The rear suspension has become very soft on my 1993 405 GR 4x4.
By "soft" it behaves as expected when stationary, but when moving the
rear end bounces far more than normal.
To complicate matters, I have been led to believe that the rear axle may
be a Citroen unit on this model of car.
Is it possible that one of the units is leaking? (I have recently had to
add fluid to the resevoir and the level is now correct) If so, can air
get into the unit and cause this effect?
Are there bleed valves?
All suggestions appreciated. I have also cross posted this to the
Citroen group in case it is a Citroen rear axle.
