1999 Chevy 1500 transfer case leak

[wreckdiver230]

i see the output shaft and it doesnt look like its leaking to me , the front differential uses 80 to 90 wieght gear oil , and i dont see that here. i dont know what that green fluid is ,my advise is to clean up that area , check diff and drive it one day then look again see if you can find the drip, just a thought is your cv joint boot tore
