The 2004 Ford F-350 Super Duty is a heavy-duty full-size pickup built for towing, hauling, and demanding work use. It’s ideal for contractors, ranch and farm owners, and RV or trailer owners who need high payload and strong towing capability in a long-lasting chassis. For 2004, the F-350 sits in the Super Duty lineup as the one-ton class option above the F-250, offering stouter suspension, available dual rear wheels, and big-power engine choices. This model year is part of the 1999–2004 Super Duty generation, known for its rugged frame and broad configuration range.

- Heavy-duty Super Duty platform: Fully boxed front frame sections and robust underpinnings designed for high payloads and frequent towing, with single rear wheel (SRW) and available dual rear wheel (DRW) setups. - Engine options for 2004: Common choices include the 5.4L Triton V8, 6.8L Triton V10, and the 6.0L Power Stroke turbo-diesel V8, paired with automatic or manual transmissions depending on configuration. - Towing and work-ready configurations: Regular Cab, SuperCab, and Crew Cab body styles, plus multiple bed lengths to match jobsite or RV needs. Many trucks were optioned with tow packages, trailer wiring, and integrated brake controller provisions depending on trim. - 4x2 or 4x4 capability: Available four-wheel drive with a truck-focused transfer case for traction in snow, mud, and work sites, making it a popular choice in rural and northern markets. - Strong aftermarket and parts availability: Because of the Super Duty’s popularity, it’s easy to find suspension, towing, and utility upgrades, along with widely available replacement parts for both gas and diesel models.

Shoppers often search “2004 Ford F-350 problems” and “2004 Ford F-350 common issues” because reliability varies significantly by engine and maintenance history. Overall, a well-maintained gas F-350 can be very durable, while the 6.0L diesel can be dependable when “sorted,” but may be expensive if it hasn’t been maintained or updated. 1) 6.0L Power Stroke EGR and oil cooler failures: A frequent complaint involves the engine oil cooler plugging, which can contribute to EGR cooler failure and coolant loss/overheating. This is often reported anywhere from 80,000–150,000 miles depending on maintenance and driving conditions. 2) Head gasket and head bolt concerns (6.0L diesel): Elevated boost, overheating events, or neglected cooling systems can contribute to head gasket issues. Symptoms can include coolant pushing out, degas bottle venting, or repeated overheating, commonly appearing around 100,000–200,000 miles on higher-stress trucks. 3) Injector and high-pressure oil system problems (6.0L diesel): Stiction, rough starts, misfires, and hard hot starts can trace back to injectors, FICM voltage issues, or high-pressure oil leaks. These can show up around 90,000–180,000 miles and may be worse in cold climates or with infrequent oil changes. 4) Front suspension and steering wear (all engines, especially 4x4): Tie rods, ball joints, track bars, and steering dampers can wear, leading to looseness, wander, or vibration. Many owners address this between 80,000–150,000 miles depending on tire size, road conditions, and payload use.
