I have a 2009 R/T 5.7 automatic and I noticed a squeaking sound coming from under the car. Here are they symptoms It seems to do it under acceleration at around 60 mph and above Does it when I'm coasting at 60 or above and hit bumps I can't really tell, but it sounds like it might be coming from the rear of the car Tried to hear it with the windows open but couldn't Could hear it when the windows were closed Also made a weird engine noise when I was decelerating going down a hill and then stepped on the gas, almost like the muffler came off. Not the normal acceleration exhaust noise. Any help would be appreciated.
