He stuck his arm threw the steering wheel and hut the key. It fired up and wheel went right and truck pump screamed blowing the hoses off. It broke both bones in his forearm sticking the big one threw the skin.
I take it he possibly played with the (centering) valve set-up on the power steering box, that the return hose comes off of.
This valve floats on over-sized bolt holes, mess with it and it'll make the wheel go 1 way or the other INSTANTLY once hydraulic pressure hits the box.
I'll NEVER rebuild my own power steering box, both after a failed attempt with less disastrous results AND because a buddy had a 1975 New Yorker with 400,000 miles randomly YANK the wheel out of his hands a put the car into an Interstate median.
The car had been experiencing a random, self steering problem mere days before, where if you spun the wheel in either direction and let go it would continue to spin the wheels until they locked in the direction it was heading.
Turns out the centering valve was eroded from high miles and failed.
He'd had his warning.
Mark.
