ダイハツ　ウェイク　LA700S　車全体に振動が！？修理します！！

2016 model, 99,900 km on the odometer. When accelerating, "an unpleasant vibration that makes the whole car shake!" More recently, cars have a "self-diagnosis function" that helps identify the cause of a malfunction. Even when I connected a diagnostic tool to check the code, the error code was 0... Mechanical malfunctions that don't produce an error code take a long time to identify.↓↓ So what was the cause of this malfunction? Please take a look!
