2017 FORD F750 wheel bolt 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.
Operating the steering system excessively
at an elevated engine RPM (>1200 rpm)
for more than 2 minutes can result in
steering system damage from overheating.
Move the steering wheel to the full left
position then full right position at idle
speed, or stop using the system for 2
minutes to allow the system to cool down.
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.

TECHNICAL SPECIFICATIONS
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.
