The howling starts from the time I turn the ignition on, its coming from the rear passenger side, it howls even if the car is idle, a mechanic who checked out the car for me told me it was the fuel pump. Thanks for the tip on the recall, I just called the dealer and they said that I am entitled to the front brake hose replacement (will take care of that asap). I will try to change the diff fluid over the weekend hopefully it will make the ride a little more quiet
