Two problems related to power train driveline have been reported for the 2004 Dodge Ram 3500. The most recently reported issues are listed below.
Noticed a vibration when reaching speeds over 72 miles per hour. Contacted local dealer regarding problem. The first time the truck was in for service the local dealer decided to put in a new drive line and aligned it. After this service the vibration still existed. Soon after the truck stalled in the middle of a very busy highway due to a malfunctioning fuel injector pump. I believe this was caused by the ever present vibration. Second time local dealer saw the truck they replaced the fuel injector pump and tried to re-align to fix the vibration. This still didn't solve the vibration. A review of the complaints on this site it appears that this is a nation wide problem and defect in this truck. Ak.
Vibration in the drivetrain at high speeds, starting at about 72 miles per hour. 6 attempts of balancing drive train and wheels have not solved the problem. Vibration is enough to numb hands and feet and distort the rear view mirror images.
