I know mine had minor looseness in driver side hub, and wobble was terrifying if road hit at wrong angle.

honestly, you need to sit down and ask yourself:
did I have this before I lowered/raised my truck? if not - well, pretty much, you have answer. Any changes to suspension change factory geometry and may result in who knows what.

if it kicks into steering wheel, it's front end and might as well be relevant to tie rods. they are not bad to replace at all. alignment can not also be set true, if rods are loose.

did that shudder manifest itself right after you replaced rotors or it took some time? I had a Honda that was burning rotors, it will take her 2 weeks to warp them from new.

I'd also suggest checking on brake pad wear and rotors color. If it's bluish, you have dragging caliper....
