Problem overview

Some Mitsubishi Montero Sport owners report experiencing loud bangs while driving, which could indicate several potential issues. For instance, broken harmonic balancer bolts may lead to significant engine vibration and noise, resulting in a loud sound from under the hood. Additionally, some owners identify suspension problems as a source of these noises, often linked to the need for replacing parts like wishbone bushes, track rod ends, and drop links. Steering issues, such as worn-out components or misalignment, can also contribute to unusual sounds while on the road. It is crucial for owners to address these issues promptly to ensure vehicle safety and proper functioning, and to consult a qualified mechanic for effective diagnosis and resolution.
