One problem related to axle shaft seal has been reported for the 2004 Dodge Ram 3500. The most recently reported issues are listed below.
2004 Dodge 3500 truck front l/h wheel hub assy bearing came apart at 70 mph causing the truck to cross over 2 lanes of traffic and into oncoming traffic. Dodge dealer told me this is a problem. But it cost me 350 dollars this to me is a safety issue and a customer should not have to pay the cost or die due to this.
