Unknown squeak while under a hard turn.

[Cerwin Vega Fan]

I have noticed that when I make a sharp turn or take a hard curve I hear a squeaking sound. The sound sorta sounds like the same thing you would hear if you had bad brakes (a high pitch squeal). The weird thing is this sound is even produced when I do not use my brakes. I was wondering is their any chance a warped rotor could cause this? I think one of my front rotors is warped, I just didn't think it could cause this kind of problem when the brakes were not applied.

Its probably axle end play. Common problem with this rear end. The GM fix is a set of caliper bracket shims.
