Full torque is available at any time on the 4th
generation Haldex clutch because the pressure is
not dependent on the difference in the speeds of
rotation. This is used for instance to activate the
Haldex clutch for better traction when moving off.
On the 4th generation Haldex clutch, the preload
function which applied 80 Nm to the plates in the
3rd generation is no longer required.
On request from the control unit and at engine
speeds above 400 rpm, the electric feed pump runs
and maintains the storage pressure at about 30
bar.
A pressure reducing valve acts as a control valve,
allowing the all-wheel drive control unit to control
the pressure with much greater precision. The
all-wheel drive control unit monitors the position and function of the control valve. The control valve
distributes the pressure, depending on the
requirements, across its three outlet openings
(storage pressure, working pressure, return).
From the storage pressure (30 bar) and depending
on the requirements, the control valve regulates a
working pressure of 0 - 17 bar, which is applied to
the ring piston. At 17 bar working pressure, the
maximum torque of 1000 Nm is transferred to the
rear wheels. The all-wheel drive control unit
ensures the best possible performance under all
driving conditions, for all road conditions and
independent of the speed.

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] .
