Hey guys looking for advice before I move forward. When I drive my 2011 dodge Journey awd there's a humming that comes from the front. Now when I turn right, the sound seems to go away, when I turn left it gets louder. My first thought was the hub on the front right was bad, it was replaced. Then I found the ball joint was loose on the same side , I changed it out. Still the humming sound won't go away. Experience tells me to change the hub on the left side. Can you guys think of anything else that would be causing the sound? Thanks a lot!!!
