Service bulletin FSB652-005

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 some MACK CHU, CXU, GU, TD, LEU, LR, and MRU trucks built from 01/14/2013 and 01/20/2017, the V-Stay carrier bolt hole in the mRide suspension may become stripped, causing the V-Stay torque rod bolt to pull free from the carrier housing.
