Power Train Driveline problems of the 2008 Dodge Caravan

Chrysler had a recall on many of their minivans built in January 2008, for replacement of the front hubs and wheel bearings. My 2008 Dodge grand Caravan had a wheel bearing go out at 35,000 miles and was replaced under warranty. I have asked why my van is not on the recall. No one seems to be able to explain. I now have almost 50,000 miles and the only warranty is the lifetime power train warranty. It is starting to make the noise again intermittantly. I don't trust this vehicle.
