H1 = Measurement between the measuring zone underneath the front
subframe and the ground.
R1 = Front wheel radius under load.
L1 =Distance between the wheel axis and the measuring zone underneath
the front subframe.H2 = R2 + L2
H2 = Measurement between the measuring zone underneath the rear sill
and the ground.
R2 =Rear wheel radius under load.

Z1= Measuring zone underneath the front subframe.Z2= Measuring zone underneath the rear sill.
Measure the radius of the front wheel R1 - Calculate dimension H1 = R1–L1Measure the radius of the rear wheel R2 - Calculate dimension H2 = R2+ 2

(*) = CRD: Difficult road conditions: definition for a type of vehicle with axles and suspension designed for driving on rough roads.
Compress the suspension to obtain the calculated values.
The height difference between the two axle dimensions should be less than 10 mm.

SPECIAL FEATURES: STEERING
Preliminary operation.
Raise and support the vehicle on a two-column lift.
Remove (on RH side):
- The clip (1).
- The clip (2).
Detach the steering rack protection gaiter.
Setting.
Move the steering to full left hand lock.
Measure the dimension X.
Move the steering to full right hand lock.
Measure the dimension Y.
Calculate the dimension: L = (Y - X) : 2.
Position the steering rack to the dimension “L”
(mid-point of the steering rack).
Refit:
- The protection gaiter.
- The clip (1)
(new)and the clip (2).
