Why is crank pulley wobbling?

Crank pulley wobbling can occur due to several reasons, including a worn or damaged crankshaft, misalignment of the pulley, or a failing engine mount. Additionally, a loose or damaged harmonic balancer can contribute to this issue. It's essential to address the problem promptly, as it can lead to further engine damage or belt misalignment. If you notice wobbling, it's advisable to have a technician inspect the engine components.
