  Summary

  Revised Freightliner Service Bulletin for Axle Flange Gasket Replaced with O-Ring. Revision removed steps instructing removal and installation of wheels. Daimler Trucks North America has released a new axle shaft to hub rubber O-ring (part number 11-30728-000) as a replacement for the paper gasket (part number 11-14418-000). The new O-ring will provide better sealing and is reusable. It is quicker and easier to use compared to the paper gasket, because using a paper gasket requires cleaning the hub when the axle shaft is removed.

  Summary

  Service Bulletin for Lengthening the Backup Light Harness. Though the backup light harness is long enough to connect to the backup light switch, it may be short enough that the wire seals in the connector can be stressed. Moisture entering through the seals can cause corrosion, resulting in a bad connection and/or failure of the switch. As a result, backup lights and, if equipped, the backup alarm, may not function when the vehicle is shifted into reverse.

  Summary

  Customer Service Announcement for a policy change regarding Detroit Service Information Bulletins (SIBs) will now have a 60-day expiration, starting on the release day of the bulletin. The intent of a SIB is to notify the service network of a major change to one or more service procedures. Do not save SIBs nor reference them for repairs, as they are uncontrolled and never updated.
