there is a "center differential" that allows front and rear drive shafts to
turn at different speeds in turns. It is a fluid coupling. In older Jeeps
it was mandatory to change the fluid a specific intervals. I'd check with
dealer to find out if a fluid change is apt to solve your problem. I would
not just ignore the problem, lest you do some damage over time.
