I recently changed all 6 spheres on my Citroen Xantia 2.0HDI, yr 2000, and the rear suspension is really bouncy as it is full of air when inthe normal driving position. I have followed the Haynes Manual method of priming the system. I also followed Slim method, on an old posting, of priming running the engine when the carin its lowest position and opening regulator 12mm bolt an running for appox 2 mins, then close bolt and take car to its max and top up with LHM fluid if necessary. The suspension also raises to it max and lowers to the minimum ok. I have also take the new rear spheres off and refitted them but noticed there was hardly any fluid inside them as opposed to when I took the old ones off I covered the garage in LHM. any ideas?
