Service bulletin CSR 3049

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

Altec Industries, Inc. has received notification from General Motors that a condition exists relating to motor vehicle safety, compliance, or emissions in a vehicle you possess that is equipped with Altec equipment. Navistar, the manufacturer of these vehicles, has determined that certain hex flange lock nuts used in several locations in the suspension joints in these vehicles were not properly formed and heat treated by its supplier. Improperly manufactured nuts can result in a loss of joint tension over time. A loss of tension in the suspension joints may increase the risk of a crash.
