Why does the car body shake when braking in D gear?
1 Answers
The reasons for car body shaking when braking in D gear are as follows: 1. It is normal for the car body to shake when braking in D gear. In D gear, the vehicle is in a power connection state. The engine power is transmitted to the transmission, and then the transmission transmits it to the wheels through the drive shaft. The vehicle should be in a forward state, but stepping on the brake is equivalent to the transmission being restrained, thus causing the car body to shake. 2. Abnormal shaking may be caused by damage to the engine mount. There is an engine mount component between the engine and the frame connection point, which is made of rubber and can buffer engine vibrations. Rubber products will also age after long-term use. When the engine mount ages and hardens, it causes the engine vibration to be directly transmitted to the car body. 3. It is recommended not to stay in D gear and brake for a long time, as it can cause certain damage to the transmission. If waiting at a red light, in addition to avoiding staying in D gear and braking for a long time, do not shift to P gear to prevent rear-end collisions from causing significant damage to the transmission as well.
