Presumably, many people have their own cars, but they don't know much about their cars. Next, let me talk about the inspection method of the rear axle and rear suspension of the automobile. Because we only know a certain knowledge of automobile inspection, we can ensure our safety during driving and minimize the accident rate, which not only ensures the safety of people on board, but also ensures the safety of other vehicles. First of all, I want to talk about the inspection of the rear axle of the car. Before the inspection, we must lift the car to facilitate the inspection. We mainly check the deformation and welding damage of the automobile rear axle body. Because the rear axle of our car is a very important part, it is absolutely not allowed to repair the axle and beam of the rear suspension system by welding, which means that the rear axle of our car can only be replaced, but not repaired by welding. If the automobile rear axle is found to be deformed and welded, it should be replaced in time. In addition, we only use rubber to check the wear and aging of metal bushings. If the aging is serious, it must be replaced in time. In fact, this inspection is very simple, just watching, and there is no technical content at all. Let me talk about the checkpoint of the rear suspension. First of all, it is necessary to check the rear shock absorber, visually check whether there are cracks in the rear shock absorber and whether the shock absorber leaks oil. If there is leakage or crack, it is recommended to replace it in time. At the same time, check the rubber parts and springs to see if there are any damage or cracks on the surfaces of the rubber parts and springs, and replace them if there are any. The above inspection methods are very simple, and they are all carried out through the appearance. I think it is very necessary to check the rear axle and rear suspension of the car, so as to ensure the safety of our driving, so it is very good to know some automobile knowledge. In this way, when the car breaks down, we can accurately judge where the car breaks down, so as to carry out targeted maintenance and reduce costs.
