So I changed the oil in my tranny and tcase today so I could clean the drain plugs and have a baseline to check for anything on the magnets next time I service them, and the fill plug for the tcase was pretty tight to remove all the way out (usually I can break them loose and then get them out by hand). The threads looks okay on the plug, but when I put it back it gave the telltale sign of snugging up...........and then all of a sudden getting loose again. I always use a 24mm 6-point socket on my 3/8" ratchet to avoid inadvertently over tightening drain and fill plugs, but even then it stripped loose. I got it back to a "snug" point where I won't have to worry about it coming out on the road, but if it turns out the housing threads are stripped, is there a fix I can perform without splitting the tcase and having to scrap the rear housing?
