I found where the extra fluid came from; I checked the transmission fluid level. It had at least 2 extra quarts in it. I have everything back to where it should be. I still have the noise I was looking for, but not as pronounced.(and performs much better) I am thinking the switch motor is going bad and hanging up in between 4X4 and rear drive some. So much for using Jippy lube for service.
Any thoughts on how much damage this may have caused over about 2500 miles? This truck has 191,00 miles on it. I replaced the engine at 161,000. It has no leaks, so I don't check levels as often as I should have. My bad...

The extra fluid removed from my transfer case and transmission.
