Summary Verdict
The 2001 Ford F750, particularly with its Caterpillar and Cummins diesel engine options, is generally considered a reliable workhorse. The most common significant issues tend to be related to fuel system components (injectors, pumps) and turbochargers on the engines, and torque converters or solenoids in the automatic transmissions. Manual transmissions can experience wear on synchronizers. Suspension components like leaf springs are subject to heavy use and potential breakage. Electrical systems can suffer from corrosion over time, and body rust is a concern in certain climates. Overall, with proper maintenance and addressing issues promptly, the F750 can provide dependable service for demanding applications.
