So do it!

Do it!

Do it!

(and take some pictures)
The real issue in doing these, which is IMPORTANT, is the material composition of the hydraulic seal.

Within Citroens, as Army may know, older cars used vegetable-based hydraulic oil and they used EPDM-based seals. aka LHS seals

Later cars used mineral-based fluids which required butyl-N or N-buta seals. aka LHM seals.

I am told Viton seals will work in both types, but have no data to back this up.

I someone wanted to send me a leaking strut which I could rebuild for them, I would make a small sticky on it. I'd also need a tiny bit of the fluid to analyse.

BTW in a pinch mineral-based can use Dexron, but not type F ATF, but it's good to replace it afterwrads, it's only good for a couple years.

Hykon Glacial Blue is usually good for several years.
