One problem related to axle hubs has been reported for the 2004 Dodge Ram 2500. The most recently reported issues are listed below.
My 2004 Dodge Ram 2500 developed a vibration in the front end a about 35,000 miles. It was most noticeable at low speeds turning to the left. It got worse and by 50,000 miles began to appear at speeds from 45 mph and up. At 52,000 miles the dealer found that both cv joints were bad along with both upper and lower ball joints. Both cv joints, all four ball joints, and the lt front hub and bearings were replaced. I have the replaced parts except the cv joints which were returned to Chrysler.
