So i just put in my 4th gen rear, off of a lt1 car with the 1le rear brakes, new rotors, new pads, rebuilt calipers.

Gradually im hearing this squealing sound, i just had an axle seal replaced on the drivers side, but this squeal is from the passenger side it started while im driving all the way to Florida. I just installed the rear end about a week ago, never heard this sound before. It got gradually worse, than was quiet. Seems directly related to the speed and if the brakes are applied. At low speeds its annoying as all hell, but at high speeds its barely noticeable most of the time. And if i apply the brakes, the sound goes away, but the second i let off the brakes, its comes back. I took a peek under there but i dont see anything out of the ordinary. Any clues as to what it is? i did a search and found a bunch of posts telling me to change my pads, but there brand new so i know there not worn down already.

 

Anybody have any clue what this could be?
