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.
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:
- Remove the door trim panel. Refer to Front Side Door Trim Replacement in SI.
- Peel down the door water deflector enough to access the inner door.
- Remove the front door lower speaker. Refer to Radio Front Side Door Speaker Replacement in SI.
- Inspect the gap between the inner door beam and door skin for voids in the adhesive.
Tip: Use of a trim stick, or equivalent tool, may help to work the sealer into the gap.
- Add a bead of *3M Windo-Weld Ribbon Sealer P/N 08611, or equivalent, to the areas where adhesive is missing. Work the sealer so there is a continuous bead in the gap from the rear of the door beam to the front.
- Reinstall the front door lower speaker and test to make sure the rattle noise is eliminated. Refer to Radio Front Side Door Speaker Replacement in SI.
- Reposition the water deflector and reinstall the door trim panel. Refer to Front Side Door Trim Replacement in SI.
