Trying to solve this for a year now

Try a new set of rotors, my go-to brand is POWERSTOP but I will use Raybestos if they are not available and I recommend new pads for them, since you have a pulsing issue. Your rotors are near the end of their use, sounds like they are due for replacement anyway

while doing the run out, did you measure both sides? the thickness?
rotors can get fat spots. those cause pulsing.

I'm assuming it's a 4x4 with rotors separate from the hubs. Before replacing the rotors I'd do one more check. Measure the runout and mark the rotor at the high spot, slide the rotor off, rotate about 1/2 turn, reinstall and recheck. If the high spot is the same the rotor is at fault, if the high spot moved about 1/2 turn, it's the hub.
