I am getting an intermittent chirping noise that changes in frequency with the speed. It is coming from my right rear wheel. I took the wheel off and when I turn the hub, I can hear a faint noise. It seems to be once with every revolution, but it is so faint when I do this I may be missing some.

Could this be the early stages of a failing bearing? Do you think it would be safe to drive the car, or should I dry dock it until I can get the problem resolved?

Thanks,

Dick Schneiders
