Did my '05 Dodge Caravan 2.4L originally come with an OAD pulley pre-installed on the alternator? Been trying to diagnose a vibration/noise problem and I suppose this must be the problem. I replaced the alternator.

If so, anyone have a link for a replacement alternator with an OAD pulley already installed?

 

Or the part number for the Litens OAD I need?

 

A Rep from Tendeco/Litens confirms my model year was not originally equipped with a Litens OAD...
