Not so much "symptoms" as it is how the power steering is on certain A bodies. Gives them a "light" "disconnected" feeling between the steering and the road. The problem is the pump is too strong. Makes the steering floaty feeling. That's how I can best describe it. But it's odd. Makes it more difficult to center and point the car. To cut/carve corners. You feel separated from the front tires. This mod is designed to be a half way point between over the top power steering and terrible in parking lots manual steering. Gives you a lot of that manual feel on the road. While still having the ability of power steering. It's a recommended mod for anyone doing serious corner driving in their car. As far as I understand it. I haven't done it yet, but its on the list.
