Have a nocking noise on left side wheel?

A nocking noise from the left side wheel could indicate a few potential issues, such as a loose or damaged brake component, a worn wheel bearing, or a problem with the suspension system. It's important to inspect the wheel assembly, brakes, and suspension components for any signs of wear or damage. If you're unable to identify the cause, it's advisable to have a professional mechanic assess the situation to ensure safe operation of the vehicle. Ignoring the noise could lead to more serious problems down the line.
