Owners of 2019-2022 Nissan AWD models, including the Altima, Murano, Pathfinder, Rogue, and Rogue Sport, may experience an "abnormal noise, vibration and/or judder from the rear differential area." Nissan Technical Service Bulletin (TSB) NTB10-029G provides a comprehensive guide for technicians to diagnose and repair this condition.
This bulletin, last amended on March 15, 2022, supersedes previous versions and offers detailed steps to identify whether the Electric Controlled Coupling (ECC) or the entire Rear Final Drive Assembly is the source of the Nissan Rogue rear differential noise or other symptoms.
Symptoms
If you own a 2019-2022 Nissan AWD vehicle and notice any of the following, your vehicle may be affected by the condition described in TSB NTB10-029G:
- Abnormal noise from the rear differential area.
- Vibration originating from the rear differential area.
- Judder (a shuddering or shaking sensation) from the rear differential area.
Important Warnings
Nissan has provided several critical warnings within TSB NTB10-029G that owners and technicians should be aware of:
- "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."
- If diagnosis leads to replacement of the Electric Controlled Coupling, technicians are advised: "DO NOT replace the entire Rear Final Drive Assembly." and "DO NOT remove the Rear Final Drive Assembly for this procedure. The Electric Controlled Coupling can be replaced with the Rear Final Drive Assembly in the vehicle."
- "Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'."
Diagnosis Procedure
The diagnostic process outlined in TSB NTB10-029G involves a detailed flow chart to pinpoint the exact cause of the abnormal noise, vibration, or judder from the rear differential area. Here's a summary of the steps:
- Initial Confirmation: Verify the presence of an "abnormal noise, vibration and/or judder from the rear Final Drive Assembly."
- Electric Controlled Coupling Disconnect Test: Disconnect the Electric Controlled Coupling and retest the vehicle. If the noise, vibration, and/or judder are no longer present, the issue lies with the Electric Controlled Coupling.
- Model-Specific Check (2021-2022 Rogue / 2022 Pathfinder): If the symptoms persist after disconnecting the ECC, check if the vehicle is a 2021-2022 Rogue or 2022 Pathfinder. These models feature a new AWD coupler system with hydraulic clutch pressure and an oil pump. 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, technicians should run the priming operation on the Coupler Actuator. If the noise is still louder than a KGV (a specific noise level reference), the Electric Controlled Coupling should be replaced. Otherwise, this bulletin does not apply.
- Stethoscope Test: If the vehicle is not a 2021-2022 Rogue or 2022 Pathfinder, or if the noise is not limited to startup, use a stethoscope to test for noise at both the Coupler Clutch area of the Electric Controlled Coupling and the center rear of the Final Drive Assembly.
- Noise Localization and Repair:
- If the noise is louder than a KGV only at the center rear of the Final Drive Assembly, replace the Final Drive Assembly.
- If the noise is louder than a KGV only at the Electric Controlled Coupling, replace the Electric Controlled Coupling.
Repair Procedure Summary
Depending on the diagnosis, the repair will involve either replacing the Electric Controlled Coupling or the entire Rear Final Drive Assembly. Technicians must refer to the Electronic Service Manual (ESM) for detailed removal and installation procedures.
Electric Controlled Coupling Replacement
If diagnosis indicates the Electric Controlled Coupling needs replacement, Nissan explicitly states: "DO NOT replace the entire Rear Final Drive Assembly." and "DO NOT remove the Rear Final Drive Assembly for this procedure. The Electric Controlled Coupling can be replaced with the Rear Final Drive Assembly in the vehicle." Technicians should consult the ESM sections relevant to the specific model and year:
- 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:
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
Rear Final Drive Assembly Replacement
If the diagnosis points to the entire Rear Final Drive Assembly, technicians should refer to the following ESM sections:
- 2019-2022 Altima:
TRANSMISSION & DRIVELINE > DRIVELINE > REAR FINAL DRIVE: R145 > REMOVAL AND INSTALLATION > REAR FINAL DRIVE ASSEMBLY - 2003-2007 Murano:
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 - 2017-2021 Rogue Sport:
REPAIR > TRANSMISSION & DRIVELINE > DRIVELINE > REMOVAL AND INSTALLATION > REAR FINAL DRIVE ASSEMBLY
Unit Characteristics Writing
After replacing either the Electric Controlled Coupling or the Final Drive Assembly, performing "Unit Characteristics Writing" using the CONSULT-III plus diagnostic tool is a required step for some models. This ensures proper calibration and integration of the new component with the vehicle's AWD system. Refer to the ESM for specific instructions:
- 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:
