Dual Cam setup

So I set up the dual cam last year. the truck rode great. the only issue was some sway during wind gusts, large trucks or line of cars passing and some bouncing from the rear end. I just put new lt tires on the car. The first trip out this year it seems like the trailer is pushing the car to the left or right. it seems to get when when going through a curve. Driving 60-65 expressway is good except the occasional push. No more bouncing and little sway. Driving on the back roads at 40-45 is bad. I feel like im getting pushed all over the place. It was not like this the last year at all. it was a dream to drive on the back roads. I did notice that the dual cam lobes has shifted a little bit and was wondering if this could be the issue. I had read somewhere on here that if the lobes were not perfect it was a nightmare to drive. Below are some pictures of the setup when the truck was in a straight line.
