Trying to determine orgin of squeaking

[ZBTstang]

Ive been ironing out all the kinks since I bought my TJ in october (expensive ironing at about $1200 by now, but anyway). Ive noticed now that I have a loud and fast squeaking noise coming from underneath. It sounds like something is turning really fast and just isnt lubed right. I wish this site had a place to upload sounds. This only happens when im actually driving, not idiling. And will happen sometimes but not all the time. I know this is all pretty vague but any educated guesses you can give me on what you guys think this is, if it sounds serious and or expensive, and if I can correct it without going to a shop, would be VERY helpful.
