Nope not in 4x4. I just put new GM pump in today, backing out of my shop... Put in drive ... Go to turn and completely lose power steering until I move. I'm thinking box!!! I wouldn't care so much but I can't back up a trailer at this point. The best I can deceive it is that your trying to turn with a snow plow on and not moving the truck. As soon as you move a inch it comes back.
