What is the 2011-2019 Ford F-350 6.7L Power Stroke Turbocharger Bearing and Actuator Failure?
The 6.7L Power Stroke turbocharger's variable geometry vanes stick from soot buildup, and the turbo actuator motor fails, causing limp mode and reduced power. Extended idle time and short-trip driving accelerate soot accumulation on the VGT vanes. Repairs typically run $500-$3,500. Severity: high.
What is the 2011-2016 Ford F-350 6.7L Power Stroke EGR Cooler Cracking and Coolant Loss?
The 2011-2016 F-350's 6.7L Power Stroke uses an EGR cooler that is subjected to thermal cycling between roughly 1,200 F exhaust gas and 200 F coolant. Repeated expansion and contraction fatigues the cooler core and it cracks internally, letting coolant into the exhaust stream. Ow… Repairs typically run $1,500-$3,500. Severity: high.
What is the 2005-2025 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 2011-2016 Ford F-350 6.2L Boss V8 Cam Phaser Rattle and Exhaust Manifold Studs?
The 6.2L gas V8 in the F-350 develops cam phaser rattle on startup as the phaser locking pins wear. Additionally, the exhaust manifold studs break due to thermal cycling, causing an exhaust leak. Both issues worsen progressively. Repairs typically run $500-$2,500. Severity: medium.

F-350 dually trucks run a full-floating rear axle (a Dana 80 on most, a Sterling 10.5 on some gas duallies) 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 mainten… Repairs typically run $300-$1,200. Severity: medium.

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.
