This bulletin will be updated when parts and repair procedures are available.
Introduction
Peterbilt
Motors has determined that a defect, which relates to motor vehicle safety, exists in certain Model Year 2022-2023 325, 330, 337, 348, 365, 367, 389, 520, 536, 537, 548, 567, 579, and New Model 579 chassis built from 06/01/2021 through 06/16/2022. The steering gear may have been incorrectly assembled, which could cause the steering gear to fracture, resulting in loss of steering control and increased risk of a crash.
Some steering gears were assembled with fewer than the required number of recirculating balls which can lead to a fracture in the steering gear worm shaft and loss of vehicle steering.
Steering gears with fewer than the required number of recirculating balls may bind when loads are applied. In some cases, the balls may align on the same side of the gear’s worm shaft and concentrated loads may cause the gear’s internal parts to fracture resulting in loss of vehicle steering. Loss of steering increases the likelihood of a crash.
Preceding the intern l fracture, the steering may be perceived as strained by the driver. No audible or visual warning is available.
Situation
22,538 (21.189 US and 1,349 CAN) Model Year 2022-2023 325, 330, 337, 348, 365, 367, 389, 520, 536, 537, 548,567, 579, and New Model 579 chassis built from 06/16/2021 through 06/02/2022 with suspect steering gears.

5-20 RH Sheppard communicated they were filing equipment recall due to steering gear shaft failures on two warranty returns. No root cause or remedy.
5-24 RHS sent list of suspect steering gear orders.
5-26 RHS provided instructions for reading serial numbers and range for suspect parts. Plants began inspecting and quarantining material. RHS testing if gears can be tested on trucks to determine good gears. RHS doing infant failure analysis.
5-27 RHS provided some suspect part numbers.
6-01 RHS sent list of serial numbers checked so far as being cleared. Plants re-sort and release parts. Plants had quarantined by the suspect year/month and could now release specific steering gear serial numbers.
6-03 Warranty search found 2 claims match known failures.
6-07 RHS sent larger list of serial numbers that currently makes up the suspect gear serial number population. Plants re-sort and release parts.
6-08 RHS identified root cause to be recirculating balls removed during re-work and new ball insertion process not completed.
6-09 RHS reduced the suspect population to 2,816 serial numbers. Plants re-sort and release parts.
6-16 RHS sent new suspect population with 2,877 serial numbers. Plants re-sort and release parts. Safety and Compliance asked for PACCAR
part number, plant location and invoice date to be added to suspect population list.

Description of Remedy : Description of Remedy Program : Dealers will inspect vehicles to determine whether the steering gear serial number is on Sheppard’s list of suspect serial numbers. Any steering gear on the suspect list will be replaced. Owners who incurred costs to obtain a remedy for the problem addressed by the recall in advance of receiving notification may seek reimbursement through the process outlined in the general reimbursement plan on file. How Remedy Component Differs from Recalled Component : Identify How/When Recall Condition was Corrected in Production : The only way to distinguish a recalled gear and a remedy component is by checking the steering gear serial number. A lockout timer was added that requires any steering gear that is in the ball drop station too long has to remove all recirculating balls and do a new ball drop. Recall Schedule : Description of Recall Schedule : Notifications will be sent within 60 days. Planned Dealer Notification Date : SEP 26, 2022 – SEP 26, 2022 Planned Owner Notification Date : SEP 26, 2022 – SEP 26, 2022 * NR – Not Reported

Production Dates : JUN 02, 2021 – JUN 02, 2022 VIN Range 1 : Begin : NR End : NR Not sequential Description of Defect : Description of the Defect : Steering gear was assembled with fewer than the required number of recirculating balls which can lead to a fracture in the steering gear worm-shaft and loss of vehicle steering. FMVSS 1 : NR FMVSS 2 : NR Part 573 Safety Recall Report 22V-547 Page 2 The information contained in this report was submitted pursuant to 49 CFR §573 Description of the Safety Risk : A steering gear with fewer than the required number of recirculating balls may bind when loads are applied. In some cases the balls may align on the same side of the gear’s worm-shaft and concentrated loads may cause the gear’s internal parts to fracture resulting in loss of vehicle steering. Loss of steering increases the likelihood of a crash. Description of the Cause : Incorrect re-work allowed steering gear to be assembled with fewer than the required number of recirculating balls. Identification of Any Warning that can Occur : Preceding the internal fracture, the steering may be perceived as strained by the driver. No audible or visual warning is associated with this defect.
