I know it is not a Ranger but I wanted to ask your guys' opinion. My dad has a 2000 F-150. The starter grinds every once and a while which now seems to be getting worse. To fix it when it grinds you have to put it in neutral, roll it forward, and then put it back into gear when you are rolling. Then hopefully it will start. We have already replaced the starter on it and it did not help. Anyone else ever have this problem or no someone that has? Could it be the flywheel?
