According to ARB, this leaking is an installer error, of the o-ring onto the ARB shaft. Basically, if that o-ring twists any when being installed, it'll fail. You have to be extra-special careful in sliding it on, so it doesn't roll any. It was a PIA when I installed my ARB, but then again, it hasn't leaked in over a year and a half, so I guess being careful has it's advantages.

Don't know if this is totally true, though, as I would think the o-ring would virtually un-roll itsself back to its natural state, w/in a few minutes. So this could just be ARB's way of covering their arse... Blame it on an install error....
