Recently, many friends have been asking about his car. It has been driving for some time, but recently it has been a bit bumpy and shaking, but I don't know where the problem is.

Car shaking is one of the most common faults in cars, which can be divided into shaking during idle and shaking during driving. What is the car shaking? What is the reason for the shaking? Let's analyze it briefly together

To solve car shaking, the first step is to distinguish between body shaking and engine shaking, and the differentiation method is also very simple. If the car has been shaking since you ignited it, it can basically be determined as engine shaking. If the car only starts shaking after driving, then the cause of the shaking can be determined to be the body shaking.

The reason for body shaking

There are not many reasons for body shaking, and it can be basically determined that it is related to chassis issues. The chassis problems that can affect body shaking are as follows:

1. Uneven brake discs

Due to poor driving habits of car owners, frequent heavy and sudden braking may lead to uneven consumption and deformation of brake discs. You may not notice it when driving normally, but every time you step on the brake, it will be accompanied by body shaking and brake pedal bouncing. If you go to a repair shop for repairs, you usually choose to polish and repair it. If the wear is severe, it is also possible to replace it.

2. Steering mechanism malfunction

Problems with the steering mechanism can also cause car shaking, especially for cars with hydraulic transmission systems. If there is a loss of steering oil and the steering device malfunctions, the car is likely to experience shaking while driving. The solution is that the shaking of the car caused by the steering mechanism is usually accompanied by the shaking of the steering wheel. Once the source of the problem is determined, go to a repair shop and find professional personnel for repair.

3. The drive half shaft is not concentric

If there is deformation, bending or other faults in the half shaft, it will cause the two drive half shafts to be not in the same axis. This situation is generally manifested when the car is idling without any problems, shaking immediately upon driving, and then returning to idle without any problems. If your car is shaking like this, you can go check the half axle.

Reasons for engine shaking

The reason for car shaking is mostly due to engine shaking, and as the name suggests, engine shaking problems all occur on the engine. The following are common fault points:

1. Lack of cylinder and misfire

This is the most common cause of engine shaking, and even one of them is not. The problem lies in the ignition coil or spark plug of the engine. If there is a problem with the ignition coil or the spark plug cannot jump for some reason, the car will experience shaking. Lack of cylinder is also a relatively easy type of fault to determine. As long as the car shakes a lot more than usual when running at medium and low speeds, and there is a feeling of weak acceleration, it can be basically determined that the engine is out of cylinder.

2. Severe carbon buildup in the cylinder

If severe carbon buildup in the cylinder leads to engine spark plug blockage and valve blockage, engine shaking will also occur. If the car's acceleration ability is not as good as before and the shaking is very persistent, then you can consider cleaning the engine cylinder.

3. Circuit issues

As is well known, there are many sensor devices on the engine that are responsible for transmitting engine signals, such as crankshaft sensors, knock sensors, etc. If these sensors have problems, it is possible to cause adverse effects on engine intake and fuel injection, and engine shaking is also likely to occur.

4. Aging of engine foot pads

This is also a very common cause of shaking. If your car's engine shaking becomes more and more severe, but the power does not weaken accordingly, you can consider whether it is a problem with the engine floor mat.

Summary: The above are some common types of faults that cause "car shaking". If your car has abnormal shaking, you can compare and find the cause on your own.
