Thanks man, I have no idea what the different diff oils even do lol. That's sad but like I said its my first 4wd anything and I just been reading this thread as much as possible to figure out what I need and stuff. And this whole droop thing is also something new to me? I basically get what it is, Its setting it that I'm thinking about, let me guess more money for a Huddy set of blocks and whatever else is needed with them.
