Alright, alright... 
Replaced the left front hub yesterday, again.  I missed my cruise control. 
  
Lo and behold replacing the O'Reilly's OEM (made in China) with a factory (made in the USA) hub solved the lunging issue. 
I went to O'Reilly's with hub in hand and explained and accepted it as a warranty return.  
  
I inspected the hubs prior to installing, nothing really to note.  The Chinese hub does have a heavier casting, its thicker and conically shaped adjacent to the hub.  The factory hub, definitely less girth and more symmetrical adjacent to the hub.
