I have squeek coming from my truck only when iam at a idle speed going down the highway but not when i am accelarate

Dude i have the same problem i have an 02 taco and it sounds like a banshee is yelling when i mob down the street its your drive shaft I've gone through my u joints and my center support bearing and it is your.drive shaft twisting i know it sucks to hear but it solved my problem

I do not know the answer to this problem, however I am in the same boat. My 2000 tacoma prerunner has recently started doing the exact same thing. No noise on accelerate, idle, or when sufficiently warmed up (20 minutes or so after driving). What I do know is that it is Not my brakes as I have relatively new pads (<1 year old) and Not the belt (i had it checked). Because it does not make the noise on idle, this makes it terribly tricky to track it down. So, if anyone can help us solve this problem it would be greatly appreciated.
