If moving the spacer doesn’t help.
Do you have an angle measure to measure Caster on the top of the knuckle ball joint?
just curious to others that do more if this. Would It be helpful to measure the caster (angle of end axle) at the knuckle? If it’s bowing that much it has to be a significant difference.
You went to Ranger school, so you’re a glutton for punishment. Put the stock springs back would be an extreme, set it down, and measure angles.
I also thought read about the front Drive Shaft getting rolled when working on front suspension. I’d consider pulling the front Drive Shaft, loosening CA bolts and jumping up and down on the bumper. Measure the angles again and see if it corrects.
Long shots, but you’ve got a frustrating deal.
That kind of frame work most likely is the culprit, and lift amplifies it possibly.
