Service bulletin 20904
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
Certain MV Series trucks built with Feature codes 14GVJ, 14GVX, or 14GVY (Axle rear tandem, Meritor MT 40 series) and with 14UNU (Suspension, rear air tandem 6X4 IROS) may have less than optimal driveline operating angles and this procedure is intended to improve inter axle differential reliability.
