Axles, Suspension, Steering -> Axle Geometry for Your Citroen C3 SUV First Generation (2002-2009)

AXLE GEOMETRY  
Conditions for checking and adjusting  
Tyres inflated to correct pressures.  
Vehicle at reference height.  
Steering rack locked at mid point (See corresponding operation).

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

Measuring front height  
Measuring rear height  
[1] Gauge for measuring the wheel radius, 4 bolts, tool 8006-T  
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 – L1  
Measure the radius of the rear wheel R2 - Calculate dimension H2 = R2 + L2

(*) = CRD : Difficult road conditions.  
Definition for a type of vehicle whose axles and suspensions are adapted 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.
