One problem related to front suspension wheel bearing has been reported for the 2003 Dodge Ram 3500. The most recently reported issues are listed below.
Driving at the posted speed limit, without warning, the truck made an abrupt lane change then I managed to gain control. What happen is that on this vehicle, the wheel bearing assembly is one piece and can't be greased or maintained in any way. It heated up and locked the front wheel causing a serious and violent turn at freeway speeds.
