakes will bounce.。If you go to a repair shop for repairs, you will usually choose polishing and repair,If the wear is serious, it may be replaced。


2. Steering mechanism failure

Picture

Problems with the steering mechanism can also cause the car to vibrate,Especially cars with hydraulic transmission systems,If there is a loss of power steering oil,When the steering device fails,The car is likely to vibrate while driving。The elimination method is,The shaking of the car is generally caused by the steering mechanism,The steering wheel will also vibrate,Once the source of the fault is determined,Go to the repair shop、Just ask professionals at the 4S store for repairs。


3. The driving half shaft is not concentric

Picture


If the half shaft is deformed、When there is a fault such as bending,It will cause the two driving half-shafts to not be on the same axis。This situation usually occurs when the car is idling and there is no problem,It shakes as soon as it is turned on,No problem when returning to idle speed again。If your car shakes like this,Then you can check the half shaft。


Causes of engine vibration: The cause of car vibration is mostly caused by engine vibration,As the name suggests, the problem of engine vibration all occurs in the engine,The following are common failure points:


1. Lack of cylinder and lack of fire

Picture


This is the most common cause of engine vibration,Not even one,The problem is with the seabet ioengine ignition coil or spark plug,If there is a problem with the ignition coil or the spark plug fails to spark for some reason,The car will vibrate。Cylinder shortage is also a relatively easy fault type to judge,As long as the car is shaking more than usual when running at medium and low speeds,And there will be a feeling of weakness in acceleration,Then it can basically be concluded that the engine is missing a cylinder。



2. Severe carbon deposits in the cylinder

Picture


If serious carbon accumulation in the cylinder causes the engine spark plug to become clogged、If the valve is blocked,The problem of engine vibration will also occur。If the car’s acceleration ability is not as good as before,If the jitter is very persistent,Then you can consider cleaning the engine cylinder。


3. Circuit problem

Picture


Everyone knows,There are many sensor devices on the engine that are responsible for transmitting engine signals,such as crankshaft sensor、Knock sensor, etc.,And if there is a problem with these sensors,It may cause engine air intake、The fuel injection is affected by a bad one,It is also very possible that the engine is shaking。


4. Aging of engine foot pads

Picture


This is also a very common cause of jitter,If your car’s engine shakes more and more seriously,But the power has not weakened,You can consider whether it is a problem with the machine feet。


Summary:The above are some of the more common types of faults that cause "car shaking",Recommended for friends to collect,If the car shakes, take it out and take a look and analyze it yourself,To avoid being fooled by the repair shop, I cleaned the throttle several times to no avail。Do you think so?
