Hi all professional,
i buy a used car from a friend. when I push the pedal to accelerate from still(RPM 1000-2000), i can hear clearly there is a noise from front and the bottom of the car (same source). It is a noise obviously generated by metal clashing with each other. But such noise doesn’t appear when the car hit big holes on roads or when the RPM is higher than 2000RPM. the car goes smoothly and quietly on highway, but the noise worries me.
please let me know how to eliminate such car issue.
