I've read the article (I think from rovernet.net) regarding repairing/recharging SD1 self levellers, and since I'll soon have a sacrificable pair of vitesse units I fancy giving it a go - even if it's just to find out how they work.
Unfortauntely the article doesn't give anywhere near enough information e.g. why they fail, what seals to replace, where to get spares, where to mount a fill valve, how much oil to put in etc.
Does anyone know if this informtion is available anywhere? If not there's really little point trying.
