Yeah, they are supposed to be new, I was also suprised when I saw the corrosion. I will go and ask for another one. These two that are the same are for the rear corners of the car. There are some stamped codes, the two same ones have AX-041 stamped on them, and a date, and thats about it.andmcit wrote:I'm surprised there's corrosion on the one to the left of the picture
- are these supposed to be new?
This particular sphere is different to the other two in the fact that the throat
where the sphere threads is totally open and doesn't have an inserted 'jet'
that is effectively the damper for the flow of fluid into the sphere and
against the nitrogen gas pocket inside. This particular design is never fitted
to the corners of the car, only in the position of the hydractive centre sphere
at either axle and the main gearbox mounted accumulator/regulator sphere.
This also means the other two which appear to match are corner spheres.
I cannot tell from the picture just by looking at them if they're the exact type
for hydractive mind although this will be a smaller size diameter to non
hydractive! Have you managed to check the feed pipe on your actual car
to confirm which suspension system it uses?
On the second two spheres, are there any stamped figures on the silver disc
where the 'jet' into the sphere is - Citroen as standard practice put the
measurement on this end disc astride the opening as a 0.7, 1.1 etc
measurement.
Additional markings are sometimes stamped on the outer crown of the
sphere just off the "nipple" top which indicate the pressure in "bar"
that's inside from new. If the sphere is an aftermarket one there's a
good possibility of black dot printed serial numbers or even labels on
the sphere to allow specific version recognition - otherwise the spheres
will tend to all look the same at a casual glance.

The unique one is indeed for the centre sphere, and is marked AX-003.
I didn't get the old spheres off yet, because they are very dirty and stuck and corroded possobly, so I'm using a lot of WD-40 to try and get it off. I'll post a picture as soon as I get it of.
I don't think it is a hydractive, and if it isn't then I suppose I would just need one more corroded one
to change all four, right?Remeber, I need to change all four spheres in the back.
