Loose Steering Column

OP, bump steer you say? You may have unequal lengths of the tie rod ends.

Measure the lengths of the exposed threads on the tie rod ends from the jam nut along the rod inward toward the engine to the point where the threads end. There should be an equal amount of threads on both sides, with the maximum being 1 or 1.5 thread difference IIRC. Some alignment techs have been known to make the adjustment on only one tie rod end.

 

Update! After takingn it to get aligned after 4 times truck is driving wayyyy smoother than before. Handling is a lot tighter as well. Still light loose feeling but at highway speeds everything feels nice and tight.

I specifically asked to set the castor at 3.0 and my toe and camber at 0. Seemed to work for me! thanks again everyone!
