Does anyone know where that article is that discussed all the rattles that come from the XB and how to fix them? I need some serious rattle help!

 

There are many, but select red "search" button, and type in "engine rattle", check the "all terms" block, and catagory Scion xB. It lists 39 (only 1 page), but all do not address the rattle in the way you are interested. Good luck!
