What Causes the Abnormal Noise in BMW 3 Series While Driving?

[LaJaxson]

BMW 3 Series abnormal noise while driving is caused by body resonance or abnormal wear of the wheel hub bearings. Automobile Resonance: Resonance is a frequently used term in physics, referring to a physical system vibrating with greater amplitude at specific frequencies compared to others. These specific frequencies are called resonant frequencies. At resonant frequencies, small periodic vibrations can produce large vibrations because the system stores kinetic energy. When resistance is small, the resonant frequency is approximately equal to the system's natural frequency or inherent frequency, which is the frequency of free oscillation. Abnormal Wear of Wheel Hub Bearings: Address the issue promptly by repairing or replacing the wheel hub.
