I had this same problem, it sounded like a metal on metal rattle when going over bumps. Attached to the upper control arm is a small C clip that sits in a groove in the suspension. The C clip would rattle up and down whenever I went over a bump. I took a bit of hot glue and put two little dabs under the C clip to hold it in place. That eliminated the rattle!
Just bought a 2015 4R TE and I am loving it :driving:, hopefully this works out for you!
