I have a 2012 Charger SE with 69K on it. All 4 tires are new with less than 300 miles on them. About 10K miles ago or so I started to get a “grinding” type metal on metal type of sound in the front end at low speed when turning left or right. I have taken it to the dealer here in NE Fla and they say the front end is tight and they don’t hear any type of noise. I hear it on all type of roads/parking lots but the dealer lot go figure that. Dealer says this car does not have grease fittings so that could not be it. I don’t see any tire rubbing anywhere and don’t have any vibration in the steering wheel. Please help
