Service bulletin SB31-043

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Freightliner Service Bulletin for Non-Airliner Rear Suspension Crossmember Fastener Change. With the start of production on March 2, 2020, the fasteners used to assemble the non-Airliner rear suspension (bogie) crossmember have changed. The rear suspension bogie crossmember gussets to the C-channel will be assembled with 5/8 - 18 fasteners. This change includes a revision to a higher friction nut that requires an increase in tightening torque. The new higher friction nut can be identified by its green color.
