Summary Verdict

The 2000 Dodge Ram 4000, particularly with the 5.9L Cummins engine, is known for its robust powertrain, but specific components like the VP44 injection pump and lift pump are common failure points that require attention and potential upgrades. The V10 engine can also experience intake manifold and spark plug issues. Manual transmissions, especially the NV4500, can develop issues with 3rd gear, while automatics like the 47RE may need torque converter or internal clutch pack repairs. Suspension components like leaf springs and ball joints are subject to wear due to the truck’s heavy-duty nature. Electrical issues, such as alternator failure, and body rust are also considerations for this model year. Overall, while capable, proactive maintenance and awareness of these known issues are crucial for long-term reliability.
