squeeks and squeels and unidentified noises
 

so, i have new ball joints ordered, and i plan on putting all new u joints on(both wheels, and both driveshafts) so i know im getting some noise from all of that. But now i am noticing a small and very slight squeel when i barley touch the throttle? i dont even know where to begin to diagnose this problem. Its like when im just on it a little kinda to carry speed, not to go faster or anything. I dont hear it at idle or when i get on it. any ideas as to where i shoul begin looking would be great thanks guys
