OK so as I left for work this morning I hear this squeaking noise coming from the driver's rear side of the car. This squeak occurs when the car is rolling only and it doesn't matter if it's bumpy or even ground. The sound sounds a lot like an old squeaky tennis shoe. Twice on decel in gear with me not being on the brakes I heard a chirping noise that sounded exactly like a little bird chirping in the morning. Can someone please tell me what is wrong with my car, how to fix it, and how much I'm looking at having to spend please? Thanks in advance for any help
