Thanks azruss, following your tip I've since checked the pillow block area out in my repair handbook and yes I am missing a couple grommets (4074483) and spacers (4074482). They actually go onto the cross rail to body stud.azruss wrote:those holes are oversized for a purpose. a large grommet with a sleeve goes there as a vibration dampener. it is also very easy to get the bracket on backward (ask me how i know this).
Looks like another little project to add to the list for when I'm next under the car.
