I had a rattle from the rear on MIZR once after getting him back from service. It was one of the rear skirts had not been correctly "hooked" back on to the clips at the top of the skirt. Also I have had to slightly "tweak" the clips on the skirts after removing them several times. I just push in on the end of the clips and all is well again. You really dont want to lose a skirt as My son lost one on the wifes Insight, $360.00 later it is back on.
