Well, what it sounds like is the cv axle joint came apart because you had a split boot and the grease came out over time, then the joint started to click, then you didn't fix it so it came apart. Did it put a hole in your tranny? I have seen this before. Your 18 so this will be a learning experience for you. Maybe you had a small tranny leak and let it run dry? I am trying to understand you to be honest. 32 inch nut, I think, is at the end of you cv axle, good luck getting it loose, it either takes a good power air tool or alot of weight with a long leverage bar. Once that is loose then take off the brake components then the nuckle sp? piece loose then stick a flat big screw driver in between where the axle goes into the tranny and pry it out. Then you need to take the old shaft seal out and put a new one in. Then replace the axle with the new one. I
If you messed up your Tranny you will be taking out your axle anyways so it can be replaced. Good Luck.
