What  causes a jack or even an engine crane to stop holding a position and
settle  back down after a while? Is it low fluid or a bad gasket or a
combination  of things? I know that there's an industry standard for how much
one can  drop over an x period of time. But I'm talking about a matter of
minutes  with or without a load on it?



Jacks today are cheap enough that I replaced mine when it started doing  
that. HF used to sell a universal seal kit.
