While the mechanic mentioned that the CV joints are fine and the power steering pump is not leaking yet, it's still important to thoroughly diagnose the issue to identify the exact cause of the knocking and wobbly steering. It may be necessary to perform additional tests or inspections to narrow down the problem. Having a qualified mechanic inspect the vehicle and provide a detailed diagnosis is recommended to ensure your safety and the proper repair of the vehicle.
