Variable Effort Steering (VES) has erratic boost

The issue I'm having is kind of hard to explain. Say for instance I'm driving on the highway and when I slightly turn the wheel, either left or right to change lanes, my steering wheel jerks to that side. It's not bump steer, because this happens on the smoothest of roads, and only happens when I slightly turn the steering wheel left or right to change lanes. My inner and outer tie rods are Moog, and less than a year old. My Idler arm is ac delco and less than a month old. Could the steering box be causing this?

So is there anything I can do besides just getting used to it lol? I can't deal with having stiff steering one day, loose the next. Not to mention feeling like my car is sliding on ice every time I go to take a curve or change lanes. There has to be a solution.
Unplug the four-pin potentiometer connector from the bottom of the steering column near the firewall (engine side). Problem gone forever in my car... just have full assist at all times. Much better than having scary steering through curves.

And you haven't experienced anything bad yet until it happens to you on ice or snow covered off ramp curve!!!

I give GM a 0 out of 10 for using a potentiometer on the steering column instead of an LVDT for this variable effort steering system.
