My 07' has 64,000 miles on it and I wanted to change out the differential oils, transfer case and do a drain and fill on the trans. My plan was to do 4 drain and fills over 10,000 miles and to change the filter on the first one. Well I pulled the pan off and when I was un bolting the filter there were 3 studs with a nut on them with the rest being hex head bolts. One of the studs sticking out turns instead of nut turning. How do I get that nut to break loose ? the other 2 studs broke loose and as far as I could tell there is nothing holding the other end,but they did tighten back up. Thanks for the help!
