WARNING: This page is about a different car, the 2016 Infiniti QX80. However, it is still accessible from the selected car via links, so may be relevant.
  1. Install the differential side shaft. Refer to ASSEMBLY .
  2. Rotate the drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
  3. Rotate the drive pinion at least 20 times to check for smooth operation of the bearings.
  4. Measure total preload torque with the preload gauge [SST: ST3127S000 (J-25765-A)].

    Total preload torque : Refer to PRELOAD TORQUE .
    NOTE:

    Total preload torque = Drive pinion bearing preload torque + Side bearing preload torque 

    • If the measured value is out of the specification, check and adjust each part. Adjust the drive pinion bearing preload torque first, then adjust the side bearing preload torque.
    When the preload torque is large
    On drive pinion bearings: Decrease the drive pinion bearing adjusting washer and drive pinion adjusting washer thickness. For selecting adjusting washer, refer to the latest parts information.
    On side bearings: Increase the side bearing adjusting washer thickness. For selecting adjusting washer, refer to the latest parts information.
    When the preload torque is small
    On drive pinion bearings: Increase the drive pinion bearing adjusting washer and drive pinion adjusting washer thickness. For selecting adjusting washer, refer to the latest parts information.
    On side bearings: Decrease the side bearing adjusting washer thickness. For selecting adjusting washer, refer to the latest parts information.
