This is my daughter's car. I thought it sounded like a wheel bearing but after jacking the car up none of the bearings have any slop in them and turn easily with no noise. I also noticed when letting off the gas it slows down faster than it should. Almost feels like the breaks are slightly engaging. Brakes look fine, emergency brake is not engaged and all four tires spin freely. Transmission?? Kinda has me stumped at the moment. Any advice would be appreciated.
