# Service bulletin 122\-T8T7L\-12

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.

Subject: Bleeder screw for front axle lift system Situation: There is a possibility that the bleeder screw for the front axle lift system was not tightened to the prescribed tightening torque on the affected vehicles.
