What are you 'growling' about?? Your posts were made in more of a statement type of phrasing , not really sounding like a question about what to do to get the noise to stop. You replaced the hubs and that didn't make a difference ....more to the story?? Conditions? Then question , which usually ends with a ?(question mark) good evening............nevermind.......
