Summary Verdict

The 2002 Dodge Ram 3500, particularly with the 5.9L Cummins diesel, is a durable truck with a reputation for longevity. However, owners should be aware of potential issues with the VP44 injection pump and, less commonly, cracked cylinder heads on the diesel. The V10 gasoline engine can experience intake manifold leaks and spark plug blow-out. Automatic transmissions (47RE/48RE) may develop torque converter or overdrive issues, while the NV4500 manual can suffer from synchronizer wear. Suspension components like ball joints and leaf springs are common wear items. Electrical gremlins, often related to the BCM, and rust on body panels are also points to consider. Despite these potential concerns, with proper maintenance and timely repairs, the 2002 Ram 3500 remains a capable and reliable heavy-duty vehicle.
