In the static state, we can take the following methods: check the left and right sides of the rear wheel respectively, and the right side is a line, not a straight line, indicating the overall frame; the measurement of the gap between the rear wheel and the wheel cover should be roughly the same, or the overall interpretation Check the hood and wings for signs of frame or bend clearance; check the door and fender seams, door and door clearances, if the gap is asymmetrical, the hood and doors may need to be replaced, which of course is related to the accident. Open the used car engine cover and look at the two longitudinal beams of the entire engine room and check that they have no traces of welding or cracking. If this is an end or side impact accident, the frame is squeezed and bent or cracked and both require welding repair. If the condition of the lifting frame, you can check out the obvious, because the vast majority of car chassis, as the ribs pass before, you can determine whether there are any accidents through the ribs are not straight and strengthen the inspection.
