How to judge whether the injury has damaged the chassis, and the chassis needs to be repaired if it is scratched?

If there is oil seepage or insignificant abnormal noise after hitting it, it may indicate that the chassis is damaged. If the position of the structural column of the car chassis is bumped, the coating will be scratched or even exposed to the metallic luster. If it is not handled in time, the chassis will be seriously rusted. When the chassis of the car is hit by an unknown object, it is impossible to judge whether there is damage. It is recommended to drive the car to a 4S shop or repair shop for inspection.

How can you tell if the damage is done to the chassis?

If it is found that there is oil seepage or no obvious abnormal sound after hitting it. Lift the car with a jack and inspect the chassis for scratches or damage. If the steel plate is painted, spray some paint. If the pipeline is damaged, go to the 4S shop for inspection and maintenance. There is no major damage to the chassis, which can be judged by the driving situation of the car. After the chassis was smashed, the car did not make any abnormal noise or deviate during driving, and the fault light did not light up, so there was no problem with the car. If the above problems do not occur, if you are still worried about the car, you can go to the 4S shop for a detailed inspection. As a saying goes .Sand and standing water on the road will cause great corrosion and damage to the chassis, so pay attention to the protection of the chassis and avoid damage.

The chassis is scratched and needs to be repaired?

Depending on the degree of damage, minor bumps do not require maintenance, and serious scratches require maintenance. The chassis of the car has been bumped for many times, and because there is no sunlight all day long, the hidden danger of corrosion and damage is very large. And because the most vulnerable parts of the car chassis are the oil pan and oil pipes, if oil seeps or unknown noises are found after knocking, it may indicate damage. Oil pipes, while vulnerable to bumps, are hidden in grooves in the chassis steel plate, protected from being above the level of the chassis. In addition, the steel oil pan is not so easy to break, as long as it is not particularly noticeable scratches.
