Summary Verdict
The 2002 Ford F750 demonstrates good overall reliability, especially when equipped with the robust Caterpillar or Cummins diesel engines. The primary areas requiring attention are typically related to the powertrain, particularly specific transmission components like torque converters and valve bodies in automatics, and clutch wear in manuals. Electrical system issues, often stemming from corrosion in wiring harnesses, are also noted. Suspension components, while built for heavy loads, can experience wear and tear such as leaf spring issues. Regular preventative maintenance and prompt attention to any emerging symptoms are key to maximizing the lifespan and operational efficiency of these workhorses.
