I have a 1997 Park ave, when I go over a bump I hear a noise from the driver side, sounds like somthing is loose. I also hear it when I'm on the gas at about 60-70.

I have replaced both stuts and wheel hub.

Did you check the cv boot for tears?

Could be CV joint, however going over a bump would not cause a CV joint noise. Usually you will first here CV joint noise when turning tight under power. It will be a louder tick-tick or popping noise. You might check the ball joints or upper strut bearing mount.
