Grinding?
 

Hi my name is Candy and I have a 94' Cadillac Sedan Deville and when I am driving there is a really bad grinding noise coming out of the front right tire.It stops grinding when i turn left. Could this be a wheel baring? Or my brakes. I have a ABS light on my dash could this have anything to do with it. AND... when running the car there is a clacking/rattling sound coming from the exhaust around the cat converter.It sound like an exhaust leak too. It throws the code PO48 which is something to do with my EGR valve. It wont get up an go sometimes, like its lagging for just a sec. getting out into traffic... i need help :confused:
