2016 FORD F650 wheel torque

STEERING
To help prevent damage to the power
steering system:
•
Never hold the steering wheel at its
furthest turning points (until it stops)
for more than three to five seconds
when the engine is running.
• Do not operate the vehicle with a low
power steering pump fluid level (below
the MIN mark on the reservoir).
• Some noise is normal during operation.
If excessive, check for low power
steering pump fluid level before
seeking service by your dealer.
• Heavy or uneven efforts may be caused
by low power steering fluid. Check for
low power steering pump fluid level
before seeking service by your dealer.
• Do not fill the power steering pump
reservoir above the MAX mark on the
reservoir, as this may result in leaks
from the reservoir.
If the power steering system breaks down
(or if the engine is turned off), you can
steer the vehicle manually, but it takes
more effort.
If the power steering system exhibits heavy
or uneven efforts, check for the following
before seeking service from your dealer:
• An improperly inflated tire.
• Overloading of front suspension.
• Uneven vehicle loading.
• Binding suspension components.
If the power steering system wanders or
pulls, check for:
• An improperly inflated tire.
• Uneven vehicle loading.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components. •
Improper vehicle alignment.
• High crosswinds.
If any steering components are serviced or
replaced, install new fasteners (many are
coated with thread adhesive or have
prevailing torque features which may not
be re-used). Never re-use a bolt or nut.
Torque fasteners to specifications.
A high crown in the road or high crosswinds
may also make the steering seem to
wander or pull.

Towing Vehicles Equipped with a
Driver-controlled Differential Lock
Note:
If you have to tow your vehicle to a
service facility with the drive axle wheels on
the ground, it is necessary to remove the
axle shafts before towing your vehicle.
Removing Axle Shafts before Towing
1. Shift the main differential to the unlocked (disengaged) position; the
differential lock light turns off.
2. Remove the cap screws and washers or stud nuts and washers from flanges
of both axle shafts.
3. Loosen the tapered dowels in the flanges of both axle shafts by holding
a 1 ½-inch diameter brass drift or
hammer against the axle shaft center
and hitting it with a five or six pound
hammer.
Note: Do not use a chisel or wedge to
loosen the axle shafts and dowels. Use of
a chisel or wedge can damage the hub, axle
shafts and oil seals.
4. Remove the tapered dowels and both axle shafts from the axle assembly.
5. Assemble a cover over openings of both wheel ends to prevent loss of
lubricant and keep dirt away from the
wheel bearing cavities.
Note: One of the axle shafts has two sets
of splines. One set to engage with the
differential side gear and one set to engage
with the shift collar for the differential lock.
It may be necessary to rotate the shaft
slightly to align the gear spline teeth with
the shift collar teeth in order to remove the
axle shaft.
Installing the Axle Shafts
1. Remove the covers from the wheel ends.
2. Shift the differential lock to the unlocked (disengaged) position. 3. Install the axle shafts as outlined in
Steps 4 through 10.
4. Place the gaskets on the wheel hub studs.
5. Push the right-hand axle shaft and gasket into the wheel end and housing
until the shaft stops against the
differential shift collar.
6. Push down and in on the axle shaft flange and rotate the shaft until the
splines of the shaft and shift collar are
engaged.
7. Push the axle shaft further into the housing until the shaft stops against
the differential side gear.
8. Push down on the axle shaft flange and
rotate the shaft until the splines of the
shaft and side gear engage.
9. Push the axle shaft completely into the
housing until the axle shaft flange and
the gasket are flush against the wheel
hub.
10. Install the left-hand axle shaft and gasket into the wheel end.
11. If tapered dowels are required, install
them at each stud and into the flange
of the axle shaft. Use a punch or drift
and hammer, if needed.
12. Install the fasteners and tighten to correct torque value. See the
Workshop Manual.
FIFTH WHEEL OPERATION WARNINGS
Failure to follow the fifth wheel
manufacturer
’s instructions for
hooking and unhooking as well as
sliding the fifth wheel could result in an
accident, personal injury or death.

2. Loosen each wheel lug nut ½ turn
counterclockwise, but do not remove
them until the wheel is raised off the
ground.
3. Replace the flat tire with the spare tire,
making sure the valve stem is facing
outward on all front and inboard rear
wheels. If you are replacing the
outboard wheel, the valve stem must
be facing inward. Reinstall the lug nuts
until the wheel is snug against the hub.
Do not fully tighten the lug nuts until
the wheel has been lowered.
4. Lower the wheel and fully tighten the lug nuts in the order shown below. See
Technical Specifications (page 249).
5. Unblock the wheels. 8-lug nut torque sequence.
10-lug nut torque sequence.

Wheel Lug Nut Torque Specifications
WARNING
When a wheel is installed, always remove any corrosion, dirt or foreign materials
present on the mounting surfaces of the wheel or the surface of the wheel hub,
brake drum or brake disc that contacts the wheel. Make sure that any fasteners
that attach the rotor to the hub are secured so they do not interfere with the mounting
surfaces of the wheel. Installing wheels without correct metal-to-metal contact at the
wheel mounting surfaces can cause the wheel nuts to loosen and the wheel to come off
while the vehicle is in motion, resulting in loss of control. lb.ft (Nm)

* Torque specifications are for nut and bolt threads free of dirt and rust. Use only Ford
recommended replacement fasteners.
On vehicles equipped with single rear wheels, retighten the lug nuts to the specified torque
at 100 miles (160 kilometers) after any wheel disturbance (such as tire rotation, changing
a flat tire, wheel removal).
On vehicles equipped with dual rear wheels, retighten the lug nuts to the specified torque
at 100 miles (160 kilometers) and again at 500 miles (800 kilometers) of new vehicle
operation and after any wheel disturbance (such as tire rotation, changing a flat tire,
wheel removal).
It is important to follow the proper wheel mounting and lug nut torque procedures. On all two-piece flat wheel nuts,
apply one drop of motor oil
between the flat washer and the
nut. Do not apply motor oil to the
wheel nut threads or the wheel
stud threads.
