take a look underneath, look at heatshields and your exhaust. anything with scrape marks investigate.

probably isnt whats causing your rattling, but worth a look if you recently scraped or something... part number 10 and 12 were bent back against frame.... not too clear in the diagram but one end clamps to both pipes, the other bolts to the back of the tranny mount.
Alright cool I'll check that out, thanks a lot man.
