Tightening the bolt on the steering box may help, but not likely. It sounds like you need to tighten your front spring shackle bolts. DO NOT OVER-TIGHTEN them or your ride will suck. I run WITH a front track bar and still had to make sure the shackle bolts were snug so the steering is responsive.
Give them a bit of torque and it should remove wander and torque steer.
