This lock nut is used in several joint locations on a chassis: o pitman arm pinch bolt joints o steering gear mounting joints o front axle U-bolt joints o front and rear spring eyes o certain rear spring tie • All vehicles contain at least one suspect bolted joint, but due to vehicle configuration, not all vehicles will require all joints to be repaired. Part 573 Safety Recall Report 22V-869 Page 8 The information contained in this report was submitted pursuant to 49 CFR §573 FMVSS 1 : NR FMVSS 2 : NR Description of the Safety Risk : Improperly manufactured nuts that did not immediately fail during vehicle assembly can result in a loss of joint tension as the vehicle ages. This nut is used mainly in suspension (front/rear) and steering gear joints. Loss of tension in these joints may affect vehicle handling which could contribute to a vehicle crash. Description of the Cause : A tier 3 supplier was found to not have adequate heat treat furnace controls to ensure consistent nut surface hardness. In addition, this supplier’s tooling was found to be worn, contributing to mis-formed threads. Identification of Any Warning that can Occur : A general ‘loose’ feeling when driving.

As of this time no warranty claims or field failures have occurred in the suspect population. Description of Remedy : Description of Remedy Program : • The remedy will involve replacing all suspect hex flange lock nuts with hex flange lock nuts made to their design specifications. • Navistar’s plan for reimbursement of pre-notification remedies, on file with NHTSA and dated 05/06/2022, applies and reimbursement instructions will be included in the customer notification. How Remedy Component Differs from Recalled Component : The remedy hex flange lock nuts are made to the specified form and surface hardness where the recalled hex flange lock nuts were not. Identify How/When Recall Condition was Corrected in Production : 08/26/2022 – Navistar quarantines all vehicles at all plants and begins use of hex flange lock nuts manufactured to their specified design values. Recall Schedule : Description of Recall Schedule : It is estimated that the Customer and Dealer notification letters will be mailed by 01/20/2023.
