My 2013 had the same problem, front end noise going over bumps and thru dips for years. Brought it to my brother’s shop multiple times, and he changed bushings, control arm and sway bar. Problem still there. Last year when it was in his shop again he had the car in the air and happened to push up on the front end of the car. The whole thing was loose. He put some bolts in tightened it up and the noise is completely gone. Do yourself a favor and lift up up on the front end of your Journey, the would be bumper area, I bet it’s loose too. I told another Journey owner this and he thought I was crazy and didn’t want to believe it until he lifted up on his front end. You won’t see it by just looking. Check it out!!
