"Rushing" air noise up the "A" pillar and/or "rustling" noise above door openings in headliner.

REPAIR PROCEDURE:
This bulletin involves sealing the upper load beam and "A" pillar and/or sealing the roof rail body seam.
Rushing Air Noise Up "A" Pillar
1. Raise vehicle on a suitable hoist.
2. Remove front tire and wheel assemblies.
3. Remove two rear-most screws from the plastic wheelhouse splash shield and pull down to access upper load beam.
4. Remove the upper load beam "stuffer bag" through the access hole (if present).
5. Fill the load beam cavity using household aerosol foam sealer/insulation. It will be necessary to add an extension (12" to 18") to the application tube supplied with the foam sealer to reach into the cavity. Clear plastic tubing of the appropriate size works well for this.
6. Install the front wheelhouse splash shields and tire and wheel assemblies.
7. Pull out on top of "A" pillar trim to disengage the top and center clips.
8. Fill the lower "A" pillar using household aerosol foam sealer/insulation through the center attaching clip hole.
9. Install the "A" pillar moldings.
NOTE:
WHEN FOAM SEALER/INSULATION IS APPLIED IN COLD CLIMATES VEHICLE MUST REMAIN IN A HEATED AREA FOR 2 HOURS TO ALLOW FOAM TO CURE.
Rustling Air Noise Above Door Opening In Headliner
1. Remove roof rail molding from vehicle.
2. Seal any gaps in the roof rail body seam with Mopar Silicone Rubber Adhesive Sealant, P/N 4318025.
