PLZ HEEELP!! Hi this is my first time on this page. And it seems everyone is really helpful. I have a 2007 Titan 2wd and lately I've had an awful vibration on the engine that makes my fan clutch vibrate and hit my fan shroud.the vibration comes up when I rev my engine while on park. And on the road a little Over 3000rpm. I have already replaced the fan clutch mount, fan clutch, fan, and pulley bearings. But still have the same vibration I need help because I've already broken two fans.
