Summary Verdict

The 2008 Ford F-450 Super Duty is a capable work truck, but owners should be aware of potential issues, particularly with the 6.4L Power Stroke diesel engine, which can experience EGR cooler and turbocharger problems. Gas engines, while generally more robust, can suffer from spark plug ejection and camshaft phaser issues. Transmission reliability is generally good, especially the manual, though the automatic can have torque converter or solenoid issues. 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 exterior corrosion are also points to consider. Regular maintenance and prompt attention to any unusual symptoms are crucial for maintaining the longevity and reliability of this heavy-duty vehicle.
