Have just changed my rear spheres on '97 TD SX AT 90,000 MILES.
Have gone from really hard rear suspension to extremly bouncy,only good thing is now hydraulic pressure light goes out in 2 secs instead of 15 secs,believe this was down to internally ruptured sphere.
Think i liked hard ride better than rear wallow tho,any ideas out there? {new spheres were recon. units -sigh)[8D]
XANTIA REAR SUSPENSION CAUSING NAUSEA
Moderator: RichardW
Don't worry, some air is left trapped in suspension cylinders, so the damping is too low now, causing effect like in the car with conventional suspension with worn dampers. Air will drift out through the return lines in several days. Also, try some "citrobics", it will quicken this process.
Other possibility is wrong spheres, of course. But, before checking them at the garage, wait a week or so.

Don't lose any sleep over it as it's a problem that is quite solveable.
Where I live, new spheres are a rareity and the usual is to get them regassed (or recond as some would like to call them.) The problem often is that mechanics out here, even those involved in regassing spheres have less knowledge about how spheres work than most people on this board so as a result we get some monumental messes caused by them trying theories discussed over several pots of the amber fluid. A typical example was a few years back when due to business commitments I used a specialist to do my service. After a while we noticed the car was extremely instable & rode shockingly and my wife usually always drove the car; it was about the time I decided to hang up the tools full time so went back to doing my own work. First thing was I sent all the spheres to Pleiades and received a call asking how many cars I owned & why I hadn't sent just a set off one car. It seems that the spheres off my CX were from CX Safari, BX, GS....you name it I had it!! everything but CX Sedan spheres. When I contacted the "specialist" & asked how this had happened his response was they all were charged to the same pressure so it made no difference! [:p]Locating a set of original spec spheres & having Pleiades regas them solved the problem.
I recently had an action replay with a BX 16V we bought to convert to a race car. I had heard from someone previously that this car was a shocking handler prior to being written off after an underbonnet fire, so I tried the front spheres on my 16V & posted after this test drive what the results were.
Here is the link to that posting that gives a good demonstration of the effects of having wrong spheres and what to look for to rectify the problem.

It could be that you have air in the system, but I feel most likely that the cause could also end up being the fitting of incorrect spheres as I have reason to believe that some of your specialists over there show similar traits to some of ours.[:p][:p]

Hmm...there's going to be something in the order of 700 to 800 psi of hydraulic pressure in the rear circuit during normal operation, so as far as I can see, the air that gets in during a sphere change should be compressed to virtualy nothing when the system is pressurised, so I don't think air is going to be your problem.

Well, who knows...
I noticed such a behavior of my BX last time I regassed rear spheres. Rear end was too underdamped at first. It was most noticeable on the backside of a sleeping policeman in the neighborhood, where rear end crashed down like in Volkswagen. I thought I screwed up, because I fitted spheres from GS, unsatisfied with harsh ride in the car (according to data on www.bx.citroen.org, problem was in wrong rear spheres). But, after several days, this problem disappeared and now I'm really enjoying the ride.
Since the pressure in rear spheres didn't change in a few days, neither the outside temperature, I think explanation could be air bubbles in LHM, because mixture of LHM and air bubbles has lower viscosity, affecting the damping in a similar way like in worn conventional dampers.

[?]Suspension bounce did not change over 3 weeks so removed 'new' speres noticed on neck one was marked 44 other had no mark- original were both marked 23 (do not know what this refers to) but managed to get another two 'new' spheres with 23 on each- fitted them and am seeing slight improvement. Think i need to change front two spheres as well for marked improvement[:p]
