In desperation I removed the sphere which released a small amount of LHM+ fluid but nothing to suggest there was any pressure left in the system BUT shortly after I thought I saw the nut drop down to the unit, it had released itself with hardly any effort from a solid grip like some sort of gravity Ninja

So somewhere / somehow / something was affected which altered the struts attitude ... vacumn

No corrosion on strut

Cheers for the gaiter CitroJim
Just got the original fault to replace now and buy some more LHM+ and we should be back on the road .....
