Clunk Under Floor During Hard Turns?

[Sundown94]

Agr thanks for the response. Just to clarify, the hard right and left turns are not tire squeelers, but more like if I am coming up to a left or right turn and the traffic light is about to turn red, so you go a little faster through the turn to make the light. If stop first and then make a slow turn, no clunk. Also, there is nothing inside the vehicle to slide around (because I am so anal about keeping the truck clean and empty).

H2R, thank for your reply as well. Are you serious about an axle shaft going??? Is that common and, more importantly, dangerous???? I have never done any off-roading or done anything that might put extreme pressure on the axles to cause them to fail prematurely. I can say though that I have 80,000 miles of normal local and highway driving. Could it be a CV joint?

Thanks in advance for any additional feedback!!
