H1
= From the front suspension arm linkage bolt axis to the ground.R1= Radius of the front wheel when laden.L1= From the centre of the wheel to the front suspension arm linkage
bolt axis.
H1’= From the front jacking point to the ground.L1’= From the front jacking point to the radius of the front wheel when
laden.
H2 = R2 L2
H2
= From the rear axle silentblock face to the ground.R2= Radius of the rear wheel when laden.L2= From the centre of the wheel to the rear axle silentblock face.
AXLE GEOMETRY
Checks at reference height
NOTE:
To make the setting of reference height easier, it is acceptable to take the measurement from the flange of the jacking point.
WARNING: The values shown should only be used as guides. In case of doubt, check the settings at reference height

AXLE GEOMETRY
Compress the suspension to obtain the calculated values.
NOTE:The difference in height between the two sides should be less than 10 mm. Measure the radius of the rear wheel:
R2.
Calculate dimension H2. Measure the radius of the front wheel:R1.
Calculate dimension H1or H1’.
Checks at reference height (the reference height of the vehicle is set as per the table below).
