grinding noise

Got a 92 Pontiac bonneville SE ,

About a week ago a grinding noise started in the front . the faster i go the louder it got and turning left or right it would grind even more. So i was thinking it was the brakes. So yesterday i replaced the Rotors, Calipers and brake pads. But i get it all back together and the grinding is still there. Now i am thinking it is the Wheel bearing's.

Anyone have a clue?

Sounds like wheel bearing.

Ok , I hope that is the problem , Cause now today i turned the corner to get home and a really loud grinding/Ratteling bearing noise is happening.

Now is it a pain to replace the whole hub assembly ?

Marblesetter why dont you take it to SPEEDY OR MIDAS and get a free diagnosis as for the grinding and rattling could possibly be something else like a CV axle joint.
