Service bulletin 3117

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

ON CERTAIN FLD MODELS BUILT BEFORE AUGUST 4, 2000, HENDRICKSON AERO CLAD BUMPERS HAVE HAD SOME PROBLEMS WITH VIBRATION ON THE ENDS OF THE BUMPER. WHILE THE VIBRATION IS AN ANNOYANCE, IT WILL NOT CAUSE THE BUMPER TO BEND OR FAIL. HENDERICKSON HAS REDESIGNED THE BUMPER TO MINIMIZE THIS PROBLEM. *TT
