Have a K3500 that has the steering boost system. Driving the interstate, turning slightly right, about 2 to 4 degrees, I feel a bump in the steering. Like when you open the door, there is a raised part of the spring hinge that causes the door to stop in one spot or the next. What I feel is like the space between the two detents on the door spring. Feels a little un-nerving to say the least. Replaced the steering box, and still have the same feeling.
Anybody know anything about the power steering boost assist system?
