remove the FILL
plug on your transfer case BEFORE
you remove the drain plug!!!!!!!!
If you remove the drain plug, and then can't remove the fill plug, ...well, you get the idea. That's the only way you could possibly mess up the job. Otherwise, what they said.
This was my problem, I tried using a crescent wrench to loosen the drain and fill plugs,drain plug was okay, fill plug was put on with the gorilla grip from previous owner. my solution was to go to sears and buy a 30mm wrench walked out to the parking lot and loosen the plug, walked right back in and returned the wrench
now my crescent wrench works just fine!
