## NHTSA's summary

Altec Industries, Inc. has received notification from Navistar that a condition exists relating to motor vehicle safety, compliance, or emissions in a vehicle you possess that is equipped with Altec equipment. Navistar has decided that certain International trucks built from January 2022 through August 2022 could have a specific hex flange lock nut used in several, not all, steering and/or suspension locations that may have not been properly formed and heat treated to Navistar's specifications and can result in a loss of joint tension as the vehicle ages.
