4 WHEEL DRIVE MODELS
1980 F-350, 1980-82 F-250, 1980-85 F-150 & Bronco & 1984-85 F-250 Exc. w/Dana 501FS Axle
If vehicle is equipped with free running lock-out hubs, refer to ``Front Wheel Drive Section'' for removal and installation procedures. On 1985
Bronco and F-150-250 4 x 4 models built after June 30, 1985, a one piece spindle bearing locknut was used, requiring a revised procedure.
When removing manual hub, use spanner wrench PN P84-171-2 or equivalent. Insert spanner wrench tangs into four slots on nut assembly,
apply inward pressure to unlock bearing nut locking splines and turn counterclockwise to loosen nut.
When installing, thread the new one piece locknut onto spindle with metal stamping inboard., ensuring I. D. key on metal stamping enters spindle
keyway. Insert spanner wrench tangs into four slots on locknut assembly, apply inward pressure to unlock bearing nut locking splines and torque nut to
50-60 ft. lbs. to seat wheel bearings. Back off nut approximately 180 degrees, then torque to 15 ft. lbs.
New spindles have been released with a wider keyway. The one piece locknut can only be used with new spindles. Prior design level lock nuts will
continue to be available for servicing of old spindles.
