General conditions required for adjustment
- Check the tyre pressures.
- Parking brake released.
- Manually set the height to the «NORMAL DRIVING» position.
- Engine running.
Note : After each body movement, and before each measurement :
Move the vehicle backwards and forwards slightly by pushing the
road wheel by hand.
Front height
H1 = R1 – L1
Rear height
H2 = R2 + L2
H1 : Front height (+7. – 10 mm)
R1 : Wheel radius in mm.
H2 : Rear height (+7. – 10 mm)
R2 : Wheel radius in mm.
L1 : Theoretical dimension between
the front subframe contact surface
and the wheel axis
L2 : heoretical dimension between
the bearing surface of the bodyshell
and the wheel axis
Example : front height
- Measure dimension R1 (centre of the wheel) on the vehicle.
- Subtract L1 from R1 (See the table on page 223) and calculate H1.
- Measure H1 on the vehicle.
- The measured dimension H1 should be the same as the calculated
dimension H1 (+ 7. – 10 mm)
- Adjust the heights if necessary.
