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 steering wanders or pulls, check for:
•an improperly inflated tire
•uneven tire wear
•loose or worn suspension components
•loose or worn steering components
•improper steering alignment
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 inWorkshop Manual.
A high crown in the road or high crosswinds may also make the steering
seem to wander/pull.

On vehicles equipped with dual rear wheels, retighten the wheel 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).

* Torque specifications are for nut and bolt threads free of dirt and
rust. Use only Ford recommended replacement fasteners.
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.
Inspect the wheel pilot hole and
mounting surface prior to
installation. Remove any visible
corrosion or loose particles.
