I've had multiple alignments done within the past few years, and by various places too to rule out mechanic error.
Our issue is similar in the sense that if we hold the steering wheel at a certain place, it'll drive straight. Mine also moves to the right once I let go, which causes the truck to veer right.
If you figure out what it is, keep me posted.
Oh okay. I'm sorry. I missunderstood your post. I will definately keep you posted. I will be checking the algnment soon, and when I return from my trip, I will start tearing into the suspension. If I notice anything suspicious, I'll let you know.
P.S check your LCA bushings
