Any electronic product has a probability of problems, please check carefully before use, and use it after there is no problem. For example, the commonly used alternative tool car is a great industrial product assembled from various mechanical parts. Automotive assembly technology is more stringent, with a defined torque for each screw. Timely maintenance is also the protection of the car, and the problems of the car can be found in time. If you suddenly hear these two sounds while driving, I recommend that you pull over and check right away.
Please don't do the wrong thing. Most friends don't know cars, but need to know some basics. For example, before you have not driven for a long time or are ready to get on the highway, you need to check the condition of the car. "How to check this?" We're not experts either. The following points can be checked, such as tires. Observe whether there are obvious scratches on the surface of the tire and whether the air pressure is sufficient. Open the hood, observe the level of coolant and brake fluid, and add it as soon as it falls below the minimum. Pull out the dipstick to confirm the location of the oil, make sure all checks are correct, and then drive around.
The hub "bangs" after driving on the highway, there is a lot of user feedback. The interior of the vehicle is decorated with unusual sounds. Generally many models have the same problem, but this does not affect safety, normal driving can be. If you really can't stand the sound of abnormal decoration, go to the offline 4S shop for inspection and repair. It's not a fatal problem, but if there's a sound in the car, if you don't go to the 4S shop right away to check it, an accident is likely to happen. Tires are the most important part of the car, and if the tires have problems, they can't move forward. Pay more attention to the tires while driving.
When you hear the sound of the hub position shaking, you must be vigilant. There is a "bang" sound in the hub position, accompanied by a slight shaking, indicating that there is a problem with the hub's fixing. As a driver, you need to turn on the dual flash at this time and immediately lie down and stop. If an accident occurs because you didn't pull over immediately, you can't get it back. Parking was also for your own safety. In this case, the hub is basically loose, mainly because the screws are not tightened, or the violent shaking of the road surface leads to loosening.
The sound of rubbing the ground, there are also people who think that on time maintenance is the premise of ensuring safety, and on-time maintenance is to send money to the 4S shop, which is more than half a year behind. This way saves money, but it is not friendly to the vehicle. While carrying out maintenance, all vehicles are inspected with a computer. It's even clear which light isn't on. The engine chassis has a guard plate in the position. It is generally made of hard plastic, but the material may vary depending on the model. The screws on this protective plate are short and easy to fall off.
During operation, if there is a friction sound under the chassis, the screws of this protective device are likely to fall off, and half of the protective device is in a state of dislocation. In severe cases, the dropped part will rub against the ground. The faster the speed, the greater the friction, and the louder the owner hears. After hearing such a sound, it is also necessary to immediately pull over and look down at the chassis. Whether it is a problem with the protection plate. If you are not a sanitation worker, you must stop. After the vehicle has passed the 4S inspection, it can ensure safe driving.
Conclusion: In normal driving, the vehicle will not have problems. Some people drive all their lives and haven't had problems. Cars tend to be very robust and stable, and these two problems rarely occur. But don't be afraid of ten thousand, just in case, your own life safety is the first. If you find that your car is not right, it will behave differently than usual, and there must be something wrong with it. Be sure to go to the 4S shop for inspection, correct the problem in time, do not neglect!
