It mostly has to do with trying to keep the truck straight on the highway. I have to constantly correct the steering as it likes to wander a bit once you get up around 60+.
My thoughts were that maybe the linkage parts were worn and give way while driving, the gears in the box are worn, or the power steering leak causes inconsistent pressure in the system.

There is also a decent amount of bump steering, but I think the truck doesnt handle bumps well so I'd try to tackle that first. I might have picked too stiff of a shock when I replaced them a year ago. She is pretty bouncy.
