A 2009 mileage Honda CR-V car with mileage mileage of about 138 thousand km, equipped with 2.4L engine and 5 forward automatic transmission. Customers complain that they tend to turn around at a time when they are heavy and sometimes have the force to rebound, and occasionally click "click". After receiving the car: first of all, the trial run confirms the fault phenomenon, and finds that when turning, it is really heavy and heavy, but it does not hear the abnormal sound, nor does it realize the resilience. Another trial run with customers failed to reproduce the abnormal sound. Then check the steering oil level in the steering oil cup, find the lowest line below the scale, and find the steering pump oil, and the pump is covered with a layer of oil dust. No exception was found in other parts of steering system such as steering gear and booster tubing. As the customer complained about the difference, the lift vehicle checked the chassis, and found the clear amount of the ball head on the right front side of the rod. It was a preliminary judgement that this was the source of the complaint of the customer. With the consent of the customer, the steering pump and the right front stabilizer rod are replaced, and the auxiliary oil is added to the normal level to test the car. It is found that the steering is still light when the steering is still, and there is little difference from before the replacement. At the same time, there is no different noise. Through communication with customers, this car often goes in and out of the building. According to this information, the bad driving conditions of the construction site may cause a slight deformation of the gear rack of the steering system, causing the steering to sink in light. The replacement of a steering gear test is still not improving. But only repeated turn to turn to the test steering system. When you turn slowly to the right, you hear a click. The stethoscope confirmed that the sound was emitted from the front shock absorber top. To check the right front shock absorption, it is found that the top rubber has been worn through the damping spring, and the right front shock absorber is replaced. The test car is no longer light when the steering is no longer, and the car is delivered to a customer. After the follow-up visit, the noise of customer complaints and the phenomenon of turning rebound have not appeared again.
