IMPORTANT SAFETY RECALL

This notice applies to your vehicle. Your VIN(s) can be found on the bottom or back of this page.
Subject:

Safety Recall: 24PBG: USK Drag Link and Tie Rod End Ball Stud Heat Treatment
NHTSA: 24V433
EXPIRATION DATE: NONE

Dear Peterbilt Customer,
This notice is sent to you in accordance with the National Traffic and Motor Vehicle Safety Act.
Peterbilt Motors Company has decided that a defect which relates to motor vehicle safety exists in certain model year 2025 Peterbilt 220,
520, 536, 537, 548, 567, 579, and 589 vehicles manufactured from 04/11/2024 through 07/03/2024 with USK drag links and/or front steer
axles with USK tie rod ends. Supplier USK used a heat treatment process that may have resulted in ball studs that failed to meet the
supplier’s hardness specification. Affected ball studs may have been incorporated into drag link assemblies and/or tie rod ends. If the ball
stud fractures, the driver may experience a loss of steering and reduced vehicle control, which may increase the risk of a crash. Peterbilt
recommends that affected vehicles are not driven until:
1.
or
2.

The components are inspected and are proven to be outside of the suspect Julian date range.
The components are inspected and replaced if found to be within the suspect Julian date range.

What is the problem?

Certain vehicles may have a tie rod or drag link with a ball stud out of hardness specification.

What will your dealer do?

Your Peterbilt dealer will inspect your truck for suspect components and will replace, as
necessary.

What should you do?

Contact your dealer immediately to schedule an appointment.

Peterbilt has initiated this recall to remedy the issue with no charge to you. Please contact your Peterbilt dealer to schedule an
