**Cummins** is not spelled with a "g"... Clessie never changed the spelling of his name. I know, your finger slipped on the keyboard ;]
So, what does 'newer' mean in your mind? ...2010? ...2007? ...2004? the isx used no-lash gears up until 07 which would cause some crazy geartrain noise after about 500,000 miles. rough running is often fuel system problems such as injectors and actuators
