2006 Ford F-150 Axle Nut Torque Spec

OEM-referenced axle nut torque, socket size, and thread specs for the 2 axle and hub nut fasteners on the 2006 Ford F-150 — including the Front Hub Spindle Retainer Nut (2WD — Large Outer Spindle Nut) (torques to 295-296 ft-lbs, 1-3/4 in or specialized spindle nut socket socket, Large SAE spindle thread thread). The axle nut retains the CV axle in the hub and on many designs sets the wheel bearing preload, so the exact torque matters. Full bolt specs for the rest of the vehicle are linked below.

Front Axle / Hub Nut torque — 2006 Ford F-150

On the 2006 Ford F-150, the front axle / hub nut specs are: Front Hub Spindle Retainer Nut (2WD — Large Outer Spindle Nut) (torques to 295-296 ft-lbs, 1-3/4 in or specialized spindle nut socket socket, Large SAE spindle thread thread); Front CV Axle / Halfshaft Hub Retainer Nut (4WD center nut) (torques to 20 ft-lbs (27 Nm), 36 mm socket, M36 or proprietary thread). Axle nuts are safety-critical — staked and crimp-collar nuts are single-use on many models, so fit a new nut where the manufacturer requires it and verify the value against your factory service manual before reassembly.

How to torque the F-150 axle nut correctly

Remove the cotter pin or unstake the old nut with a punch before loosening — never zip a staked nut out through the stake. Break the nut loose with the wheel on the ground (or have a helper hold the brakes) using a breaker bar. On reassembly, seat the CV axle fully, thread the new nut by hand, and bring it to the final spec with a calibrated torque wrench — an impact gun overshoots the spec and can damage the wheel bearing. Stake the collar into the spindle groove (or fit a new cotter pin / cage) once torqued. An under-torqued axle nut lets the bearing run loose and fail; an over-torqued one destroys the bearing preload.
