Compared with the new trailer, the second-hand trailer has low price and fast cost recovery. It is not much different from the new trailer in basic functions, and it can also save a lot of processing time. Therefore, many car owners tend to buy second-hand trailers when buying cars.

However, the second-hand trailer is not a new car after all. It may lead to many hidden problems due to the non-standard use in the early stage. If the owner accidentally looks out of sight and wrongs the money, he may face many troubles in the follow-up.

Today, Darong axle summarized some experience of some old drivers when buying second-hand cars to help you "avoid the pit".

1. Check the qualifications of vehicles. The most important step in selecting a car is to pay attention to the relevant qualifications or procedures, such as vehicle registration certificate (or original invoice), driving license, vehicle purchase tax payment certificate, road maintenance fee procedures, compulsory insurance, engine nameplate, gearbox nameplate, frame number, vehicle nameplate, certificate of conformity, etc.

Check whether the data are consistent to see whether the vehicle belongs to an individual household or a company household. If the vehicle registration certificate and driving license are missing and not reissued in time, the vehicle may be a "black car". If there is a problem of arrears in the payment of compulsory insurance and vehicle maintenance fee, the buyer will increase a large amount of expenditure. In addition, additional attention should be paid to the issuing time, which can infer the real year of the vehicle.

2. Check the three major parts of the vehicle. This is the focus of second-hand car selection. We should pay attention to whether the three major parts of the vehicle are original and damaged, whether the engine and gearbox leak oil, whether the chassis girder is deformed, and whether there are differences in screws of the same model on the girder, so as to judge whether they have been repaired. Don't be too troublesome. After all, buying a second-hand car costs a lot. If necessary, you can start the cab or climb under the frame for inspection.

3. Check the vehicle leaf spring and rear axle. The rear axle and leaf spring of the trailer are the key to the bearing capacity of the vehicle. You can check the number of leaf springs and the wear degree of the upper and lower fixed positions of the leaf spring to judge the previous use of the vehicle. For the rear axle of the vehicle, pay attention to check whether there are cracks or welding traces. You can measure the track width of the rear axle with a ruler to compare the vehicle registration certificate with the certificate of conformity, so as to avoid the modification of the vehicle and affecting the performance of parts and components.

It is worth noting that there are many parts of the rear axle, many of which can not be distinguished by the naked eye, but have a great impact on subsequent use. Therefore, it is recommended that owners who buy second-hand cars should try to replace the rear axle with a new one. Now there are many brands of car bridges in the market, including those with reliable quality and relatively affordable price. For example, Darong car bridge is very suitable for car owners with low budget.

4. Check the vehicle name and brand. The manufacturing date on the vehicle nameplate can be checked with the frame number on the girder, or judged by the tenth digit code in the vehicle identification code.

5. Check the windshield with the vehicle production date. Generally, the last two digits on the code at the bottom of the windshield represent the production date. If this date is later than the vehicle production date, it indicates that the windshield may have been replaced.

6. Check the body paint. Under normal circumstances, there will be more or less color difference in the later repaired car paint, the level of sheet metal technology is different, and the flatness of the paint surface will be different from that of the original factory. You can judge whether the vehicle has been scratched or collided by checking the painting of front and rear bumpers, cab doors, front covers, body, etc. you can also check whether there are grinding marks on the lights.

7. Check the cab. When looking at the car, remember to observe in detail whether there are welding marks inside and outside the cab. You can open the soft bag decoration, so that you can check it more clearly. If the cab of the vehicle is damaged due to an accident and needs to be cut and repaired, there will generally be welding traces. This later welding may lead to problems such as loose sealing and noise.

8. Check the host screws carefully. The screws used by different main engine manufacturers are also different. Generally, corresponding indications will be printed, and the original screws that have not been disassembled will not rust. These two points can be used to judge whether the parts have been disassembled.

9. Check the vehicle sound. For example, whether there is abnormal noise when the door is opened and closed, whether the engine sound is normal, and whether the sound of knocking on the tire is qualified. Of course, this also requires some experience, so novice car owners had better bring friends who understand the car when buying a car, or try the model or engine of the same model and brand before buying a car, and then make a comparison.

10. Check the illegal records. Many second-hand cars for sale in the market have untreated traffic violation records. Once buying such cars, consumers will be "responsible" for the traffic violations of the former owner, otherwise they will not be able to transfer the ownership of the vehicle.

11. Before buying a second-hand car, you must be clear about what kind of car you want to buy, what kind of goods to transport, how much budget, and the wide range of options for the market price and types of second-hand trailers. As a result, many owners who do not know what car they want to buy do not know what they want to buy when they see so many five flower eight door cars in the second-hand car market. Once this happens, the result can only be that they are led by the nose by car dealers, and they find that they don't like it when they buy it home.
