With the increasingly developed high-speed network in China, many car owners will choose to go to the high speed for the first time when traveling long-distance, after all, many advantages such as good highway conditions and fast speed are incomparable to national highways. Although the expressway provides convenience for the majority of car owners and can greatly shorten the driving time, the danger of the highway is also quite large, especially the uncontrollable factors caused by the fast speed are too many, which may lead to serious traffic accidents at any time.
Fortunately, when the car fails, there will be some special precursors, if it is not properly checked, it is very likely to cause danger, if the car on the road when the two sounds, the traffic police remind: stop immediately, be careful of car destruction and death!

Precursors to car failure
Listen to the sound to judge the wheel hub loose
When lightly pressing on the brakes of the car, if you hear a slight "snort" or "click" sound in the car, 80% of the wheels are loose. After hearing the abnormal sound, be sure to find a safe place to stop the car in time, carefully check whether the wheel hub is loose, and then drive on the road after reinforcement.
Listen to the sound to judge that the hub screws are loose
Generally when the wheel hub screws are loose, we gently step on the brakes when we are driving downhill, the car tires will have a small bumping sound, if it is the rear wheel screws of the car tires are loose, then the sound of the rear wheels will be amplified through the trunk.
Secondly, if we find that the driving is unstable in the process of driving, and the handling is not good, observe the driving car in the back and find that the wheels are rocking back and forth. When driving at low speeds, we can hear a noticeable clicking sound, and we should stop driving immediately and check the wheel screws of our car.
There are many car owners who are likely to think that this amplified sound is caused by the inertial collision of objects in the trunk, so they will not care about the loosening of the wheel hub screws. If we are misled by this illusion in the long run, we will certainly pay a heavy price one day.
Real Case:
On April 4, 2021, Li Mou drove a large truck on the G15 Shenhai Expressway when a tire on the right rear side fell off in the driving lane. As a result, when another truck was driving to the place, due to emergency avoidance, it suddenly crossed the central guardrail and collided with a large bus on the opposite side, causing the bus to overturn, resulting in 7 deaths on the bus, 19 injuries, and the death of 2 occupants on the truck.

How to prevent wheel failure
Before driving, we all take a minute to look at the place where the car can see, see if there are any abnormalities, or do a regular check, if your car often drives at high speed, this will improve the inspection.
Uneven road speed should not be too fast
Try to choose a smooth road to drive, in the uneven road speed must not be fast, drive slowly, encounter roadblocks also have to drive slowly. This is the main reason for the damage to the wheel hub, which is generally invisible to the naked eye after the wheel hub damage, and slowly forms a safety hazard.
Secondly, the best way is not to wipe the curb, but this is not realistic for friends who drive often, but if you avoid it, you must try to avoid it.
In short, when you are driving on the road, you must pay more attention to the strange noise emitted by the car, especially the two sounds mentioned above, once the fault is not solved in time, not only will the car accident kill, but also the owner of the car that may be involved in other lanes will be injured, so everyone must pay attention to check the state of the car.
