Sorry to hear about this. In for pics.

 

I follow directions well and assembled everything as directed. I lifted both my daughters' Foresters as well as my 86 Stang and had zero issues. Having an internal O Ring fail is not, I think, due to any assembly failures on my end.

 

I asked because you specifically mentioned intentionally over-tightening the factory subframe bolts of your S2000. With o-rings, over-tightening and the resulting compression set is one of the common reasons for failure. Your post caused me to look into this and actually has me questioning my own assembly procedure.

 

This is my worst fear of these things.

 

Rob Robinette, recommended spec torque plus 10%, so that's what I did.

 

The O-Ring failure was in the quick connect, which I did not assemble, but attached to the jack pump.

 

Alright, now I understand. Sorry man, that is definitely worrisome.

In your mind, were it possible to weld one additional safety lock (the metal block) in place on each of the Quick Jack frames, do you think that this might have prevented what ultimately happened to you in the case of a hydraulic failure? In other words, the cantilever arms on each side that swing freely as the car is raised would then have had one more hard stop before the car is left to drop all the way to the ground. In your case it sounds like the arms on each side would have already cleared a third (lowest) locking point so that the amount of distance the car could have dropped on the faulty side would have been limited by the additional lock point.

 

any pictures yet?

 

Same happened to me. Was on my way up when one side gave. I have since "bled the system". I almost always stack tires under the car, but didint this time cause I was doing exhust work.

 

Another gotcha I found out. Never drop as low as that picture above. My unit won't raise at all from this stance. It's like the first 1in of lift has zero strength, but rest is fine. I've not done anything to look into this though so maybe not normal.
