Vibration and grinding noise

[hookoo3]

Update. Replaced the right rear bearing and all is good now. It was very surprising how much vibration was being caused by the worn out bearing. Droning noise and vibration are gone. Two things out of this experience I learned is that a stethoscope is invaluable in locating a worn bearing. Droning noise and vibration were associated with the bad bearing. Worst thing about this project was getting the springs back on the emergency brake. There must be a trick to it that I'm not aware about. Car runs great now.
