2011 FORD KUGA DRIVESHAFT

General overview
Haldex clutches of the 3rd and 4th generations are
used in the Ford Kuga.
The development of the third generation Haldex
clutch represents a big step forward in modern
all-wheel technology. The Haldex clutch is
electro-hydraulically controlled. Additional
information is taken into consideration during
control tasks via the all-wheel drive control unit.
Slip alone is no longer decisive for the distribution
of the propulsive forces; the vehicle's driving
dynamics are also taken into consideration. The
control unit accesses the driving-related data via
the data bus. With this data, the control unit has
all the essential information about speed, cornering,
coasting or traction operation, and can optimally
react to every driving situation.
Compared with the previous generation, the 4th
generation Haldex clutches operate with higher
pressure and achieve shorter response times when
distributing the drive forces.
Advantages of the Haldex clutch:
• Permanent all-wheel drive withelectronically-controlled multi-plate clutch
• Fast response
• No straining when parking and manoeuvring
• Compatible with different tyres (e.g. emergency spare wheel)
• Fully combinable with driving dynamic control systems
The driveshaft is connected to the input shaft of
the Haldex clutch. Within the Haldex clutch, the
input shaft is separated from the output shaft to
the rear axle differential by means of a multi-plate
clutch. Torque is only transmitted to the rear axle
differential when the plate assembly of the Haldex
clutch is closed.
The multi-plate clutch is electro-hydraulically
controlled via the all-wheel drive control unit. For
ecological driving, the torque to the rear axle is reduced to a minimum up to a throttle position of
approx. 50%. A prerequisite for this is that there is
no difference in speed in the Haldex clutch between
the input and output shafts.

Within the Haldex clutch is a plate assembly and
a so-called ring piston pump with a pump plunger
and a working piston.
Fluid supply is started if there is a speed difference
between the input and output shafts.
This fluid pressure is transmitted to the working
piston and in this way the plate assembly is
compressed.

Front Drive Halfshafts
Inspection and Verification
NOTE:New front wheel drive halfshafts should not
be installed unless disassembly and inspection
reveals unusual wear.
1. Inspect front wheel driveshaft joint boots for evidence of cracks, tears or splits.
NOTE: While inspecting the front wheel driveshaft
CV joint boots, watch for indentations (dimples) in
the boot convolutions. If an indentation is observed,
it must be removed.
2. Inspect the underbody for any indication of grease splatter in the vicinity of the front wheel
driveshaft CV joint boots outboard and inboard
locations, which is an indication of front wheel
driveshaft CV joint boot and/or front wheel
driveshaft CV joint boot clamp damage. 3. Inspect for inboard CV joint stub shaft pilot
bearing housing seal leakage at the front wheel
driveshaft CV joint.
4. Make sure front axle wheel hub retainer is the correct prevailing torque type.
5. The silicone front wheel driveshaft CV joint boot will sweat during operation, causing a light film
of grease to show on the outside of the front
wheel driveshaft CV joint boot. This condition
is normal.
NOTE: Halfshafts are not balanced and do not
contribute to rotational vibration.
6. If the concerns remain after the inspection, determine the symptoms and go to the Symptom
Chart. For additional Noise, Vibration and
Harshness (NVH). REFER to Section 100-04
[Noise, Vibration and Harshness] .

NOTE: From the start of series production, the
transfer box will be subject to a "Black Box Phase"
and will therefore not be repaired.
To realise the all-wheel drive, a transfer box has
been flange-mounted to the manual transaxle. The
transfer box is designed as an angular gear to
transfer the torque from the transaxle to the rear
axle. The hollow shaft of the transfer box is inserted
in a tooth on the gear case. From the hollow shaft,
torque is transferred to the driveshaft through the
output shaft/output flange via crown gear and
differential pinion gear.
