I have a big problem i think. When i am driving my car in the highway, i am hearing an annoying humming sound coming from my rear wheels. It is almost like a metal to metal sound that comes in and out continiously. It is like you have bad brakes and the brake pads are touching the drums,...this is the best way to explain the sound it makes.
Can it be wheel bearings? If so, are they expansive and easy to change? I just want a quite ride and i am no where close to it.
Can it be tires? I am dying over here.
I drive 20 miles each way everday to Bayridge Brooklyn area, an i am about to loose my mind with this problem!!!!!!!!!!!!!!! PLEASE HELP
