STEERING
Hydraulic Power Steering
To help prevent damage to the powersteering system:
•Do not hold the steering wheel at itsfurthest turning points for more thanthree to five seconds when the engineis running.
•Avoid continuously steering back andforth with elevated engine RPM as thismay overheat the system. If trying tofree a stuck vehicle, pause betweenattempts to allow the power steeringsystem to cool or seek assistance.Typical steering and driving maneuversallow the system to cool.
•Do not operate the vehicle if the powersteering pump fluid level is below theMIN mark on the reservoir.
•Some noise is normal during operation.If excessive, check for low powersteering pump fluid level beforeseeking service by your dealer.
•Heavy or uneven efforts may be causedby low power steering fluid. Check forlow power steering pump fluid levelbefore seeking service by your dealer.
•Do not fill the power steering pumpreservoir above the MAX mark on thereservoir, as this may result in leaksfrom the reservoir.
If the power steering system breaks downor if you switch the engine off, you cansteer the vehicle manually, but it takesmore effort.
If you have any steering componentsserviced or replaced, install new fasteners.Many fasteners have coatings with threadadhesive, or have prevailing torquefeatures you cannot reuse. Do not reuse abolt or nut. Torque fasteners tospecifications.
Steering Tips
If the steering wanders or pulls, check for:
•An improperly inflated tire.
•Uneven tire wear.
•Loose or worn suspensioncomponents.
•Loose or worn steering components.
•Improper vehicle alignment.
Note:A high crown in the road or highcrosswinds may also make the steeringseem to wander or pull.

TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications
WARNING: When you install a wheel, always remove any corrosion, dirt or foreignmaterials present on the mounting surfaces of the wheel or the surface of the wheelhub, brake drum or brake disc that contacts the wheel. Make sure to secure any fastenersthat attach the rotor to the hub so they do not interfere with the mounting surfaces ofthe wheel. Installing wheels without correct metal-to-metal contact at the wheelmounting surfaces can cause the wheel nuts to loosen and the wheel to come off whileyour vehicle is in motion, resulting in loss of vehicle control, personal injury or death.

1 Torque specifications are for nut and bolt threads free of dirt and rust. Use only Fordrecommended replacement fasteners.
On vehicles equipped with single rear wheels, retighten the lug nuts to the specified torqueat 100 mi (160 km) 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 torqueat 100 mi (160 km) and again at 500 mi (800 km) of new vehicle operation and afterany 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 oilbetween the flat washer and thenut. Do not apply motor oil to thewheel nut threads or the wheelstud threads.
