Clunk-clunk Dana 60 front, kingpins?

[Americanrider]

I have this yet unidentified Clunking noise coming from the front D60 under my 85. When sitting still and turning the wheel and changing direction in parking lots at slow speed is when I hear it. My first guess is Kingpins gone bad. Anyone have a method for checking the D60 Kingpins without tearing into the axle? It seems to be coming more from the right side than the left. This is in 2wd drive mode, front axle not engaged.

Also noted is hairline heat stress cracks forming on the rotors. Due in part to whimpy rear brakes (those I fixed already) How long can I still run the rotors without worry or should I just change them out now?
