Some customers may comment on hearing a driver or passenger front side door rattle noise during high radio volume or high bass levels. The noise is most commonly described as more evident from outside the vehicle rather than inside.
The cause of this condition may be voids in adhesive (1), leaving gaps between the inner door beam and the door skin.
The graphic above shows an example in which a tie strap (1) was passed through a 15-20 cm (6-8 in) length gap where the adhesive was missing towards the center of the door.
This can also occur in the front and/or rear area of the door beam; with the condition sometimes more evident in the front area (shown above) where the radio speaker is mounted.
Inspect the front side door beam and door skin gap for voids and add a bead of butyl ribbon sealer in those areas following the steps below:
Tip: Use of a trim stick, or equivalent tool, may help to work the sealer into the gap.
