I was thinking about it ... But I'm afraid of cracked transfer case those plugs are tappered already I don't want to add thickness ... I know it's minimal but liquid seems a little bit safer
I think it’s fairly important to clean off the buildup of Teflon tape and/or thread sealant, particularily on aluminum transfer cases and then re-apply a fresh coating. Make sure the drain plug on the transfer case has the integral magnet.
