Svc 4wd light went on in the car after start-up, and i tried to reverse from my parking spot with the wheel turned and it felt like the emergency brakes were on. I stopped to check and they were not. i tried to reverse again and the car starts making a grinding noise and jerking motion as it pulls out slowly.
