The steering wheel of the car is shaking. What problems may exist?

First, the car shakes the steering wheel while waiting for speed. When the car is idling, it is found that the steering wheel has obvious jitter, which can be handled like this.

1. Replace the car spark plug. Engine spark plugs are caused by embrittlement of insulating parts used by the engine for a long time, which leads to poor secondary flashover or flashover performance, which leads to unstable operation of the engine, so the steering wheel of the automobile will shake.

2. Replace the engine fuel. The engine burning oil is not very good, which will also cause the idle steering wheel to shake. Poor quality gasoline will burn insufficiently. In addition, after the gasoline of this engine enters the cylinder, it is very easy to be absorbed by carbon deposits, which will lead to the car engine not reaching the best state, and of course it will also lead to jitter.

3. Clean the throttle. If the carbon deposition of electronic throttle is serious, the opening of electronic throttle will be inaccurate, which will lead to engine thermal jitter. If the engine is still shaking after the electronic throttle is cleared, there may be a problem with the total distance of the electronic throttle. At this time, it is necessary to go to the car 4S shop to replace it. Remember to replace the parts assembled by the original factory to make the car match better.

Second, the steering wheel shakes when the car is driving. The steering wheel jitter when the car is driving should be divided into different driving conditions. At the speed of 30-40km/h, the downward wheels shake and the car body shakes. If these problems occur, it is usually due to wrong operation or the deformation of automobile tires due to too long use. At this time, just replace the new wheels.

When the vehicle speed is about 80 km to 90 km, the steering wheel will shake, and it will recover after more than 90 km. This happens mostly because of the deformation of automobile tires or the reduction of the influence of transmission devices. It is necessary to check whether the precise positioning angle and toe-in of the front tire meet the requirements. If a return error is found, it must be adjusted. At the same time, it is necessary to check the dynamic balance of the wheel rotor and whether the deformation of the automobile tire is too large. If there is a problem, it must be replaced.

Third, the steering wheel shakes when the car brakes the pedal. If it is a car that has run more than 50,000 kilometers, then you need to check whether the brake pads of your car are getting thinner and thinner. If the brake pads of the car are really soft, they must be replaced with new ones. If replacing the car brake pads has not solved the problem, it is necessary to check the brake pads. The brake pads are deformed for a long time, causing the steering wheel of the car to shake and the hands to shake. The brake pads can be replaced immediately, and the shaking problem can be solved immediately. However, the cost performance of brake pads is not high. You can take them to places with CNC lathes and equipment for testing.

In addition, if you step on the brake pedal at high speed and the steering wheel shakes, it may also be that the automobile transmission is abnormal. At this time, it is best to check whether the steering tie rod and the steering tie rod ball cage are rusted or loose.
