Can someone please elaborate on this. Im 99% sure my Z71 has developed this. Also, this is not the typical intermediate shaft clunk. Its different.

sounds more like ball joints.

 

I had this happen for about two weeks on my 2500, thought it was ball joints or tie rods. Stopped doing it about a week ago. Dunno!

 

I've always wanted to know this too. My truck did this for a while but I took out the the transmission crossmember and member under the engine, cleaned the contact point and put it back together as tight as I could make it. Pop stopped.

It was much more prevalent in the summer though.
