AXLE GEOMETRY

General conditions required for adjustment

NOTE : After each body movement, and before each measurement :

- Check the tyre pressures.

- Move the vehicle backwards and forwards slightly by pushing the road

wheel by hand.

- Parking brake released.

- Manually set the height to the «NORMAL DRIVING» position.

- Engine running

Front height

H1 = R1 - L1

Rear height

H2 = R2 - L2

H1 = Rear height

H1 = Front height

All Types (+ 7 - 10 mm)

SC CAR (± 3.5 mm)

All Types (+ 7 - 10 mm)

SC CAR (± 3.5 mm)

R2 = Wheel radius in mm.

L2 = Theoretical dimension between

the bearing surface of the bodyshell

and the wheel axis.

R1 = Wheel radius in mm.

L1 = Theoretical dimension between

the front subframe contact surface 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 214) 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.
