Front End Pop/Clunk Sharp Turn

[cchiodo]

1999 GMC Sierra 1/2 ton 4X4 240k miles

 

I am hearing a loud single pop/clunk from the front end passenger side when I turn the steering wheel sharp LEFT ONLY in forward and reverse.  I can replicate the noise nearly 100% of the time if the truck is on a moderate to steep incline.  This only happens at slow speeds.  I feel next to nothing through the steering column.  I hear the most out the front passenger window and feel the pop/clunk through the floor of the cab.  I have replaced the intermediate steering shaft with the updated GM part.

 

Any direction would be really appreciated.
