It sounds like a bad bearing. Jack it up and use a mechanics stethoscope on it. This should allow you to determine if it is a wheel bearing or a pinion/carrier bearing. This method of checking it out can save lots of time. If you have any more questions I am here to help. Good luck, and Thanks for using Just Answer.

Some rear suspensions have what they call air bags that the rear end uses for springs. These have air compressors on them to keep the air bags full.
