Since I have saw quite a few people talking about a rear end noise over uneven surfaces, I wanted to share the resolution to my problem. As some of you already know, my car spent over four weeks with ford trying to fix this problem, and in the end they called the regional service engineer to fix the problem.
This is what they did verbatum from my invoice:
"Popping noise from rear suspension.
Rd test to verify with FSE. Remove all rear interior trim and backseats. Remove all trim in trunk. Abnormal diag with chassis ears. Remove rear swaybar and links. Inspect rear subframe for damage welds. Incomplete and weak. Replace Rear subframe include trim r-r rear brakes upper and lower control arms and axles. remove rear diff time to blend brakes and reinstall all seat"
I hope this helps with what might be the problem. I don't know what some of that is, but hopefully the more mechanically inclined it will help. What does the r-r mean? I didn't get that.
