Official 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.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
