Awd noise

[Boilermaker57201]

I have a 97 explorer with the 5 liter v8, full time awd. I hear a clunk when I turn to tight and if I'm on pavement I can hear the tires chirping.Obviously the differentials are fighting each other, what ways can I narrow the cause down.

Transfer case contains a small "viscous clutch" which absorbs speed differences between the front and rear wheels, while driving the front. In all likelihood, it has gone bad and is locked-up, not allowing the "oil-slip" action to occur. Trouble in either front or rear differential can cause a locking effect, for example, broken locked-up differential gears. Such a condition is rare.

If you are able to, remove the front driveshaft, and test drive. If the binding is gone, you need transfer case attention. Or, just drive using rear wheels only. Not a great idea, though, as if broken parts find their way into the oil within the transfer case, bearings and other parts will be seriously affected. imp

Ok so next question is if I have to what is the interchangeably on the transfer cases. I have an awd powered by a v8. Are there limitations for finding a replacement if the transfer case is in rough shape
