Hey, I'm new to the forum just picked up a 98 Explorer XLT 4x4 SOHC last night. Anyways, I have noticed that the truck makes a squealing noise when driving from 15 to 30 mph. I let off the brakes and put the vehicle in neutral and the noise continues. It is timed with the wheel speed so I am thinking it could have something to do with the brakes? Also, at low speeds it makes a groaning sound when turning the wheel hard in either direction. I have noticed that it shudders a bit when braking so I am assuming the rotors are bad but would that cause these other symptoms?
