What is the 2003-2010 Ford F-350 5R110W TorqShift Torque Converter Failure and Low/Reverse Planetary Pinion Walk-Out?
The 5R110W TorqShift used in 2003-2010 F-350s has two documented failure modes that matter to heavy-duty owners. The stock torque converter uses a stamped-steel shell and a single-disc lockup clutch that is marginal behind a loaded F-350, particularly a dually pulling a gooseneck… Repairs typically run $2,800-$7,000. Severity: high.
What is the 1999-2025 Ford F-350 Death Wobble - Violent Steering Oscillation?
After hitting a bump at highway speed, the front end enters violent steering oscillation (death wobble) that requires slowing to a stop to recover. Caused by worn front-end components: track bar bushing, ball joints, tie rod ends, or steering damper. Repairs typically run $200-$1,500. Severity: high.
What is the 2008-2010 Ford F-350 6.4L Power Stroke Cracked Pistons at the Fuel Bowl Lip?
The 2008-2010 6.4L Power Stroke in the F-350 uses a piston with a re-entrant combustion bowl whose lip is a known stress riser. Under the high cylinder pressures the twin-sequential-turbo 6.4L makes, and especially on tuned trucks or trucks that see repeated in-cylinder post-inje… Repairs typically run $8,000-$20,000. Severity: high.
What is the 2008-2010 Ford F-350 6.4L Power Stroke Radiator Plastic Tank Cracking and Repeat Failures?
The 2008-2010 F-350 with the 6.4L Power Stroke uses a plastic-tank/aluminum-core radiator that has a well-documented pattern of splitting where the core is crimped into the tank, and of the tanks themselves cracking. The upper radiator support is thin enough to let the core flex… Repairs typically run $700-$1,800. Severity: high.
What is the 1999-2010 Ford F-350 Exhaust Manifold Bolt Breakage?
The exhaust manifold bolts on the 6.0L and 7.3L Power Stroke diesel engines break due to thermal cycling, causing exhaust leaks with a ticking noise especially on cold starts. Broken bolts are very difficult to extract. Repairs typically run $300-$1,200. Severity: medium.
What is the 2008-2010 Ford F-350 6.4L Power Stroke Fuel Dilution of Engine Oil During DPF Regeneration?
To regenerate the diesel particulate filter, the 2008-2010 6.4L Power Stroke injects fuel late in the exhaust stroke through the main injectors rather than using a downstream dosing injector. A share of that fuel washes down the cylinder walls and ends up in the crankcase. Owners… Repairs typically run $150-$2,500. Severity: medium.
What is the 1999-2016 Ford F-350 Dual-Rear-Wheel Rear Axle Bearing and Seal Failure on F-350 DRW (Dana 80 Full-Float)?
F-350 dually trucks run a full-floating Dana 80 rear axle whose hubs carry adjustable tapered inner and outer bearings with a seal riding on the innermost part of the spindle. Unlike a sealed unit bearing, this design is a maintenance item, and the loads a DRW F-350 carries - a p… Repairs typically run $300-$1,200. Severity: medium.
What is the 1999-2016 Ford F-350 Cab Corner, Rocker Panel and Rear Wheel Arch Rust-Through?
The 1999-2016 Super Duty cab has a double-wall rocker and cab-corner structure that traps water and road debris and rots from the inside out. On the F-350 the pattern is worse than on lighter trucks for two structural reasons: dual rear wheels throw far more salt spray and grit u… Repairs typically run $800-$4,000. Severity: medium.
What is the 2005-2010 Ford F-350 Frame-Mounted Fuel Pump Driver Module Corrosion on Gas Super Duty?
Gasoline F-350s of this era (5.4L Triton V8 and 6.8L Triton V10) use a Fuel Pump Driver Module bolted directly to the steel frame rail behind the rear axle, where it takes the full spray of road salt and water. The aluminum module against the steel frame sets up galvanic corrosio… Repairs typically run $200-$700. Severity: medium.
