How about the tire/wheel questions?
When/what conditions result in feed back?
Does the steering shaft down by the gearbox still have its factory isolator in place?

If you hit a small stone laying in the lane with the right front wheel for example, when the tire hits it do you feel that in the steering wheel it tries to pull it to the right?
Or asphalt roads with those deep tire grooves where heavy constant traffic has created u shaped ruts in the lane, does your truck grab those ruts is hard to maintain a straight line in them?

Ok to a great degree that is an alignment issue.
Not enough caster I believe but needs everything checked and set if hasn't been already done.
If it has been done it needs more work.

What is the part number of the drop pitman arm and how much drop on the track bar bracket?
If the track bar is stock, are the bushings original? If not, they should be changed...preferably with something stiffer than rubber...polyurethane or harder.
There is a good chance that what you are experiencing with the wondering is called tire rod roll.

The pitman arm came on the truck when it had the lift. The track bar bracket did too. I cut and rewelded it to get them parallel. Trackbar has moog bushings. I read a little on tie rod roll. I'll read some more on it.

The drop pitman arm is likely not needed for the little amount of lift. But it does help improve the angle that the drag link goes into the tie rod. If you have it, I'll share my research, my opinion on the the only two feasible solutions, and the solution I am using for now.
It is critical to match the right amount of track bar drop with the pitman arm drop.
With the FD400 drop pitman arm the stock track bar location is too high. Duh, but I'm illustrating a point...
The steering wheel would saw left and right over bumps and gullys.
A 3" track bar drop was too much. The steering wheel would saw the opposite direction than before, but the movement was not near as much.
A 2.5" track bar bracket makes mine perfect.
