Service bulletin CB16-E-001

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

In some 2012-2016MY Isuzu Stripped Chassis (Reach Vans) and 2011-2016MY NPR-HD diesel trucks, the original factory-installed grease in the front wheel bearings may degrade under certain circumstances. If left unattended, the front wheel bearings could eventually seize or loosen. Typically this condition is preceded by a noticeable growling noise and can be avoided with timely servicing of the front wheel bearings.
