What causes the abnormal noise when starting on a slope?
1 Answers
Possible causes of abnormal noise when starting a car on a slope are as follows: 1. Clutch noise. 2. Transmission shaft support bearing noise. 3. Drive axle abnormal noise. 4. Differential noise. 5. Tire noise. 6. Vehicle resonance caused by loosening of a certain part. The abnormal noise during starting and acceleration is most likely due to low-speed engine resonance. Low-speed vibration frequency is low, and when it is close to or the same as the natural frequency of certain components, resonance will occur. If the car has been driven for too long, the original fasteners and rubber washers may age and loosen, which can easily lead to increased vibration.
