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 Preliminary Information communication provides information to the technician about vehicles that have grease leaking from front hub bearings. Technician should not replace the bearing for grease purge. Technician should be advised to not clean the purged grease from the area immediately on or adjacent to the seals because this grease provides additional protection. Technician should only replace the bearing if the seals show visible damage, bearing endplay is greater than 0.005" or 0.13mm, bearing exhibits rough rotation, or bearing exhibits abnormal noise.
