* Vehicles equipped with a tire deflation detection system (DDS) must be inspected for correct operation using the Ford approved diagnostic tool.
To maximize tire performance, inspect the tires for
signs of incorrect inflation and uneven wear which
may indicate a need for balancing, rotation or
suspension alignment. Tires should also be
checked frequently for cuts, stone bruises,
abrasions, blisters and for objects that may have
become embedded in the tread. More frequent
inspections are recommended when rapid or
extreme temperature changes occur or when road
surfaces are rough or occasionally littered with
foreign material.
As a further visible check of tire condition, tread
wear indicators are molded into the bottom of the
tread grooves. When these indicator bands become
visible, new tires must be installed.
Tire Wear Diagnosis
Uneven wear is usually caused by either excessive
camber or excessive toe on tires.
Sometimes incorrect toe settings or worn struts will
cause severe `cupping' or `scalloped' tire wear on
non-driven wheels.
Severely incorrect toe settings will also cause other
unusual wear patterns.
Tire Vibration Diagnosis
A tire vibration diagnostic procedure always begins
with a road test. The road test and customer
interview (if available) will provide much of the
information needed to find the source of a vibration. During the road test, drive the vehicle on a road
that is smooth and free of undulations. If vibration
is apparent, note and record the following:
– the speed at which the vibration occurs.
– what type of vibration occurs in each speed
range.
– mechanical or audible
– how the vibration is affected by changes in the following:
– engine torque
– vehicle speed
– engine speed
– type of vibration - sensitivity: – torque sensitive
– vehicle speed sensitive
– engine speed sensitive
The following explanations help isolate the source
of the vibration.
Torque Sensitive
This means that the condition can be improved or
made worse by accelerating, decelerating,
coasting, maintaining a steady vehicle speed or
applying engine torque.
Vehicle Speed Sensitive
This means that the vibration always occurs at the
same vehicle speed and is not affected by engine
torque, engine speed or the transmission gear
selected.

Engine Speed Sensitive
This means that the vibration occurs at varying
vehicle speeds when a different transmission gear
is selected. It can sometimes be isolated by
increasing or decreasing engine speed with the
transmission in NEUTRAL or by stall testing with
the transmission in gear. If the condition is engine
speed sensitive, the cause is probably not related
to the tires.
If the road test indicates that there is tire whine,
but no shake or vibration, the noise originates with
the contact between the tire and the road surface.A thumping noise usually means that the tire is flat
or has soft spots making a noise as they slap the
roadway. Tire whine can be distinguished from axle
noise. Tire whine remains the same over a range
of speeds.
A complete road test procedure is described in
Section 100-04.
REFER to:
Noise, Vibration and Harshness (NVH)
(100-04 Noise, Vibration and Harshness,
Diagnosis and Testing).

Rear Drive Axle and Differential – System Operation andComponent Description
System Operation
General Information
The powertrain with all-wheel drive consists of the
following main components:
• engine
• transaxle with front axle differential
• transfer box
• halfshafts and driveshafts
• Haldex clutch
• rear axle differential
The Haldex clutch guarantees continuous variable
torque transmission to the rear axle under all
driving conditions. The Haldex clutch reacts
immediately and equally quickly with slow or fast
wheel slip.
A difference in angle of rotation of 90° between the
input and output shafts is required to build up
maximum pressure at the multi-plate clutch or to
transmit maximum torque.
The advantage of vehicles with all-wheel drive is
that they distribute the drive between all four
wheels. They therefore have a higher tractive
power. They feature improved cornering behaviour,
as the grip at all four wheels can be better utilised.
Thus, the wheels contribute to a greater degree
towards cornering stability.
The engine torque is transmitted from the transfer
box to the rear axle via a driveshaft. The driveshaft
is flange-mounted to the input side of the Haldex
clutch.
Driving situations
Pulling away and accelerating
• When pulling away and accelerating, as muchall-wheel drive as necessary must be available
immediately in the short-term. During
acceleration, the electronic system detects slip
at the front axle. This slip is counter-controlled
and thus the propulsive force optimally
distributed to the two axes.
Cornering • A sporty driving style, in particular dynamic
cornering, demands stable cornering behaviour.
The all-wheel system distributes the propulsive
force to all four wheels and by so doing boosts
the high cornering forces so that the vehicle
makes optimum contact with the road surface.
Snow and black ice
• Snow and black ice require particularly high grip. Under these conditions, the Haldex clutch
always distributes the propulsive force to the
axle with the better traction. The all-wheel
system reacts intelligently and quickly to all
driving situations.
Trailer operation
• When driving with a trailer, the trailer weight (support load) is transmitted to the rear axle via
the towbar. This reduces the load on the front
wheels, which means they can slip. The
electronic system detects this difference and
distributes most of the propulsive force to the
rear axle.

Drive
To ensure very fast torque transmission, a higher
voltage is applied to the electric feed pump and
the control valve fully closed before the shaft-driven
pump is brought into operation. As a result, the
maximum pressure is raised above the base
pressure, and a torque of up to 80 Nm applied to
the multi-plate clutch. This achieves significantly
faster pressure build-up than with older systems (second generation). To protect the pump from
overloading, the pressure is restricted to approx.
10 bar by the pressure relief valve. The hydraulic
fluid flows back into the sump via the pressure
accumulator.
