Hello I have a question I wanna know what could be wrong. Dodge Charger hellcat my girl was driving fine in the freeway, she got off the freeway and called me to tell me come outside the house because the hellcat was making a ugly sound from the rear driver side wheel. It sounded like if something was hanging off underneath the vehicle. I checked underneath and there was nothing stuck nor any damage on the wheel. When she try to drive it wouldn’t go it would just raise the rpm. The other wheels are fine but the back wheel seem to lock and wouldn’t move. I been told from my friends it can be the The rotors are the wrong size but said probably sound like it was stuck. The calipers is stuck just pushing the pad into the rotor. What could it be?
