B20008
Service Bulletin/Repair Instructions
Due to a customer complaint of a cracked spring post, an internal quality inspection found that a galvanic barrier had not been installed between the galvanized Aeroskirt Spring Posts and the aluminum mounting plates on the bottom of the trailer. Over an extended period of time, this can lead to Galvanic Corrosion between the two mating surfaces. This bulletin outlines the installation of a barrier between the two disimallar components. It is also possible to damage fasteners while removing the Spring Post when performing this bulletin. Even though each panel of the Aeroskirt is tethered to the trailerâÂÂs underside, additional screws will also be added as part of this repair to ensure proper and adequate resecurement of the Spring Post assemblies.

Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
