:yesnod: Wow, this really works. No more liftgate rattle on my 2010 Escape. I used a slit piece of shrink tubing (seems to be fairly durable stuff), glued it to the striker post with spray adhesive and put two wraps of tape over that. As the previous poster said, so what if I need to refresh this fix every so often.
As luck would have it, I also fixed a rattle behind the radio that has been there since we bought it new. Drove us nuts. Been to the dealer several time (of course), and you can guess how that went

. Anyway, I finally decided to take the bull by the horns and pulled out everything from the center dash area (radio, HCAV controls, upper air ducts, etc. Finally found the source of the problem. It was a loose screw that holds the metal radio frame to the left center AC duct (among other things, I think). Once I figured out how to get to the damn screwhead to tighten it (nothing trivial), the problem was cured.
