So for an update,
I replaced the drag link to no avail. It really doesn’t feel like it’s coming from the rear. I’m not saying it isn’t but it doesn’t feel like it. It seems like the front tires want to point either direction slightly besides straight, and it likes to dive whichever way the road leans. Still feels like an alignment issue to me but hard to believe that after 2 different shops. Open to other suggestions... -
First thing I would try is to bring your tire pressure up another 10-20 psi, depending on the max cold PSI on the casing (I don’t suggest going over the stated pressure). Even soft sidewalk tires will stiffen up with more pressure.
If your already at your max there, then I would look toward wheel bearing torque. They should have re-torqued the steers when they did the kingpins. But that doesn’t mean they did. But I didn’t read anything in your post so far that sounds like anyone has touched your drives bearings.
If your still searching After that I would get a good set of lights and eyes on all your frame crossmembers bolts and try to find something loose.
If all that checks out, then I’m really suggest off the wall and look at your cab suspension. It could be if your cab mounts or cab torsion bar is loose your actually feeling the cab move. If it’s moving, it’s attached to the steering wheel and that could be causing some of your issues...
But after that...... I got nothin...♂️ -
Seems like you almost changed everything why don't you change out the front tires, or maybe the rim is a little bent.

That would normally indicate excessive toe on the steer axle. Is this an air tide front end? Air ride tends to have a walking feeling to it. What is your average steer weight? Normally that’s not an issue. If you have a Dana steer axle and run light on your front end, it won’t be pleasant.

I haven't seen any difference in a fuel MPG, only difference in how truck rides. The XDA5 gives you a smooth ride, I love it. Also, XDA5 is a bit noisy tires, depends on a surface you drive. I got used to that noise so it doesn't bother me at all.
