Did you know… that after December 1968 Citroën modified the suspension units on the “AK” Model, including the 2CV. Following is the service bulletin update:

SUSPENSION UNITS

The front suspension spring AM-431-1 is replaced by the spring AM-431-1a.

Description; Wire Diameter 17.5 mm (.689″)

Free Height 192 mm (7.56″)

Coils circling to the left.

The front tie-rod of the suspension unit AU-434-91 is replaced by the tie-rod AM-434-91.

Length: 625.8 mm (24.638″)

The rear tie-rod of the suspension unit AM-434-91 is replaced by the tie-rod AW-434-92

Length: 607.5 mm (23.917″)

The front rubber stop A-435-76 of the suspension unit is replaced by the stop AK-435-76.

The important thing to remember is:

It is possible to mount the new suspension units or the assembly of all these new parts on earlier models.

The two suspension units of a car should be strictly identical. It is indispensable that the modification must be made simultaneously on the right and left suspension units.

The rubber buffers of the front suspension system should be adjusted to obtain a clearance of 2 mm. (.080″) between the rubber stop and the stop on the suspension arm.

OK, hope this helps and let me know if you have any more questions by asking in the comments box below.

Later,

Denis
