Excessive rear rattle, especially on worn road surfaces.

What is your question?

The rattling stop when very light pressure is applied to break pedal. Trouble started after a Ford oil change, which included car inspection (fluid levels,brakes,tires,tire rotation). Rattle was minor at first, but has really gotten louder. When it first started Ford dealer took a quick look on my next oil change and said they could find nothing. If I made an appointment, they could check it further. I didn't have time.
