In what manner are they failing? you used the word "pop"?
I think the failure can only be caused by two things, really: Over-Pressure blowing seals, or over-extension pushing the ram/piston out of the cylinder.
I think over-pressure is unlikely, given the little I know about hydraulic systems. I'm leaning to over-extending. I wonder if it's possible that the arm holding the T/O bearing is off it's fulcrum, and this is allowing the piston to just keep traveling well beyond its design?
I dunno..... I'm making this up, since I've never run into this before.
I guess the third possibility is that you DO, in fact, have multiple bad units. Are you switching brands? Or are you using the same brand over and over? if so: WHAT brand?
