What is the torque spec for the axle nut on a Ford F150?
The exact torque specification for the F-150’s axle nut varies by year and front‑axle design, but most four‑wheel‑drive F‑150s use about 250 ft-lbs (340 Nm). Always verify the precise value with the factory manual for your specific vehicle.
How the torque spec can vary
Torque requirements depend on the year, engine, drive configuration (2WD vs. 4WD), hub design, and whether the axle uses a traditional nut or a locking/nut with special hardware. Because Ford updated hubs and fasteners across generations, there is no single universal value that covers all F‑150s. Rely on the exact specification listed for your exact model and VIN when performing maintenance.
Typical ranges you may encounter
Note that these ranges reflect common guidance found in service manuals and reputable repair references. Always confirm with the official documentation for your exact truck.
- Most 4x4 F-150 front axle hub nuts: approximately 250 ft-lbs (340 Nm).
- Some 2WD or alternative hub designs: roughly 200–230 ft-lbs (270–310 Nm).
- Special editions or years with unique hub assemblies: can vary outside these ranges; consult the exact manual.
In all cases, use the precise figure listed for your vehicle’s year and configuration and follow any re-torque or seating procedures specified by Ford.
How to locate the exact spec for your vehicle
To avoid guesswork or incorrect torque, locate the exact value in the official documentation for your truck. Ford’s service materials and reputable repair guides provide year- and configuration-specific data.
- Check the owner’s manual or the Specifications section for wheel and axle details.
- Access the Ford Service Information Portal or a licensed repair database (Mitchell1, Alldata, Haynes, Chilton) using your vehicle’s year and VIN.
- Consult a Ford dealership service department with your VIN if you need confirmation or if the exact spec isn’t readily available.
- Verify any special installation steps (two-stage tightening, seating, or recheck intervals) as outlined by Ford for your model year.
Having the correct figure helps ensure proper bearing preload, hub integrity, and long-term reliability.
Practical tips for applying the torque
When performing axle-nut tightening, use a properly rated torque wrench, clean threads, and follow the prescribed sequence or seating procedure from the manual. If the manual calls for a recheck after a mileage interval, be sure to re-torque as recommended and inspect the hub area for any signs of looseness or brake rotor movement.
Summary
Key takeaways: there isn’t a single universal torque value for the Ford F-150 axle nut. Most 4x4 models use about 250 ft-lbs (340 Nm), but exact figures vary by year and hub design. Always verify the precise specification for your exact truck, using official manuals or the dealer, and follow any required seating or recheck procedures to ensure safe, reliable operation.
