Tacoma Screeching noise

My 99 Tacoma Prerunner V6 Auto, is running great but i hear a screeching noise, when i drive when you coast you can hear it , whe you give it light gas you can hear it, when you pick up some good speed you cant hear it, when you come to a stop the noise stops, its not a belt or nothing i checked that, i check brakes and still good sanded glaze off and pads and drums but still get the noise, i dont know what it is but its irritating me , wheel bearing ? somehitng else ?

 

How much front pad is left? Are they getting near the end of their life? Could be the wear indicators on the front pads that you are hearing.

 

belt

 

The pads look new, and if it were a belt you can hear it amoung start up and its not that

 

to me it really really sounds like a U-Joint
