The Ford Super Duty (also known as the Ford F-Series Super Duty) is a series of heavy-duty pickup trucks produced by the Ford Motor Company since the 1999 model year. Slotted above the consumer-oriented Ford F-150, the Super Duty trucks are an expansion of the Ford F-Series range, from F-250 to the F-600. The F-250 through F-450 are offered as pickup trucks, while the F-350 through F-600 are offered as chassis cabs.

Rather than adapting the lighter-duty F-150 truck for heavier use, Super Duty trucks have been designed as a dedicated variant of the Ford F-Series. The heavier-duty chassis components allow for heavier payloads and towing capabilities. With a GVWR over 8,500 lb (3,900 kg), Super Duty pickups are Class 2 and 3 trucks, while chassis-cab trucks are offered in Classes 3, 4, 5, and 6. The model line also offers Ford Power Stroke V8 diesel engines as an option.

Ford also offers a medium-duty version of the F-Series (F-650 and F-750), which is sometimes branded as the Super Duty, but is another chassis variant. The Super Duty pickup truck also served as the basis for the Ford Excursion full-sized SUV.

The Super Duty trucks and chassis-cabs are assembled at the Kentucky Truck Plant in Louisville, Kentucky, and at Ohio Assembly in Avon Lake, Ohio. Prior to 2016, medium-duty trucks were assembled in Mexico under the Blue Diamond Truck joint venture with Navistar International.

Here are some of the most frequently reported issues by owners of the 2021 Ford F-350 Super Duty, based on the search results:

Death Wobble: This is a well-known issue affecting many Ford F-350 models, including the 2021 version. The death wobble is a violent shaking of the front end of the vehicle, usually triggered by driving over rough roads or potholes. It can be caused by various factors, such as loose steering components, worn-out suspension parts, or unbalanced tires.
Leaf Spring Issues: The leaf springs in the F-350's suspension system are prone to sagging or breaking, leading to a decrease in ride height and stability. This issue can be more pronounced in heavily loaded trucks or those used for towing.
Steering Wheel Sticking and Locking: Some owners have reported instances where the steering wheel becomes stuck or locked, making it difficult to turn the vehicle. This can be caused by a faulty steering column lock or a problem with the power steering system.
Power Steering Issues: The power steering system in the F-350 can experience issues, such as leaks, which can result in a loss of power steering assist or complete failure.
Rear Wide Axle Issues: The rear wide axle in the F-350 can develop problems, such as excessive wheel hop or vibration, especially during heavy towing. This can be caused by worn-out u-joints, driveshaft issues, or improper tire balancing.
Driveshaft Issues: The driveshaft in the F-350 can experience issues, such as vibration or noise, due to worn-out u-joints, damaged center bearings, or misalignment.
Transmission Lurching Issues: Some owners have reported instances of the transmission lurching or jerking during acceleration or deceleration. This can be caused by a variety of factors, including transmission fluid issues, internal transmission wear, or problems with the torque converter.
Transmission Calibration Issues: The transmission in the F-350 can experience calibration problems, leading to issues such as delayed shifts, harsh shifts, or poor fuel economy.
Unintended Rollaway Issues: There have been reports of the F-350 rolling away unexpectedly, usually due to a problem with the brake shift interlock system. This can be a serious safety issue, potentially leading to accidents or injuries.
Loose Steering: Some owners have reported issues with loose steering, making the vehicle difficult to control, especially at high speeds. This can be caused by a variety of factors, including worn-out steering components, misalignment, or issues with the power steering system.
PTO Pressure Oil Leaks: The PTO (Power Take-Off) system in the F-350 can experience oil leaks, which can lead to a loss of pressure and potential engine damage. This issue is more common in older models but can still affect the 2021 version.
Spark Plug Issues: The spark plugs in the F-350's engine can experience issues, such as fouling or breaking, leading to decreased performance and fuel efficiency.
Turbocharger Issues: The turbocharger in the F-350's engine can experience issues, such as excessive noise or loss of power, due to worn-out components or problems with the intake or exhaust systems.
Engine Block Heater Issues: The engine block heater in the F-350 can experience issues, such as failure to heat the engine or electrical problems, leading to difficulty starting the vehicle in cold weather.
Squeaky Cabin: Some owners have reported issues with squeaking or creaking noises coming from the cabin, usually due to worn-out or loose interior components.
