What is the Knocking noise at left front wheel?

A knocking noise from the left front wheel could indicate several issues, such as a worn-out CV joint, loose or damaged suspension components, or a failing wheel bearing. It may also result from debris lodged in the brake system or issues with the brake pads. It's important to have a qualified mechanic inspect the vehicle to diagnose and address the problem promptly, as ignoring it could lead to further damage or safety concerns.
