L1
The dimension«L1» for checking front height is between the level of
the front subframe «b» and the wheel axis «a».
This method eliminates all the variations in measurement due to :
Different wheel fiittings.
Vehicle loading.
Wear or incorrect inflation of tyres.
(Measuring from the wheel axis : tool 8006-T)
AXLE GEOMETRY
General adjustment conditions
Rear height Front height
NOTE : After each movement of the vehicle body, and before each mea-
surement :
- Move the vehicle slightly forwards and backwards, by turning the road
wheel by hand.- Check the tyre pressures.
- Release the handbrake.
- Place the manual height control in the «NORMAL» position.
- Engine running.
L2
The dimension«L2»for checking rear height is between the measuring
zone «b» and the wheel axis «a».
H1 = R1 - L1
H1 = Front height(± 6 mm).
R1 =Wheel radius(mm).
L1 = Theoretical dimension between the level of the front subframe and
the wheel axis.H2 = R2 + L2
H2 = Rear height (± 6 mm).
R2 = Wheel radius(mm).
L2 = Theoretical dimension between the measuring zone on the cross-
member support and the wheel axis.
