Front Axle Pinion Gear Inspection
AFFECTED VEHICLES
| Vehicle | Model Year | Assembly Plant | Build Dates |
| F-150 | 2023 | Dearborn | January 17, 2023 through January 24, 2023 |
| Kansas City | January 15, 2023 through January 23, 2023 | ||
| Expedition | Kentucky Truck | January 15, 2023 through January 26, 2023 |
U.S. population of affected vehicles: 239 Affected vehicles are identified in OASIS and FSA VIN Lists.
Note: Some vehicles may be in the process of being repaired at the plant. Monitor OASIS before opening an RO and/or beginning a repair. Parts purchased for an FSA can be returned for credit, if required. See the EXCESS STOCK RETURN details in Attachment II for more information.
NOTE: All originally included Lincoln Navigator vehicles have been confirmed repaired prior to dealership delivery, therefore have been removed from this program and are no longer on demo / delivery hold.
REASON FOR THIS SAFETY RECALL
In some of the affected vehicles, it’s possible the front axle pinion gear was not properly heat treated during the manufacturing process. Pinions that did not receive proper heat treatment may fracture, which may lead to the loss of the 4×4 application with the potential of the front wheels locking up, increasing the risk of a crash.
The failure mode could occur at any time in 4×4 application but is expected to occur primarily while in reverse as the pinion is subject to higher loads.
SERVICE ACTION
Before demonstrating or delivering any new in-stock vehicles involved in this recall, dealers are to inspect the front axle pinion gear for hardness, following the procedure in Attachment III. If a suspect pinion is found, dealers are to replace the front axle assembly. This service must be performed on all affected vehicles at no charge to the vehicle owner.
OWNER NOTIFICATION AND MAILING SCHEDULE
Owner letters are expected to be mailed the week of April 10, 2023. Dealers should repair any affected vehicles that arrive at their dealerships, whether or not the customer has received a letter.
PLEASE NOTE:
Federal law requires dealers to complete this recall service before a new vehicle is delivered to the buyer or lessee. Violation of this requirement by a dealer could result in a civil penalty of up to $26,315 per vehicle. Correct all vehicles in your new vehicle inventory before delivery.
SOLD VEHICLES
- Ford has not issued instructions to stop selling/delivering or driving used vehicles under this safety recall. Owners should contact their dealers for an appointment to have their vehicles remedied as soon as practicable.
- Immediately contact any of your affected customers whose vehicles are not on your VIN list but are identified in OASIS. Give the customer a copy of the Owner Notification Letter (when available) and schedule a service date.
- Correct other affected vehicles identified in OASIS which are brought to your dealership.
- Dealers are to prioritize repairs of customer vehicles over repairs of new and used vehicle inventory.
STOCK VEHICLES
- Correct all affected units in your new vehicle inventory before delivery.
- Use OASIS to identify any affected vehicles in your used vehicle inventory.
DEALER-OPERATED RENTAL VEHICLES

Chronology :
January – February 2023
On January 26, 2023, Ford’s Critical Concern Review Group (CCRG) opened an investigation into reports of front axle pinion fracture on three (3) 2023 model year 4×4 F150 vehicles as they were being backed onto a vehicle transporter. Ford Engineering performed a read-across and determined that, in addition to the F-150 4×4 vehicles, the pinions are also installed on 4×4 Expedition and Lincoln Navigator vehicles.
Initial investigation discovered that the fractured pinions did not go through the required heat treat (annealing) process at Ford’s axle manufacturing plant to reduce hardness and brittleness of the pinion stem threads. A team was immediately dispatched to conduct eddy current hardness checks of all available stock at affected assembly plants. Testing of axle assemblies determined this condition is limited to pinions in 3.73:1 gear ratio axles. The CCRG investigative team reviewed plant process records to determine a build population of suspect dates to derive the population of axles with pinions that may have bypassed the heat treat process.
As of February 13, 2023, Ford is not aware of any warranty, field reports or customer complaints related to this subject.
On February 17, 2023, Ford’s Field Review Committee reviewed the concern and approved a field action.
Ford is not aware of any reports of accident or injury related to this condition.

que el piñón está sujeto a cargas mayores.
¿Qué medidas
adoptarán Ford y su
distribuidor?
Ford Motor Company ha autorizado a su distribuidor a inspeccionar y probar la
rigidez del piñón del eje delantero de su vehículo. Si se determina que
presenta defectos, su distribuidor reemplazará el ensamble del eje delantero,
sin costo alguno (piezas y mano de obra).
¿Cuánto tiempo
tomará?
El tiempo necesario para esta reparación es de menos de un día. Sin
embargo, debido a los requisitos de planificación de servicio, es posible que su
distribuidor tarde un poco más. Además, se realizará una inspección del
vehículo para determinar si se deben solicitar piezas.
¿Qué debe hacer? Llame de inmediato a su distribuidor y solicite una cita de servicio para realizar
la Campaña 23S07. Proporcione el VIN a su distribuidor, el cual está impreso
debajo de sus datos al comienzo de esta carta.
Para esta campaña de seguridad, Ford no ha emitido instrucciones de dejar
manejar el vehículo. Deberá ponerse en contacto con su distribuidor a fin de
programar una cita para solucionar este problema lo más pronto posible.

Affected vehicles are identified in OASIS and FSA VIN Lists.
REASON FOR THIS SAFETY RECALL
In some of the affected vehicles, it’s possible the front axle pinion gear was not properly heat treated
during the manufacturing process. Pinions that did not receive proper heat treatment may fracture,
which may lead to the loss of the 4×4 application with the potential of the front wheels locking up,
increasing the risk of a crash.
The failure mode could occur at any time in 4×4 application but is expected to occur primarily while in
reverse as the pinion is subject to higher loads.
SERVICE ACTION
DO NOT DEMONSTRATE OR DELIVER any new in-stock vehicles involved in this safety recall. A
complete dealer bulletin will be provided to dealers when parts ordering information and repair
instructions are available to support this safety recall.
IMPORTANT: Dealers should open a Repair Order (RO) only when a full dealer bulletin is
published. Opening an RO against an Awareness or Advance Notice will result in warranty
rejections against a recall.
CUSTOMER NOTIFICATION
Owners of record will be notified via first-class mail after repair instructions and parts ordering
information have been provided to dealers.
PLEASE NOTE
Federal law requires dealers to complete this recall service before a new vehicle is delivered to
the buyer or lessee. Violation of this requirement by a dealer could result in a civil penalty of
up to $26,315 per vehicle. Correct all vehicles in your new vehicle inventory prior to delivery.
DEALER-OPERATED RENTAL VEHICLES
The Fixing America’s Surface Transportation (FAST) Act law effective June 2016 prohibits a rental
company from selling, renting, or leasing vehicles subject to a safety or compliance recall. Please
consult your legal counsel for legal advice.
QUESTIONS & ASSISTANCE
For questions and assistance, contact the Special Service Support Center (SSSC) via the SSSC Web
Contact Site. The SSSC Web Contact Site can be accessed through the Professional Technician

U.S. population of affected vehicles: 239 Affected vehicles are identified in OASIS and FSA VIN Lists.
Note: Some vehicles may be in the process of being repaired at the plant. Monitor OASIS before
opening an RO and/or beginning a repair. Parts purchased for an FSA can be returned for credit, if
required. See the EXCESS STOCK RETURN details in Attachment II for more information.
NOTE: All originally included Lincoln Navigator vehicles have been confirmed repaired prior to
dealership delivery, therefore have been removed from this program and are no longer on demo /
delivery hold.
REASON FOR THIS SAFETY RECALL
In some of the affected vehicles, it’s possible the front axle pinion gear was not properly heat treated
during the manufacturing process. Pinions that did not receive proper heat treatment may fracture, which
may lead to the loss of the 4×4 application with the potential of the front wheels locking up, increasing the
risk of a crash.
The failure mode could occur at any time in 4×4 application but is expected to occur primarily while in
reverse as the pinion is subject to higher loads.
SERVICE ACTION
Before demonstrating or delivering any new in-stock vehicles involved in this recall, dealers are to
inspect the front axle pinion gear for hardness, following the procedure in Attachment III. If a suspect
pinion is found, dealers are to replace the front axle assembly. This service must be performed on all
affected vehicles at no charge to the vehicle owner.
OWNER NOTIFICATION MAILING SCHEDULE
Owner letters are expected to be mailed the week of April 10, 2023. Dealers should repair any affected
vehicles that arrive at their dealerships, whether or not the customer has received a letter.
PLEASE NOTE:
Federal law requires dealers to complete this recall service before a new vehicle is delivered to
the buyer or lessee. Violation of this requirement by a dealer could result in a civil penalty of up
to $26,315 per vehicle. Correct all vehicles in your new vehicle inventory before delivery.

Description of the Safety Risk : Pinions that did not receive proper heat treatment may fracture, which may lead to the loss of the 4×4 application with the potential of the front wheels locking up, increasing the risk of a crash.
Description of the Cause : Certain front axle pinions bypassed the heat treat process at the axle manufacturing plant. The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-128 Page 3 Identification of Any Warning
that can Occur : The driver may hear a loud noise when the pinion breaks or as the drive shaft and flange hit the frame cross member and stability bar after pinion fracture. The failure mode could occur at any time in 4×4 application but is expected to occur primarily while in reverse as the pinion is subject to higher loads.

Name : Ford Motor Company Address : 1 American Road
Dearborn Michigan 48126
Country : United States Chronology :
January – February 2023
On January 26, 2023, Ford’s Critical Concern Review Group (CCRG) opened an investigation into reports of front axle pinion fracture on three (3) 2023 model year 4×4 F150 vehicles as they were being backed onto a vehicle transporter. Ford Engineering performed a read-across and determined that, in addition to the F-150 4×4 vehicles, the pinions are also installed on 4×4 Expedition and Lincoln Navigator vehicles. Initial investigation discovered that the fractured pinions did not go through the required heat treat (annealing) process at Ford’s axle manufacturing plant to reduce hardness and brittleness of the pinion stem threads. A team was immediately dispatched to conduct eddy current hardness checks of all available stock at affected assembly plants. Testing of axle assemblies determined this condition is limited to pinions in 3.73:1 gear ratio axles. The CCRG investigative team reviewed plant process records to determine a build population of suspect dates to derive the population of axles with pinions that may have bypassed the heat treat process. As of February 13, 2023, Ford is not aware of any warranty, field reports or customer complaints related to this subject. On February 17, 2023, Ford’s Field Review Committee reviewed the concern and approved a field action. The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-128
Page 4
The information contained in this report was submitted pursuant to 49 CFR §573
Ford is not aware of any reports of accident or injury related to this condition.
Description of Remedy :
Description of Remedy Program : Owners will be notified by mail and instructed to take their vehicle to a
Ford or Lincoln dealer to have the front axle pinion gear set replaced. Vehicles with a broken front axle pinion will have the entire axle assembly replaced. There will be no charge for this service.
Ford provided the general reimbursement plan for the cost of remedies paid for by vehicle owners prior to notification of a safety recall in May 2021. The ending date for reimbursement eligibility is estimated to be December 31, 2023. Ford will forward a copy of the notification letters to dealers to the agency when available.
How Remedy Component Differs from Recalled Component :
Identify How/When Recall Condition was Corrected in Production :
The replacement front axle pinion gear set (CL3Z-3222-D) has the required heat treatment process (annealing).

Description of the Defect : The front axle pinion may not have been heat-treated, which can cause it to fracture.
FMVSS 1 : NR FMVSS 2 : NR
Description of the Safety Risk : Pinions that did not receive proper heat treatment may fracture, which may lead to the loss of the 4×4 application with the potential of the front wheels locking up, increasing the risk of a crash.
Description of the Cause : Certain front axle pinions bypassed the heat treat process at the axle manufacturing plant. The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-128 Page 3 Identification of Any Warning
that can Occur : The driver may hear a loud noise when the pinion breaks or as the drive shaft and flange hit the frame cross member and stability bar after pinion fracture. The failure mode could occur at any time in 4×4 application but is expected to occur primarily while in reverse as the pinion is subject to higher loads.

Country : United States Chronology :
January – February 2023
On January 26, 2023, Ford’s Critical Concern Review Group (CCRG) opened an investigation into reports of front axle pinion fracture on three (3) 2023 model year 4×4 F150 vehicles as they were being backed onto a vehicle transporter. Ford Engineering performed a read-across and determined that, in addition to the F-150 4×4 vehicles, the pinions are also installed on 4×4 Expedition and Lincoln Navigator vehicles. Initial investigation discovered that the fractured pinions did not go through the required heat treat (annealing) process at Ford’s axle manufacturing plant to reduce hardness and brittleness of the pinion stem threads. A team was immediately dispatched to conduct eddy current hardness checks of all available stock at affected assembly plants. Testing of axle assemblies determined this condition is limited to pinions in 3.73:1 gear ratio axles. The CCRG investigative team reviewed plant process records to determine a build population of suspect dates to derive the population of axles with pinions that may have bypassed the heat treat process. As of February 13, 2023, Ford is not aware of any warranty, field reports or customer complaints related to this subject. On February 17, 2023, Ford’s Field Review Committee reviewed the concern and approved a field action. The information contained in this report was submitted pursuant to 49 CFR §573 Part 573 Safety Recall Report 23V-128

Description of Remedy :
Description of Remedy Program : Owners will be notified by mail and instructed to take their vehicle to a
Ford or Lincoln dealer to have the front axle pinion gear set replaced. Vehicles with a broken front axle pinion will have the entire axle assembly replaced. There will be no charge for this service.
Ford provided the general reimbursement plan for the cost of remedies paid for by vehicle owners prior to notification of a safety recall in May 2021. The ending date for reimbursement eligibility is estimated to be December 31, 2023. Ford will forward a copy of the notification letters to dealers to the agency when available.
How Remedy Component Differs from Recalled Component :
Identify How/When Recall Condition was Corrected in Production :
The replacement front axle pinion gear set (CL3Z-3222-D) has the required heat treatment process (annealing).
