I have a 99 Chevy Silverado 2500 (4wd, 6.0). I bought it with this issue. i believe this year had and EVO steering option but mine does not or it was removed there is no sensor on the steering column or power steering pump.
the issue is i can turn the wheel with 1 finger, i can actually start turning the wheel and let go and it will continue to turn all the way to the stop. I just replaced the steering pump this did not make a difference. Any ideas.
