I thought my wife was crazy, but after turning down the stereo and taking a few slow, easy left handers I heard it! It sounds almost like a muffled cell phone ringing or a chirping sound when the wheel is steered slightly left while moving about 15-20 mph. Anyone have any experience with this? Sounds like it maybe coming from the steering shaft or maybe behind the driver head... I was going to check the PS fluid but though I would ask if anyone else has found a cause for this noise. Thanks for reading!
