82Stang, thanks for the response. I did measure the front rotor thickness with a mic, that's how I knew they had plenty of life left in them (they are well over min spec). But as I stated I checked runout too, with a mag mounted dial indicator. This check will show the warpage in the disc surfaces. I listed the runout values above. The runouts are kinda small to fell the heavy pulse that I do when driving the truck.
Just looking for ideas on whether it might be something else (maybe even non-brake related). Let me know. I will post back I'm able to solve it.
