Question
makes a howling noise when driving.think its coming from rear of vehicle

Answer
Lift the car in the air, spin the tire while grabbing the strut spring with your hand, if the wheel bearing is bad and howling, the vibration can usually be felt through the spring. If the tread of the tire is choppy or cupping it will make a similar noise.
