2013-2016 CX-5 AWD – RATTLE / CHATTER NOISE FROM REAR DIFFERENTIAL
APPLICABLE MODEL(S)/VINS
2013-2016 CX-5 AWD vehicles with VINs lower than JM3KE******725078 (produced before October 1, 2015)
While driving at low speeds, some vehicles may exhibit a chattering / rattling type noise from the rear of the vehicle.
The noise may be caused by a rear differential bearing failure.
The following mass-production changes have been implemented to eliminate the noise.
| Description | Starting VIN and Production Date |
| 1. The assembly process was improved. | JM3KE******391989 (September 16, 2013) |
| 2. The shape of the coupling unit housing was changed. | JM3KE******725078 (October 1, 2015) |
REPAIR PROCEDURE
- Lift the vehicle according to the instructions on MS3 online or the Workshop Manual (section 00-00).
- Verify the noise is heard from the rear differential component (A) when the wheel speed is approximately 3 to 6 mph (5 to 10 km/h).

- Has the noise been verified?
- Yes – Proceed to step 4.
- No – This does not apply. Refer to MS3 online or Workshop Manual (section 03-03).
- Replace the rear differential component (including the coupling unit). Refer to MS3 online or Workshop Manual (section 03-14).
CAUTION: If the constant velocity joint angle is excessive during propeller shaft removal/installation, the constant velocity joint boot may be damaged when contacting the metallic cover. Protect the constant velocity joint boot by inserting a shop rag (A) between the boot and the metallic cover.
COUPLING COMPONENT CALIBRATION DATA WRITING:
CAUTION: After part replacement, write characteristic value of new coupling component to 4WD control module (from M-MDS toolbox, “Chassis”, “4WD/AWD”, “Coupling Calibration Data Writing”). If this is not completed, it may result in the following conditions: – The system will not operate normally. – Coupling component durability problems may occur. Obtain characteristic value from label (A) or mark (B) locations shown below.
PART(S) INFORMATION
| Part Number | Description | Qty. | Notes |
| KAT1-27-020A | Rear Differential Component | 1 | — |
PE23-40-305  | Gasket | 2 | Part not reusable |
| 9994-61-000 | Nut | 4 | Part not reusable |

PARTS INTERCHANGEABILITY:
NOTE:
- New coupling unit (A) (KE01-27-97XA) and differential housing (B) are used during mass-production.
- New coupling unit IS NOT INTERCHANGEABLE WITH THE OLD DIFFERENTIAL HOUSING due to an increase in guide (C) length.
IDENTIFY DIFFERENTIAL HOUSING:
- The OLD differential housing has no suffix (KA01-27-151) in the molded part number (as shown below).
- The NEW differential housing has an “A” suffix (KA01-27-151A) in the molded part number.
