Does anyone know if engines replaced by the factory (in 2007) had an upgraded IMS bearing to prevent failure or was it just a replacement with another engine that is prone to failure?
I'm looking at a 2004 Anniversary that had the engine replaced in 2007. I was told that it had an updated IMS from the gentleman selling it but two different dealers don't think that that is the case.
