It's kind of pointless to try to diagnose something when there are a bunch of related issues that need to be corrected. You should not even be driving the car with the problems you describe. Odds are that the problem will be solved when you make the necessary repairs.

 

Axles are like 60 bux at the autozone by my house, and its in stock, and i get a discount on it lol. So if you do end up needing one let me know the prices you find, i might be able to get it to you cheaper by shipping it.

But wheel bearings dont usually make that noise.... Could be an axle or rotor, maybe he bent the spindle and the hub/rotor is slightly rubbing?
