This sounds ridiculous I know... But...
You need to center the porporioning valve (spelled wrong but you get the idea).
You will need to do this with a good OBD2 scanner. Like a snap on solice or comparable scanner. It is usually in the main BRAKE menu.
I had the exact same issue on my 03 2500HD after changing everything out, control arms, front able stubs, rotors, calipers, and wheel speed sensor cradles, bearing hubs, everything... After fighting with it for 2 weeks and finally replacing the master cylinder and power steering pump, someone said center the proportioning valve, at which I scoffed thinking it was a joke like topping of blinker fluid or changing the muffler bearing. Because I am/was old school, pre-computer controlled vehicles I fought the urge to look stupid at the local mechanic shop and finally asked if this was legit. It is.
Do it, it should solve your problems.
