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)

I - MEASURING POINT
Radius under load:
-R1: Distance between the ground and the front wheel
shaft.
-R2: Distance between the ground and the rear wheel
shaft.
1 - Front height (W1): (W1) : Height between the ground and the side mem-
ber (the measuring point is located 23 mm from point B
of the yoke)
2 - Rear height (W2)

GENERAL INFORMATION
Underbody heights: Adjustment value

(W2) : Height between the ground and the bolt shaft of
the rear axle bearing
II - MEASURING METHODS
Measure the heights:
-R1,
-R2,
-W1 right-hand and left-hand,
-W2 right-hand and left-hand.
Special cases:
Fit a bar across the lift.1 - Plate higher than the lift:
Measure the heights (1) , (2) , (3) .
Example: (1) = 6 cm, (2) = 8 cm, (3) = 10 cm.
Calculate the height Wx:
Wx = height (1) + height (3) - height (2) ,
Wx = 8 cm.
2 - Plate lower than the lift:
Measure the heights (1) , (2) , (3) .
Example: (1) = 8 cm, (2) = 10 cm, (3) = 4 cm.
Calculate the height Wx:
Wx = height (1) + height (2) + height (3) ,
Wx = 22 cm.
III - VEHICLE IN RUNNING ORDER POSITION
VODM (Vehicle in working order) position:
-Tank full,
-Empty vehicle (without luggage, etc.).
139112
Note:
For the measurement of W1 and W2, take into
account the height differences between the plates
and the final drive.
Note:
The value of Wx to be entered into the geometry
bench is the average of the W1 heights, right-hand
and left-hand and of the W2 heights, right-hand and
left-hand.
Note:
If the measuring points are located in empty space
(betw een the rails of the lift), use a bar.
