06 F-250 alignment issue

[doombugie]

After I had new 35" Nitto Trail Grappler tires put on my truck I been noticing the alignment was off so I took it in to get it re-aligned. Then I got a call from the shop saying that my casters we're out of factory specs and requires a bushing alignment, the tech that work on my truck said it won't affect my driving or tire wear. But after I took it on the freeway the steering likes to wonder left and right almost like its following every divots on the road. But on a flat surface roads it drives fine. Any ideas is greatly appreciated.

iaa it leveled or lifted, the castor angles of the balljoints need to be roughly
4* negative, or top joint tilted back from lower. if they are atop one another, think of a shopping cart with a wobbly wheel. when you drive the tire will want to DIVE into every rut.

if you have a 2.5" leveling kit you need the ICON Caster Sleeves. My truck did the same thing and wandered all over the road. The steering wheel also never snapped back to 0, i always had to move it back myself. Once i installed the caster shims, the truck rides better, doesn't wander, and steering goes back to 0.
