Metal on Metal Grinding Sound When Driving.

Yesterday my car started making a metal on metal grinding sound when driving, the sound stops as the car slows down to almost a crawl. Also the sound is not changed much when brakes are applied so I assume its not the braking system. Could it be a bearing?
Any suggestions would be appreciated.
Thanks
Arthur

Lift the car up and turn the wheels by hand, maybe you can isolate it.

Even though you think it is not the brakes, it still sounds like the brake pad to me. Are your pads work out? If so, you may be hitting the metal warning tab already.

i believe that when the pads get worn out the screech when the brakes are applied only. If you ignore this and they get even more worn, they will screech all the time whether braking or not.

hope this can help you figure it out

The warning tap will make contact with the edge rotor no mater if you apply the brakes or not. it is sinply a depth thing. When the pads get too thin the metal tab has no choice but to contact the rotor. However, it is hard to say if this is the case with Arthur because it would be more like a load metal squeel rather than a grinding noise. A wheel bearing would be more like a hum.

Well I have narrowed it down to the wheel bearing or the inside brake pad. But im guessing its the bearing for two reasons. The sound does not happen when the car is in reverse, and my brakes are decently new and have not had any of the low brake "warning" squeals.
Once I get that damn rotor off I should know.
Any thoughts on how to get the 36mm bold off? I have tried WD40, Heat, manual impact wrench, ect. I will try my air impact wrench tonight.

i am assuming that 150psi is more than enough consitering I have it set to 60psi for most stuff.
