Man, I feel for ya bro...... I think we have all been there; but the question is: Why do we keep on going back to wrenching when wrenching can be so dang frustrating.
This reminds me of my brother who had reached the end of his rope working on an old 1970 Subaru. He literally went ape on us;...the poor guy was running around the garage mimicking an angry chimpanzee throwing crap everywhere. I mean he was doing the "eee-eees & ooo-ooohs".

It was the only way he could cope at the moment; a human doesn't have as much emotion to display as an ape.... Man; that sure was funny!
