Once again, Chevrolet turns out another piece of s#*t! This problem is well documented on the internet. There are TSB "s posted on it . Still, Chevy doesn't give a damn if the steering box falls apart on their vehicles, but you will when you loose your steering on your truck. Chevy is producing a deathtrap, and they don't care!!! God help you if you own one of these piles of crap!
