okay so maybe my truck just sucks but i can NOT get that stupid fill plug off of the 208 transfer case. any tips or anything about getting it off? i have the 1 3/16 socket size but it keeps slipping off because the stupid head of the bolt is like 2/7 of an inch thick or something reciduloucs. theres a little rubber washer it looks like that is underneath the bolt. i tried spraying it with silocon spray but to no avail. the bottom one loosens all easy. any advice?
