Service bulletin TB-H816
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
This Technical Bulletin is for some Oshkosh S-Series Front Discharge Concrete Mixer trucks that are fitted with an optional Hendrickson Load Span Tag Axle (LSTA) may have seat-to-axle fasteners that were incorrectly torqued at the factory. The axle seats will continue to perform acceptably if this situation has occurred, but to ensure the long-term durability of the axle and axle seat connections, Hendrickson is providing these instructions for inspection and torquing of the axle seat fasteners. The affected LSTA assemblies are equipped on Oshkosh S-Series mixers manufactured between 9/1/2017 and 5/30/2018. Previous units (manufactured between 3/25/2008 and 1/20/2017) that were subject to and/or retrofitted per Hendrickson Technical Bulleting No. TB-H807, Rev B could also be affected. This Customer Letter notifies customers about the Technical Bulletin TB-H816.
