I have been having a very loud and constant sqeaking noise coming from the rear of the car. Initially the sqeaking noise would only come from the rear passenger side but now it comes from both sides. I took my car to the dealership, they performed the rear axle TSB as well as cleaned the rear brakes. The noise came back after a week. I hear it all the time under 50mph, its a little embarassing driving by in a brand new infiniti as it sqeaks by. I was wondering if anyone else had this same issue and what they did to resolve it. Thanks.
