Re: Constant Griding Noise from Rear!?
The bearing is only going to start making a noise as it develops play in the bearing. You can jack up the car and rotate the wheel and see if there's play. It will make a roaring sound while driving that gets louder as the wheel goes faster if the bearing is going bad. Normally a grinding is the backing plate getting bent and rubbing on the rotor after you worked on the brakes or it could be the shim sliding off and grinding onto the rotor. This happens when you don't make sure it's fully bent onto the brake pad so that it won't come off and slide to the rotor.
