Ford 2013 F-650 Owner's Manual page 262

Note for aluminum wheels: Clean each wheel locator pad on the hub
from all dirt, rust and foreign material prior to re-installing rear
aluminum hub-piloted wheels. Apply a light coat of chassis grease,
never-seize or disc brake corrosion control grease, only to the wheel
locator pad.
3. Run the nuts on the studs until they contact the wheel(s). Rotate the
wheel assembly a half-turn to permit the parts to seat.
4. Draw-up the nuts alternately following the crisscross sequence
illustrated under the following wheel tightening sequence illustrations.
Do not fully tighten the nuts. This allows uniform seating of the nuts and
makes sure even face-to-face contact of the wheel and hub.
5. Continue tightening the nuts to the torque specifications in the torque
chart using the same crisscross sequence shown.
6. After operating the vehicle approximately 50 miles (80 kilometers),
check the nuts for tightness. Some natural seating of parts may be
encountered and the torque on the nuts can drop. Retighten all nuts to
specifications.
Once a week, inspect and retighten the wheel stud nuts.
