Service bulletin 511493
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
Mercedes-Benz AG (MBAG), the manufacturer of Mercedes-Benz and Freightliner vans, has determined that the torsion bar on certain Sprinter vehicles from platform 907 (VS30) was not bolted to the torsion bar linkage in accordance with design specifications during front axle assembly by the component supplier. The shim on the torsion bar was incorrectly installed between the nut and the torsion bar, rather than between the ball stud and the torsion bar. Due to the incorrect assembly, the torsion bar may not meet operational strength requirements. Settling effects may occur between the journal flange and the torsion bar. These effects reduce the bolt preload at the connection, which increases fatigue on the journal and could lead to a fatigue fracture of the journal, increasing the risk of a crash.
