Service bulletin SF183AB

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.

SOME VEHICLES EQUIPPED WITH THE DS402 AND DS404 AXLES HAVE AXLE SHAFTS TO SUIT SHORT BARREL HUBS, BUT THE VEHICLES WERE MANUFACTURED WITH LONG BARREL HUBS, RESULTING IN INSUFFICIENT AXLE SHAFT SPLINE ENGGEMENT WITH THE DIFFERENTIAL GEAR SET.
