So--just how do you check fluid levels, internal leaks and dampening force on a ESCO strut with internal dampeners???  I know how to service the strut by compressing it until the fluid runs out and then airing it up to about 300psi, and that was done about 18 mos ago.  So it seems to me if the strut does not collapse and there are no visible leaks (other than the normal engine oil residue after every extended flight) then it is reasonable to assume all is ok with the innards--is there is more to the story, well please enlighten me.

The most basic things to check are fluid level, internal leaks, and damping force.
