My rear end makes a squeaky, whistling noise also. I'm pretty sure it's not my brakes. I hear the noise in 1st, 2nd, and in reverse, especially going over bumpy or hilly areas. Could this be the bushings? or what else could it be? I described the problem to a service guy and he didn't have a clue what it was. I need to figure out what the problem is before I can fix it.
