I managed to get front oleo apart, not sure what the "grease" is but it is not grease, it is clear and almost like half cured silicon sealant.
I cleaned it out, light lube with blue grease.
The main issue is the spring, virtually nil compression and only about 1mm if that gap between coils.
Surely they can fit a decent spring that is fit for purpose.
Will have to see what I can source to address that problem, oh and a new seal as I could not get it to reseat.
