I'll add those to the list. I do have a hum that is only noticeable while on the throttle. Not sure what it is at this point. Had the rear axle rebuilt and most of the noise went away but I still here something. I'm really convince its in front which all the front axle seals where also replaced. I can't really say if its worse on turns or not but their is no clicking that I hear. Can a water pump cause this noise?
