Finally got to this, some guys I did a website for checked it out, found maybe 2-3 inches play between the front wheels at turning. Lotsa noise in the diff and the transfer case. Also found the diff had been opened before by presence of red silicone.
Scheduled a full day wednesday to open both up and take a look, then will have the verdict on this issue. In the meantime for others with the same symptoms, it's either heavy wear in front diff or t-case, possibly/probably caused by not changing fluid.
