Symptoms
Owners of affected Nissan AWD models may experience an "abnormal noise, vibration and/or judder from the rear differential area of the vehicle." This issue specifically affects the all-wheel-drive or four-wheel-drive systems.
Diagnosis and Trigger Conditions
Diagnosing the source of the "Nissan AWD rear differential noise" involves a systematic approach outlined in a flow chart. Technicians first confirm if the abnormal noise, vibration, or judder is present from the rear final drive assembly. If confirmed, the Electric Controlled Coupling is disconnected and the vehicle is retested to determine if the noise persists.
A stethoscope is used to test for noise at both the Electric Controlled Coupling and the center rear of the Final Drive Assembly. The technician compares the loudness to a Known Good Vehicle (KGV) to determine if the noise is excessive and where it is loudest. If the noise is louder at the Coupler Clutch area, it points to the Electric Controlled Coupling. If louder at the center rear of the Final Drive Assembly, it indicates an issue with the Final Drive Assembly.
For 2021-2022 Rogue and 2022 Pathfinder models, a new AWD coupler system with a hydraulic clutch pressure and oil pump is used. It is considered normal operation to hear the pump prime when the ignition is turned on. If the abnormal noise is only heard at startup with the vehicle not moving, a priming operation on the Coupler Actuator should be performed. If the noise is still louder than a KGV after this, it indicates a potential issue with the Electric Controlled Coupling.
Repair Procedure Summary
Once the source of the "Nissan AWD rear differential noise" is identified, the repair procedure focuses on replacing the specific faulty component. If the noise is determined to be louder from the Final Drive Assembly, the entire Rear Final Drive Assembly is replaced. Conversely, if the noise is louder from the Electric Controlled Coupling, only the Electric Controlled Coupling is replaced.
Detailed removal and installation instructions are found in the Electronic Service Manual (ESM) for each specific vehicle model and year. Examples of ESM sections include:
For Electric Controlled Coupling replacement:
- 2019-2022 Altima, 2009-2022 Murano and Murano Hybrid, 2008-2020 Rogue, Rogue Select, and Rogue Hybrid: TRANSMISSION & DRIVELINE > DRIVELINE > REAR FINAL DRIVE: R145 > REMOVAL AND INSTALLATION > ELECTRIC CONTROLLED COUPLING
- 2003-2007 Murano: Section RFD – Rear Final Drive
- 2013-2020 Pathfinder and Pathfinder Hybrid: TRANSMISSION & DRIVELINE > DRIVELINE > REAR FINAL DRIVE: R145K1 > REMOVAL AND INSTALLATION > ELECTRIC CONTROLLED COUPLING
- 2022 Pathfinder and 2021-2022 Rogue: TRANSMISSION & DRIVELINE > DRIVELINE > REAR FINAL DRIVE: R145 > REMOVAL AND INSTALLATION > ELECTRO-HYDRAULIC COUPLING
- 2017-2022 Rogue Sport: REPAIR > TRANSMISSION & DRIVELINE > DRIVELINE > REMOVAL AND INSTALLATION > ELECTRIC CONTROLLED COUPLING
For Rear Final Drive Assembly replacement:
- 2019-2022 Altima: TRANSMISSION & DRIVELINE > DRIVELINE > REAR FINAL DRIVE: R145 > REMOVAL AND INSTALLATION > REAR FINAL DRIVE ASSEMBLY
- 2003-2007 Murano: Section RFD – Rear Final Drive
- 2009-2022 Murano and Murano Hybrid, 2008-2020 Rogue, Rogue Select, and Rogue Hybrid: TRANSMISSION & DRIVELINE > DRIVELINE > REAR FINAL DRIVE: R145 > UNIT REMOVAL AND INSTALLATION > REAR FINAL DRIVE ASSEMBLY
- 2013-2020 Pathfinder: TRANSMISSION & DRIVELINE > DRIVELINE > REAR FINAL DRIVE: R145K1 > UNIT REMOVAL AND INSTALLATION > REAR FINAL DRIVE ASSEMBLY
- 2022 Pathfinder and 2021-2022 Rogue: TRANSMISSION & DRIVELINE > DRIVELINE > REAR FINAL DRIVE: R145 > UNIT REMOVAL AND INSTALLATION > REAR FINAL DRIVE ASSEMBLY
- 2017-2022 Rogue Sport: REPAIR > TRANSMISSION & DRIVELINE > DRIVELINE > REMOVAL AND INSTALLATION > REAR FINAL DRIVE ASSEMBLY
After replacing either the Electric Controlled Coupling or the Final Drive Assembly, a critical step called "Unit Characteristics Writing" must be performed on some models using the CONSULT-III plus diagnostic tool. This ensures proper calibration and function of the new component within the AWD system. Specific ESM sections for this procedure include:
- 2019-2022 Altima: TRANSMISSION & DRIVELINE > DRIVELINE > TRANSFER: TY21D > BASIC INSPECTION > AWD SYSTEM > UNIT CHARACTERISTICS WRITING
- 2015-2022 Murano and Murano Hybrid, 2015-2020 Pathfinder and Pathfinder Hybrid, and 2014-2020 Rogue and Rogue Hybrid: TRANSMISSION & DRIVELINE > DRIVELINE > TRANSFER: TY21C > BASIC INSPECTION > UNIT CHARACTERISTICS WRITING
- 2022 Pathfinder: TRANSMISSION & DRIVELINE > DRIVELINE > TRANSFER: TY92B > BASIC INSPECTION > ADDITIONAL SERVICE WHEN REPLACING AWD CONTROL UNIT (IN ELECTRO-HYDRAULIC COUPLING)
- 2021-2022 Rogue: TRANSMISSION & DRIVELINE > DRIVELINE > TRANSFER: TY92A > BASIC INSPECTION > ADDITIONAL SERVICE WHEN REPLACING AWD CONTROL UNIT (IN ELECTRO-HYDRAULIC COUPLING)
- 2017-2022 Rogue Sport: TRANSMISSION & DRIVELINE > DRIVELINE > BASIC INSPECTION > AWD SYSTEM > UNIT CHARACTERISTICS WRITING

Important Warnings
Owners and technicians should be aware of several important considerations related to this issue:
- Tire Mismatch: "Tire size, brand or tread pattern mismatches can cause similar symptoms. To avoid tire related mismatch vibration, it is recommended that when tires need to be replaced, all tires are replaced at the same time with tires of the proper size, same brand and pattern."
- Component Replacement: If diagnosis leads to replacement of the Electric Controlled Coupling, technicians are advised: "DO NOT replace the entire Rear Final Drive Assembly." Similarly, "DO NOT remove the Rear Final Drive Assembly for this procedure" when only replacing the Electric Controlled Coupling. This prevents unnecessary and costly repairs.
- Professional Service: Nissan emphasizes that these bulletins are "intended for use by qualified technicians, not 'do-it-yourselfers'." Proper training, equipment, and safety instructions are essential for successful and safe repairs. Owners should not assume a described condition applies to their vehicle without dealer confirmation.
