Service bulletin 220-HM-WallaceFo

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

Wallace Forge, the supplier of our 20,000 lb. Adjustable Cast Coupler, sent us a notice of recall as required by the National Traffic and Motor Vehicle Safety Act. The recall concerns the internal ocking mechanism not meeting the correct specifications resulting in "excessive play" and, in extreme conditions, could cause the trailer to become uncoupled from the tow vehicle.
