As far as the actual knuckle goes, it should be fine. If it comes with a ball joint, let's be honest Any ball joint can fail early. I don't know the difference in price between the Motorcraft and the Mevotech but if it is over $100 I would go with the Mevotech. Ball joints are a maintenance item and occasionally need to be replaced. Even OEM ones. Save your money and take your SO out to dinner on the savings.
