CAUTION: Do not allow grease to contaminate the wheel stud threads and wheel nut to wheel mating surface, as this
may cause the nuts to loosen.
• NOTE: When installing the wheel, smear a thin layer of grease onto the hub mounting face and spigot; and wheel
mounting face and spigot hole, to prev ent the wheel corroding on to the hub.
Locking Wheel Nuts

Locking wheel nuts are fitted as standard to UK vehicles.

Op
era
tion
Th
e
system selects the soft or
firm damper setting according to the current ro ad and driving conditions, to optimise vehicle
ride and handling.
With the vehicle stationary, the dampers are in the firm setting, but will normally switch to the soft setting when the vehicle
exceeds 8 km/h (5 mile/h); all dampers are switched simultaneously.
Sudden movement of the vehicle body, in response to road inputs, is detected by the vertical accelerometers, and the ADCM
switches the dampers to the firm setting to give improved damping of the resultant oscillations.
When cornering forces are detected by th e lateral accelerometer, the ADCM switches the dampers to the firm setting to
reduce the roll rate an d improve wheel control.
After the event has passed, the dampers revert to the soft setting.
When the footbrake is applied, the ADCM re ceives a signal and calculates the rate of vehicle deceleration. If the deceleration
rate is greater than a certain threshold, the dampers are switched to the firm setting to reduce the pitch rate and improve
wheel control.
If a system failure occurs, the ADCM grounds the output line to the instrument cluster message center, which displays a
text warning SUSPENSION FAULT and illuminates the amber warning lamp. Under fault conditions the system always fails to
the firm setting, so that the vehicle will be safe to drive un der all road and driving conditions.

Two tie rods are fitted between top rear of the final dr ive casing and the front of the wide mounting bracket.

Parts List
Description
The
type 14 HU final drive assembly is a hypoid unit with th
e pinion arranged on the cross-car centerline. The driveshaft
coupling utilizes a cassette type pinion oil seal, which is an in tegral part of the pinion flange. This type of seal cannot be
separated from the pinion fl ange and therefore may only be renewed as a complete seal / flange assembly
The axle shafts are driven by the output flanges which rotate on sealed bearings , these assemblies being retained in the
final drive unit by circlips.

WA
RNING:
BRAKE DUST, IF INHALED CAN DAMAGE YOUR HEALTH. ALWAYS REMOVE BRAKE DUST USING A VACUUM BRUSH. DO NOT USE A COMPRESSED-AIR LINE TO DISPERSE BRAKE DUST
INTO THE ATMOSPHERE.
CA
UTION:
Replacement of nuts and bolts: Various thread-locking devices are used on nuts and bolts
throughout the vehicle. These devices restrict the number of times a nut or bolt can be used. See
section <<100-00>> for information.
CA
UTION:
The Brembo caliper is aligned to the brake disc when it is first installed to the vehicle, therefore,
care must be taken not to disturb this alignment. When removing the caliper; remove the bolts
that secure the anchor bracket to the vertical link only. DO NOT loosen any other caliper bolts.
Raise front of vehicle and support on stands. Refer to section <<100-02>>.
2. Remove wheel. Refer to section <<74.20.05>>.
