Total Preload Torque
WARNING: This page is about a different car, the 2019 Infiniti Q50. However, it is still accessible from the selected car via links, so may be relevant.
- Before inspection and adjustment, drain gear oil.
- Secure final drive assembly onto a suitable attachment.
- Rotate drive pinion back and forth 2 to 3 times to check for unusual noise and rotation malfunction.
- Rotate drive pinion at least 20 times to check for smooth operation of the bearing.
- While rotate drive pinion at 60 RPM, measure total preload with the preload gauge (A) [SST: ST3127S000 (J-25765-A)].
Total preload torque
: Refer to Preload Torque .
NOTE: Total preload torque = Pinion bearing preload torque + Side bearing preload torque- If measured value is out of the specification, disassemble it to check and adjust each part. Adjust the pinion bearing preload and side bearing preload.
Adjust the pinion bearing preload first, then adjust the side bearing preload.
When the preload torque is large
On pinion bearings:
Replace the collapsible spacer.
On side bearings:
Use thinner side bearing adjusting washers by the same amount to each side. For selecting adjusting washer, refer to the latest parts information.
When the preload is small
On pinion bearings:
Tighten the drive pinion lock nut.
On side bearings:
Use thicker side bearing adjusting washers by the same amount to each side. For selecting adjusting washer, refer to the latest parts information.
CAUTION: When replacing side bearing adjusting washer, both right and left side bearing adjusting washers must have the same thickness.
- If measured value is out of the specification, disassemble it to check and adjust each part. Adjust the pinion bearing preload and side bearing preload.
