If this is the lift I am thinking about, the steering valve on the power steering cylinder is out of adjustment. Take the drag link out that goes to the steer axle and up in the valve where the drag link goes, there is an allen head bolt. Screw the allen bolt in to get the slack out to where the bolt fits flush against the ball stud. Screw the drag link back in. If you get it too tight it will be hard to steer.
