1, in 1400-1500 around the time of abnormal sound. Abnormal sound is more obvious in the case of high power consumption such as air conditioning, uphill and turning.

2, rapid acceleration noise, resonance phenomenon, insufficient power.

3, the car driving tension wheel damage, there will be no brake no direction phenomenon.
