GENERAL INFORMATION
Axle assemblies: Check
30A
aLock the slip plates of the lift.
aPosition the vehicle on a lift (see Vehicle: Towing
and lifting) .
aCheck the condition of the following components:
-track rods,
-axial ball joint linkages,
-subframe,
-lower arm rubber bushes,
-lower arm ball joints (see Front driveshaft lower
arm ball joint: Check) ,
-shock absorbers,
-tyres,
aCheck:
-the tyre size (see 35A, Wheels and tyres, Tyres:
Identification, page 35A-7) ,
-the tyre inflation pressure (see 35A, Wheels and
tyres, Tyre pressure: Identification, page 35A-
10) .
aPut the vehicle in the VODM position (vehicle in run-
ning order) (see 30A, General information, Under-
body heights: Adjustment value, page 30A-24) :
-tank full,
-vehicle empty (without luggage, etc.).
aConsult:
-the front axle geometry values (see 30A, General
information, Front axle assembly: Adjustment
values, page 30A-31) ,
-the rear axle geometry values (see 30A, General
information, Rear axle assembly: Adjustment
values, page 30A-38) .
aRefer to the user manual for the geometry tester.
aCheck the geometry using the geometry tester.
aIf there is an inconsistency between the manufactur-
er's values and the measured values:
aAdjust the front axle (see 30A, General informa-
tion, Front axle system: Adjustment, page 30A-
36)

WHEELS AND TYRES
Wheel: Balancing
35A
I - PREREQUISITES FOR WHEEL BALANCING
aWheel balancing is a measurement operation.
Several conditions must be met to achieve a reliable
result in a single operation.
The wheel balancer must be installed in accordance
with the manufacturer's instructions.
It is essential to calibrate the balancer according to
the frequency recommended by the manufacturer.
Do not grease the threaded shaft.
Check the condition of the supports, centring com-
ponents and mountings.
Replace any faulty parts (see manufacturer's in-
structions).
The wheel and the wheel balancer must be clean.
Driver's perception
aIf the wheels are not correctly balanced this causes
the steering wheel and/or the vehicle floor to vibrate.
These vibrations appear between 54 mph (90 km/h)
and 90 mph (150 km/h).
II - BALANCING PREPARATION OPERATION
aAdjust the tyre pressure (see 35A, Wheels and ty-
res, Tyre pressure: Identification, page 35A-10) .
aAlways carry out a road test for a minimum distance
of 1 mile (2 km) before balancing the wheels, in or-
der to remove any flat spots on the tread caused by
the vehicle being immobilised.
aActions to be carried out immediately after the test
drive:
-Position the vehicle on a two-post vehicle lift (see
Vehicle: Towing and lifting) ,
-raise the vehicle,
-leave the four wheels hanging free,
-release the parking brake.a
To reproduce the exact vehicle wheel assembly, use
a ring (1) of diameter:
a60 mm
aThere are three types of weight:
105870
Note:
The ring is available from the supplier of the
equipment used.

III - FINAL OPERATION
aRefit the valve mechanism.
aInflate the tyre to the recommended pressure (see
35A, Wheels and tyres, Tyre pressure: Identifica-
tion, page 35A-10) .
aBalance the wheel (see 35A, Wheels and tyres,
Wheel: Balancing, page 35A-4) .
aRefit the wheel in question (see 35A, Wheels and
tyres, Wheel: Removal - Refitting, page 35A-1) . Note:
It is not necessary to drive the vehicle before and
after a new wheel is balanced.

RIGHT-HAND DRIVE
37A
aConnect a vacuum pump to the end of the non-re-
turn valve.
aActivate the vacuum pump to obtain a vacuum of
500 mbar.
aCheck that the vacuum pressure does not drop. If it
does, the non-return valve is pierced; replace the
valve (see 37A, Mechanical component controls,
Brake servo non-return valve: Removal - Refit-
ting, page 37A-11) .
aRefit the non-return valve pipe on the intake distribu-
tor.V - CHECKING THE VACUUM PUMP
aConnect the external vacuum pump to the engine
vacuum pump.
aStart the engine.
aCheck the following values:
-550 mbar in 5 seconds for an engine speed of 700
rpm,
-700 mbar in 3 seconds and 900 mbar in 5 sec-
onds for an engine speed of 4050 rpm.
aReplace the vacuum pump if the values are different
(see 37A, Mechanical component controls, Vacu-
um pump: Removal - Refitting, page 37A-25) .
aRefit the non-return valve pipe onto the vacuum
pump.
VI - FINAL OPERATION.
aRefit:
-the front right-hand wheel arch liner (see Front
wheel arch liner: Removal - Refitting) (MR 412,
55A, Exterior protection),
-the front right-hand wheel (see 35A, Wheels and
tyres, Wheel: Removal - Refitting, page 35A-1) .
