who thinks they know what this wierd sound is?

i think you guys are right about the diff. thats where i think i hear where the sound is coming from. but how did my diff already blow after one month? i dont even have brushless yet. is it because i have my slipper too tight? i love doing wheelies thats why i have it so tight. but someone told me you can have it very tight even like 1/4 turn to the tightest and itll be ok. and im sure you guys with brushless setups have waaay more torque than i do and can do wheelies at will and prolly have no diff probs.
so how did it cause this so i know how to fix it? and lastly, what if i dont fix the problem, can it ruin more things later? because my truck still runs perfectly fine other than just hearing that sound. should i just wait till it blows then replace it, just incase its not even the diffs?
oh hey i made this post in other forums, feel free to check what they said maybe that would help out. sorry, this noise is buggin the ish outta me..need all the brains i can get.
